+Pico Changelog
+==============
+
+**Note:** This changelog only provides technical information about the changes
+          introduced with a particular Pico version, and is meant to supplement
+          the actual code changes. The information in this changelog are often
+          insufficient to understand the implications of larger changes. Please
+          refer to both the UPGRADE and NEWS sections of the docs for more
+          details.
+
+**Note:** Changes breaking backwards compatibility (BC) are marked with an `!`
+          (exclamation mark). This doesn't include changes for which BC is
+          preserved by Pico's official `PicoDeprecated` plugin. If a previously
+          deprecated feature is later removed in `PicoDeprecated`, this change
+          is going to be marked as BC-breaking change in both Pico's and
+          `PicoDeprecated`'s changelog. Please note that BC-breaking changes
+          are only possible with a new major version.
+
+### Version 2.1.4
+Released: 2020-08-29
+
+```
+* [Changed] Silence PHP errors in Parsedown
+* [Fixed] #560: Improve charset guessing for formatted date strings using
+          `strftime()` (Pico always uses UTF-8, but `strftime()` might not)
+```
+
+### Version 2.1.3
+Released: 2020-07-10
+
+```
+* [New] Add `locale` option to `config/config.yml`

+```
+
+### Version 2.1.2
+Released: 2020-04-10
+
+```
+* [Fixed] Fix DummyPlugin declaring API version 3
+```
+
+### Version 2.1.1
+Released: 2019-12-31
+
+```
+* [Fixed] Require Parsedown 1.8.0-beta-7 and Parsedown Extra 0.8.0-beta-1 due
+          to changes in Parsedown and Parsedown Extra breaking BC beyond repair
+* [Changed] #523: Check for hidden pages based on page ID instead of full paths
+* [Changed] Improve Pico docs
+```
+
+### Version 2.1.0

+            the usage of the new image utility classes of Pico's default theme
+* [Changed] Improve Pico docs and PHPDoc class docs
+```
+
+### Version 2.1.0-beta.1
+Released: 2019-11-03
+
+```
+* [New] Introduce API version 3
+* [New] Add `assets_dir`, `assets_url` and `plugins_url` config params
+* [New] Add `%config.*%` Markdown placeholders for scalar config params and the
+        `%assets_url%`, `%themes_url%` and `%plugins_url%` placeholders
+* [New] Add `content-sample/theme.md` for theme testing purposes
+* [New] Introduce API versioning for themes and support theme-specific configs
+        using the new `pico-theme.yml` in a theme's directory; `pico-theme.yml`
+        allows a theme to influence Pico's Twig config, to register known meta
+        headers and to provide defaults for theme config params
+* [New] Add `assets_url`, `themes_url` and `plugins_url` Twig variables
+* [New] Add `pages` Twig function to deal with Pico's page tree; this function
+        replaces the raw usage of Pico's `pages` array in themes
+* [New] Add `url` Twig filter to replace URL placeholders (e.g. `%base_url%`)
+        in strings using the new `Pico::substituteUrl()` method
+* [New] Add `onThemeLoading` and `onThemeLoaded` events
+* [New] Add `debug` config param and the `Pico::isDebugModeEnabled()` method,
+        checking the `PICO_DEBUG` environment variable, to enable debugging
+* [New] Add new `Pico::getNormalizedPath()` method to normalize a path; this
+        method should be used to prevent content dir breakouts when dealing
+        with paths provided by user input
+* [New] Add new `Pico::getUrlFromPath()` method to guess a URL from a file path
+* [New] Add new `Pico::getAbsoluteUrl()` method to make a relative URL absolute
+* [New] #505: Create pre-built `.zip` release archives
+* [Fixed] #461: Proberly handle content files with a UTF-8 BOM
+* [Changed] Rename `theme_url` config param to `themes_url`; the `theme_url`
+            Twig variable and Markdown placeholder are kept unchanged
+* [Changed] Update to Parsedown Extra 0.8 and Parsedown 1.8 (both still beta)
+* [Changed] Enable Twig's `autoescape` feature by default; outputting a
+            variable now causes Twig to escape HTML markup; Pico's `content`
+            variable is a notable exception, as it is marked as being HTML safe
+* [Changed] Rename `prev_page` Twig variable to `previous_page`
+* [Changed] Mark `markdown` and `content` Twig filters as well as the `content`
+            variable as being HTML safe
+* [Changed] Add `$singleLine` param to `markdown` Twig filter as well as the
+            `Pico::parseFileContent()` method to parse just a single line of
+            Markdown input
+* [Changed] Add `AbstractPicoPlugin::configEnabled()` method to check whether
+            a plugin should be enabled or disabled based on Pico's config
+* [Changed] Deprecate the use of `AbstractPicoPlugin::__call()`, use
+            `PicoPluginInterface::getPico()` instead
+* [Changed] Update to Twig 1.36 as last version supporting PHP 5.3, use a
+            Composer-based installation to use a newer Twig version
+* [Changed] Add `$basePath` and `$endSlash` params to `Pico::getAbsolutePath()`
+* [Changed] Deprecate `Pico::getBaseThemeUrl()`
+* [Changed] Replace various `file_exists` calls with proper `is_file` calls
+* [Changed] Refactor release & build system
+* [Changed] Improve Pico docs and PHPDoc class docs
+* [Changed] Various small improvements
+* [Removed] Remove superfluous `base_dir` and `theme_dir` Twig variables
+* [Removed] Remove `PicoPluginInterface::__construct()`
+```
+
+### Version 2.0.5-beta.1

+
+```
+* [New] Add PHP 7.3 tests
+* [New] Add `2.0.x-dev` alias for master branch to `composer.json`

+```
+
+### Version 2.0.1
+Released: 2018-07-29
+
+```
+* [Changed] Improve documentation
+* [Changed] Add missing "Formatted Date", "Time" and "Hidden" meta headers; use
+            the "Hidden" meta header to manually hide a page in the pages list
+```
+
+### Version 2.0.0
+Released: 2018-07-01

+Released: 2018-01-21
+
+```
+* [New] Improve release & build process and move most build tools to the new
+        `picocms/ci-tools` repo, allowing them to be used by other projects
+* [New] Add page tree; refer to the `Pico::buildPageTree()` method for more
+        details; also see the `onPageTreeBuilt` event
+* [Changed] Update dependencies: Twig 1.35
+* [Changed] ! Improve `.htaccess` and deny access to all dot files by default
+* [Changed] ! Throw a `RuntimeException` when non-native plugins are loaded,
+            but Pico's `PicoDeprecated` plugin is not loaded
+* [Changed] ! Change `AbstractPicoPlugin::$enabled`'s behavior: setting it to
+            TRUE now leads to throwing a `RuntimeException` when the plugin's
+            dependencies aren't fulfilled; use NULL to maintain old behavior
+* [Changed] ! Force themes to use `.twig` as file extension for Twig templates
+* [Changed] Improve PHP class docs
+* [Changed] Various small improvements
+```
+
+### Version 2.0.0-beta.1
+Released: 2017-11-05
+
+```
+* [New] Pico is on its way to its second major release!
+* [New] Improve Pico's release & build process
+* [New] Add "Developer Certificate of Origin" to `CONTRIBUTING.md`
+* [New] Add license & copyright header to all relevant files
+* [New] Add Pico version constants (`Pico::VERSION` and `Pico::VERSION_ID`),
+        and add a `version` Twig variable and `%version%` Markdown placeholder
+* [New] Add Pico API versioning for plugins (see `Pico::API_VERSION` constant);
+        Pico now triggers events on plugins using the latest API version only
+        ("native" plugins), `PicoDeprecated` takes care of all other plugins;
+        as a result, old plugin's always depend on `PicoDeprecated` now
+* [New] Add a theme and plugin installer for composer; Pico now additionally
+        uses the new `vendor/pico-plugin.php` file to discover plugins
+        installed by composer and loads them using composer's autoloader;
+        see the `picocms/composer-installer` repo for more details; Pico
+        loads plugins installed by composer first and ignores conflicting
+        plugins in Pico's `plugins/` dir
+* [New] Add `$enableLocalPlugins` parameter to `Pico::__construct()` to allow
+        website developers to disable local plugin discovery by scanning the
+        `plugins/` dir (i.e. load plugins from `vendor/pico-plugin.php` only)
+* [New] Add public `AbstractPicoPlugin::getPluginConfig()` method
+* [New] Add public `Pico::loadPlugin()` method and the corresponding
+        `onPluginManuallyLoaded` event
+* [New] Add public `Pico::resolveFilePath()` method (replaces the protected
+        `Pico::discoverRequestFile()` method)
+* [New] Add public `Pico::is404Content()` method
+* [New] Add public `Pico::getYamlParser()` method and the corresponding
+        `onYamlParserRegistered` event
+* [New] Add public `Pico::substituteFileContent()` method
+* [New] Add public `Pico::getPageId()` method
+* [New] Add public `Pico::getFilesGlob()` method
+* [New] Add public `Pico::getVendorDir()` method, returning Pico's installation
+        directory (i.e. `/var/www/pico/vendor/picocms/pico`); don't confuse
+        this with composer's `vendor/` dir!
+* [New] Add `$default` parameter to `Pico::getConfig()` method
+* [New] Add empty `assets/` and `content/` dirs
+* [New] #305: Add `url_param` and `form_param` Twig functions, and the public
+        `Pico::getUrlParameter()` and `Pico::getFormParameter()` methods,
+        allowing theme developers to access URL GET and HTTP POST parameters
+* [New] Add `$meta` parameter to `markdown` Twig filter
+* [New] Add `remove` fallback to `sort_by` Twig filter
+* [New] Add `theme_url` config parameter
+* [New] Add public `Pico::getBaseThemeUrl()` method
+* [New] Add `REQUEST_URI` routing method, allowing one to simply rewrite all
+        requests to `index.php` (e.g. use `FallbackResource` or `mod_rewrite`
+        in your `.htaccess` for Apache, or use `try_files` for nginx)
+* [New] #299: Add built-in 404 page as fallback when no `404.md` is found
+* [New] Allow sorting pages by arbitrary meta values
+* [New] Add `onSinglePageLoading` event, allowing one to skip a page
+* [New] Add `onSinglePageContent` event
+* [New] Add some config parameters to change Parsedown's behavior
+* [Changed] ! Disallow running the same Pico instance multiple times by
+            throwing a `RuntimeException` when calling `Pico::run()`
+* [Changed] ! #203: Load plugins from `plugins/<plugin name>/<plugin name>.php`
+            and `plugins/<plugin name>.php` only (directory and file name must
+            match case-sensitive), and throw a `RuntimeException` when Pico is
+            unable to load a plugin; also throw a `RuntimeException` when
+            superfluous files or directories in `plugins/` are found; use a
+            scope-isolated `require()` to include plugin files
+* [Changed] ! Use a plugin dependency topology to sort `Pico::$plugins`,
+            changing the execution order of plugins so that plugins, on which
+            other plugins depend, are always executed before their dependants
+* [Changed] ! Don't pass `$plugins` parameter to `onPluginsLoaded` event by
+            reference anymore; use `Pico::loadPlugin()` instead
+* [Changed] ! Leave `Pico::$pages` unsorted when a unknown sort method was
+            configured; this usually means that a plugin wants to sort it
+* [Changed] Overhaul page discovery events: add `onPagesDiscovered` event which
+            is triggered right before `Pico::$pages` is sorted and move the
+            `$currentPage`, `$previousPage` and `$nextPage` parameters of the
+            `onPagesLoaded` event to the new `onCurrentPageDiscovered` event
+* [Changed] Move the `$twig` parameter of the `onPageRendering` event to the
+            `onTwigRegistered` event, replacing the `onTwigRegistration` event
+* [Changed] Unify the `onParsedownRegistration` event by renaming it to
+            `onParsedownRegistered` and add the `$parsedown` parameter
+* [Changed] #330: Replace `config/config.php` by a modular YAML-based approach;
+            you can now use a arbitrary number of `config/*.yml` files to
+            configure Pico
+* [Changed] ! When trying to auto-detect Pico's `content` dir, Pico no longer
+            searches just for a (possibly empty) directory, but rather checks
+            whether a `index.md` exists in this directory
+* [Changed] ! Use the relative path between `index.php` and `Pico::$themesDir`
+            for Pico's theme URL (also refer to the new `theme_url` config and
+            the public `Pico::getBaseThemeUrl()` method for more details)
+* [Changed] #347: Drop the superfluous trailing "/index" from Pico's URLs
+* [Changed] Flip registered meta headers array, so that the array key is used
+            to search for a meta value and the array value is used to store the
+            found meta value (previously it was the other way round)
+* [Changed] ! Add lazy loading for `Pico::$yamlParser`, `Pico::$parsedown` and
+            `Pico::$twig`; the corresponding events are no longer part of
+            Pico's event flow and are triggered on demand
+* [Changed] ! Trigger the `onMetaHeaders` event just once; the event is no
+            longer part of Pico's event flow and is triggered on demand
+* [Changed] Don't lower meta headers on the first level of a page's meta data
+            (i.e. `SomeKey: value` is accessible using `$meta['SomeKey']`)
+* [Changed] Don't compare registered meta headers case-insensitive, require
+            matching case
+* [Changed] Allow users to explicitly set values for the `date_formatted` and
+            `time` meta headers in a page's YAML front matter
+* [Changed] Add page siblings for all pages
+* [Changed] ! Treat pages or directories that are prefixed by `_` as hidden;
+            when requesting a hidden page, Pico responds with a 404 page;
+            hidden pages are still in `Pico::$pages`, but are moved to the end
+            of the pages array when sorted alphabetically or by date
+* [Changed] ! Don't treat explicit requests to a 404 page as successful request
+* [Changed] Change method visibility of `Pico::getFiles()` to public
+* [Changed] Change method visibility of `Pico::triggerEvent()` to public;
+            at first glance this method triggers events on native plugins only,
+            however, `PicoDeprecated` takes care of triggering events for other
+            plugins, thus you can use this method to trigger (custom) events on
+            all plugins; never use it to trigger Pico core events!
+* [Changed] Move Pico's default theme to the new `picocms/pico-theme` repo; the
+            theme was completely rewritten from scratch and is a much better
+            starting point for creating your own theme; refer to the theme's
+            `CHANGELOG.md` for more details
+* [Changed] Move `PicoDeprecated` plugin to the new `picocms/pico-deprecated`
+            repo; refer to the plugin's `CHANGELOG.md` for more details
+* [Changed] Update dependencies: Twig 1.34, Symfony YAML 2.8, Parsedown 1.6
+* [Changed] Improve Pico docs and PHP class docs
+* [Changed] A vast number of small improvements and changes...
+* [Removed] ! Remove `PicoParsePagesContent` plugin
+* [Removed] ! Remove `PicoExcerpt` plugin
+* [Removed] Remove `rewrite_url` and `is_front_page` Twig variables
+* [Removed] Remove superfluous parameters of various events to reduce Pico's
+            error-proneness (plugins hopefully interfere with each other less)

+Contributing to Pico
+====================
+
+Pico aims to be a high quality Content Management System (CMS) but at the same time wants to give contributors freedom when submitting fixes or improvements.
+
+By contributing to Pico, you accept and agree to the *Developer Certificate of Origin* for your present and future contributions submitted to Pico. Please refer to the *Developer Certificate of Origin* section below.
+
+Aside from this, we want to *encourage*, but not obligate you, the contributor, to follow the following guidelines. The only exception to this are the guidelines elucidated in the *Prevent `merge-hell`* section. Having said that: we really appreciate it when you apply the guidelines in part or wholly as that will save us time which, in turn, we can spend on bugfixes and new features.
+
+Issues
+------
+
+If you want to report an *issue* with Pico's core, please create a new [Issue](https://github.com/picocms/Pico/issues) on GitHub. Concerning problems with plugins or themes, please refer to the website of the developer of this plugin or theme.
+
+Before creating a [new Issue on GitHub](https://github.com/picocms/Pico/issues/new), please make sure the problem wasn't reported yet using [GitHubs search engine](https://github.com/picocms/Pico/search?type=Issues).
+
+Please describe your issue as clear as possible and always include the *Pico version* you're using. Provided that you're using *plugins*, include a list of them too. We need information about the *actual and expected behavior*, the *steps to reproduce* the problem, and what steps you have taken to resolve the problem by yourself (i.e. *your own troubleshooting*).
+
+Contributing
+------------
+
+Once you decide you want to contribute to *Pico's core* (which we really appreciate!) you can fork the project from https://github.com/picocms/Pico. If you're interested in developing a *plugin* or *theme* for Pico, please refer to the [development section](http://picocms.org/development/) of our website.

+```
+
+Please note that developing a *plugin* or *theme* for Pico is *not* assumed to be a contribution to Pico itself. By developing a plugin or theme you rather create a 3rd-party project that just uses Pico. Following the spirit of open source, we want to *encourage* you to release your plugin or theme under the terms of a [OSI-approved open source license](https://opensource.org/licenses). After all, Pico is open source, too!
+
+### Prevent `merge-hell`
+
+Please do *not* develop your contribution on the `master` branch of your fork, but create a separate feature branch, that is based off the `master` branch, for each feature that you want to contribute.
+
+> Not doing so means that if you decide to work on two separate features and place a pull request for one of them, that the changes of the other issue that you are working on is also submitted. Even if it is not completely finished.
+
+To get more information about the usage of Git, please refer to the [Pro Git book](https://git-scm.com/book) written by Scott Chacon and/or [this help page of GitHub](https://help.github.com/articles/using-pull-requests).
+
+### Pull Requests
+
+Please keep in mind that pull requests should be small (i.e. one feature per request), stick to existing coding conventions and documentation should be updated if required. It's encouraged to make commits of logical units and check for unnecessary whitespace before committing (try `git diff --check`). Please reference issue numbers in your commit messages where appropriate.
+
+### Coding Standards
+
+Pico uses the [PSR-2 Coding Standard](http://www.php-fig.org/psr/psr-2/) as defined by the [PHP Framework Interoperability Group (PHP-FIG)](http://www.php-fig.org/).
+
+For historical reasons we don't use formal namespaces. Markdown files in the `content-sample` folder (the inline documentation) must follow a hard limit of 80 characters line length.
+
+It is recommended to check your code using [PHP_CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer) using Pico's `.phpcs.xml` standard. Use the following command:
+
+    $ ./vendor/bin/phpcs --standard=.phpcs.xml [file]...
+
+With this command you can specify a file or folder to limit which files it will check or omit that argument altogether, in which case the current working directory is checked.
+
+### Keep documentation in sync
+
+Pico accepts the problems of having redundant documentation on different places (concretely Pico's inline user docs, the `README.md` and the website) for the sake of a better user experience. When updating the docs, please make sure to keep them in sync.
+
+If you update the [`README.md`](https://github.com/picocms/Pico/blob/master/README.md) or [`content-sample/index.md`](https://github.com/picocms/Pico/blob/master/content-sample/index.md), please make sure to update the corresponding files in the [`_docs`](https://github.com/picocms/picocms.github.io/tree/master/_docs/) folder of the `picocms.github.io` repo (i.e. [Pico's website](http://picocms.org/docs/)) and vice versa. Unfortunately this involves three (!) different markdown parsers. If you're experiencing problems, use Pico's [`erusev/parsedown-extra`](https://github.com/erusev/parsedown-extra) as a reference. You can try to make the contents compatible to [Kramdown](http://kramdown.gettalong.org/) (Pico's website) and [CommonMarker](https://github.com/gjtorikian/commonmarker) (`README.md`) by yourself, otherwise please address the issues in your pull request message and we'll take care of it.
+
+Versioning
+----------
+
+Pico follows [Semantic Versioning 2.0](http://semver.org) and uses version numbers like `MAJOR`.`MINOR`.`PATCH`. We will increment the:
+
+- `MAJOR` version when we make incompatible API changes,
+- `MINOR` version when we add functionality in a backwards-compatible manner, and
+- `PATCH` version when we make backwards-compatible bug fixes.
+
+For more information please refer to the http://semver.org website.
+
+Branching
+---------
+
+The `master` branch contains the current development version of Pico. It is likely *unstable* and *not ready for production use*.
+
+However, the `master` branch always consists of a deployable (but not necessarily deployed) version of Pico. As soon as development of a new `MAJOR` or `MINOR` release starts, a separate branch (e.g. `pico-1.1`) is created and a [pull request](https://github.com/picocms/Pico/pulls) is opened to receive the desired feedback.
+
+Pico's actual development happens in separate development branches. Development branches are prefixed by:
+
+- `feature/` for bigger features,
+- `enhancement/` for smaller improvements, and
+- `bugfix/` for non-trivial bug fixes.
+
+As soon as development reaches a point where feedback is appreciated, a pull request is opened. After some time (very soon for bug fixes, and other improvements should have a reasonable feedback phase) the pull request is merged and the development branch will be deleted. Trivial bug fixes that will be part of the next `PATCH` version will be merged directly into `master`.
+
+Build & Release process
+-----------------------
+
+We're using [Travis CI](https://travis-ci.com) to automate the build & release process of Pico. It generates and deploys a [PHP class documentation](http://picocms.org/phpDoc/) (powered by [phpDoc](http://phpdoc.org)) for new releases and on every commit to the `master` branch. Travis also prepares new releases by generating Pico's pre-built release packages, a version badge, code statistics (powered by [cloc](https://github.com/AlDanial/cloc)) and updates our website (the [`picocms.github.io` repo](https://github.com/picocms/picocms.github.io)). Please refer to our [`.travis.yml`](https://github.com/picocms/Pico/blob/master/.travis.yml), the [`picocms/ci-tools` repo](https://github.com/picocms/ci-tools) and the [`.build` directory](https://github.com/picocms/Pico/tree/master/.build) for details.
+
+As insinuated above, it is important that each commit to `master` is deployable. Once development of a new Pico release is finished, trigger Pico's build & release process by pushing a new Git tag. This tag should reference a (usually empty) commit on `master`, which message should adhere to the following template:
+
+```
+Version 1.0.0
+
+* [Security] ...
+* [New] ...
+* [Changed] ...
+* [Fixed] ...
+* [Removed] ...
+```
+
+Before pushing a new Git tag, make sure to update the `Pico::VERSION` and `Pico::VERSION_ID` constants. The versions of Pico's official [default theme](https://github.com/picocms/pico-theme) and the [`PicoDeprecated` plugin](https://github.com/picocms/pico-deprecated) both strictly follow Pico's version. Since Pico's pre-built release package contains them, you must always create a new release of them (even though nothing has changed) before creating a new Pico release.
+
+If you're pushing a new major or minor release of Pico, you should also update Pico's `composer.json` to require the latest minor releases of Pico's dependencies. Besides, don't forget to update the `@version` tags in the PHP class docs.
+
+Travis CI will draft the new [release on GitHub](https://github.com/picocms/Pico/releases) automatically, but will require you to manually amend the descriptions formatting. The latest Pico version is always available at https://github.com/picocms/Pico/releases/latest, so please make sure to publish this URL rather than version-specific URLs. [Packagist](http://packagist.org/packages/picocms/pico) will be updated automatically.
+
+Labeling of Issues & Pull Requests
+----------------------------------
+
+Pico makes use of GitHub's label and milestone features, to aide developers in quickly identifying and prioritizing which issues need to be worked on. The starting point for labeling issues and pull requests is the `type` label, which is explained in greater detail below. The `type` label might get combined with a `pri` label, describing the issue's priority, and a `status` label, describing the current status of the issue.
+
+Issues and pull requests labeled with `info: Feedback Needed` indicate that feedback from others is highly appreciated. We always appreciate feedback at any time and from anyone, but when this label is present, we explicitly *ask* you to give feedback. It would be great if you leave a comment!
+
+- The `type: Bug` label is assigned to issues or pull requests, which have been identified as bugs or security issues in Pico's core. It might get combined with the `pri: High` label, when the problem was identified as security issue, or as a so-called "show stopper" bug. In contrast, uncritical problems might get labeled with `pri: Low`. `type: Bug` issues and pull requests are usually labeled with one of the following `status` labels when being closed:
+  - `status: Resolved` is used when the issue has been resolved.
+  - `status: Conflict` indicates a conflict with another issue or behavior of Pico, making it impossible to resolve the problem at the moment.
+  - `status: Won't Fix` means, that there is indeed a problem, but for some reason we made the decision that resolving it isn't reasonable, making it intended behavior.
+  - `status: Rejected` is used when the issue was rejected for another reason.
+
+- The `type: Enhancement` and `type: Feature` labels are used to tag pull requests, which introduce either a comparatively small enhancement, or a "big" new feature. As with the `type: Bug` label, they might get combined with the `pri: High` or `pri: Low` labels to indicate the pull request's priority. If a pull request isn't mergeable at the moment, it is labeled with `status: Work In Progress` until development of the pull request is finished. After merging or closing the pull request, it is labeled with one of the `status` labels as described above for the `type: Bug` label.
+
+- The `type: Idea` label is similar to the `type: Enhancement` and `type: Feature` labels, but is used for issues or incomplete and abandoned pull requests. It is otherwise used in the exact same way as `type: Enhancement` and `type: Feature`.
+
+- The `type: Release` label is used in the exact same way as `type: Feature` and indicates the primary pull request of a new Pico release (please refer to the *Branching* and *Build & Release process* sections above).
+
+- The `type: Notice`, `type: Support` and `type: Discussion` labels are used to indicate "fyi" issues, support-related issues (e.g. issues opened by users or developers asking questions), and issues with disucssions about arbitrary topics related to Pico. They are neither combined with `pri` labels, nor with `status` labels.
+
+- The `type: Duplicate` label is used when there is already another issue or pull request related to this problem or feature request. Issues labeled with `type: Duplicate` are immediately closed.
+
+- The `type: Invalid` label is used for everything else, e.g. issues or pull requests not related to Pico, or invalid bug reports. This includes supposed bug reports that concern actually intended behavior.
+
+The `status: Deferred` label might get added to any open issue or pull request to indicate that it is still unresolved and will be resolved later. This is also true for the `info: Pinned` label: It indicates a important issue or pull request that remains open on purpose.
+
+After resolving a issue, we usually keep it open for about a week to give users some more time for feedback and further questions. This is especially true for issues with the `type: Notice`, `type: Support`, `type: Discussion` and `type: Invalid` labels. After 7 days with no interaction, [Probot](https://probot.github.io/)'s [Stale](https://github.com/apps/stale) bot adds the `info: Stale` label to the issue to ask the participants whether the issue has been resolved. If no more activity occurs, the issue will be automatically closed by Stale bot 2 days later.

+Issues and pull requests labeled with `info: Information Needed` indicate that we have asked one of the participants for further information and didn't receive any feedback yet.

Issues labeled with `info: Website` are related to [Pico's website](http://picocms.org), however, in this case it is usually expedient to move the issue to the [`picocms.github.io` repo](https://github.com/picocms/picocms.github.io) instead. The same applies to the `info: Pico CMS for Nextcloud` label; these issues are related to [Pico CMS for Nextcloud](https://apps.nextcloud.com/apps/cms_pico).

+### PHP 8.0+ Users
+
+Seeing an `Unparenthesized a ? b : c ? d : e is not supported.` error?
+
+Pico currently has issues with PHP versions newer than 8.0.  This is due to Pico's dependencies, and not Pico itself.  There's currently an "alpha" build of Pico you can download as a [Pre-Bundled Release](https://github.com/picocms/Pico/releases/tag/v3.0.0-alpha.2) that solves this issue.
+
+This "alpha" is **perfectly safe** to use in production, as the *only* changes are **updated dependencies and version number strings**.  If you're curious, you can confirm this by [comparing the changes](https://github.com/picocms/Pico/compare/pico-3.0-alpha) between branches.
+
+More work was intended to be done on this branch, hence the "3.0" label, but it hasn't happened yet.  There's an [on-going discussion](https://github.com/picocms/Pico/issues/608) about getting just these updated dependencies merged in as an official update (either Pico 2.2 or 3.0) as soon as possible.
+
+Sorry for the inconvenience, and thanks to all Pico users for your patience on the matter. ❤️

+
+Install
+-------
+
+Installing Pico is dead simple - and done in seconds! If you have access to a shell on your server (i.e. SSH access), we recommend using [Composer][]. If not, use a pre-bundled release. If you don't know what "SSH access" is, head over to the pre-bundled release. 😇
+
+Pico requires PHP 5.3.6+ and the PHP extensions `dom` and `mbstring` to be enabled.
+
+### I want to use Composer
+
+Starting with Pico 2.0 we recommend installing Pico using Composer whenever possible. Trust us, you won't regret it when it comes to upgrading Pico! Anyway, if you don't want to use Composer, or if you simply can't use Composer because you don't have access to a shell on your server, don't despair, installing Pico using a pre-bundled release is still easier than everything you know!
+
+###### Step 1
+
+Open a shell and navigate to the `httpdocs` directory (e.g. `/var/www/html`) of your server. Download Composer and run it with the `create-project` option to install it to the desired directory (e.g. `/var/www/html/pico`):
+
+```shell
+$ curl -sSL https://getcomposer.org/installer | php
+$ php composer.phar create-project picocms/pico-composer pico
+```
+
+###### Step 2
+
+What second step? There's no second step. That's it! Open your favorite web browser and navigate to your brand new, stupidly simple, blazing fast, flat file CMS! Pico's sample contents will explain how to create your own contents. 😊
+
+### I want to use a pre-bundled release
+
+Do you know the feeling: You want to install a new website, so you upload all files of your favorite CMS and run the setup script - just to find out that you forgot about creating the SQL database first? Later the setup script tells you that the file permissions are wrong. Heck, what does this even mean? Forget about it, Pico is different!
+
+###### Step 1
+
+[Download the latest Pico release][LatestRelease] and upload all files to the desired install directory of Pico within the `httpdocs` directory (e.g. `/var/www/html/pico`) of your server.
+
+###### Step 2
+
+Okay, here's the catch: There's no catch. That's it! Open your favorite web browser and navigate to your brand new, stupidly simple, blazing fast, flat file CMS! Pico's sample contents will explain how to create your own contents. 😊
+
+### I want to manage my website using a Git repository
+
+Git is a very powerful distributed version-control system - and it can be used to establish a nice workflow around your Pico website. Using a Git repository for your website aids content creation and deployment, including collaborative editing and version control. If you want to manage your website in a Git repository, you use a Composer-based installation.
+
+1. Fork [Pico's Composer starter project][PicoComposerGit] using [GitHub's fork button][HelpFork]. If you don't want to use GitHub you aren't required to, you can choose whatever Git server you want. Forking manually just requires some extra steps: First clone the Git repository locally, add your Git server as a remote and push the repository to this new remote.
+
+2. Clone your fork locally and add your contents and assets. You can edit Pico's `composer.json` to include 3rd-party plugins and themes, or simply add your own plugins and themes to Pico's `plugins` resp. `themes` directories. Don't forget to commit your changes and push them to your Git server.
+
+3. Open a shell on your webserver and navigate to the `httpdocs` directory (e.g. `/var/www/html`). Download Composer, clone your Git repository to the desired directory (e.g. `/var/www/html/pico`) and install Pico's dependencies using Composer's `install` option:
+
+    ```shell
+    $ curl -sSL https://getcomposer.org/installer | php
+    $ git clone https://github.com/<YOUR_USERNAME>/<YOUR_REPOSITORY> pico
+    $ php composer.phar --working-dir=pico install
+    ```
+
+4. If you update your website's contents, simply commit your changes and push them to your Git server. Open a shell on your webserver and navigate to Pico's install directory within the `httpdocs` directory (e.g. `/var/www/html/pico`) of your server. Pull all changes from your Git server and update Pico's dependencies using Composer's `update` option:
+
+    ```shell
+    $ git pull
+    $ php composer.phar update
+    ```
+
+### I'm a developer
+
+So, you're one of these amazing people making all of this possible? We love you folks! As a developer we recommend you to clone [Pico's Git repository][PicoGit] as well as the Git repositories of [Pico's default theme][PicoThemeGit] and the [`PicoDeprecated` plugin][PicoDeprecatedGit]. You can set up your workspace using [Pico's Composer starter project][PicoComposerGit] and include all of Pico's components using local packages.
+
+Using Pico's Git repositories is different from using one of the installation methods elucidated above. It gives you the current development version of Pico, what is likely *unstable* and *not ready for production use*!
+
+1. Open a shell and navigate to the desired directory of Pico's development workspace within the `httpdocs` directory (e.g. `/var/www/html/pico`) of your server. Download and extract Pico's Composer starter project into the `workspace` directory:
+
+    ```shell
+    $ curl -sSL https://github.com/picocms/pico-composer/archive/master.tar.gz | tar xz
+    $ mv pico-composer-master workspace
+    ```
+
+2. Clone the Git repositories of all Pico components (Pico's core, Pico's default theme and the `PicoDeprecated` plugin) into the `components` directory:
+
+    ```shell
+    $ mkdir components
+    $ git clone https://github.com/picocms/Pico.git components/pico
+    $ git clone https://github.com/picocms/pico-theme.git components/pico-theme
+    $ git clone https://github.com/picocms/pico-deprecated.git components/pico-deprecated
+    ```
+
+3. Instruct Composer to use the local Git repositories as replacement for the `picocms/pico` (Pico's core), `picocms/pico-theme` (Pico's default theme) and `picocms/pico-deprecated` (the `PicoDeprecated` plugin) packages. Update the `composer.json` of your development workspace (i.e. `workspace/composer.json`) accordingly:
+
+    ```json
+    {
+        "repositories": [
+            {
+                "type": "path",
+                "url": "../components/pico",
+                "options": { "symlink": true }
+            },
+            {
+                "type": "path",
+                "url": "../components/pico-theme",
+                "options": { "symlink": true }
+            },
+            {
+                "type": "path",
+                "url": "../components/pico-deprecated",
+                "options": { "symlink": true }
+            }
+        ],
+        "require": {
+            "picocms/pico": "dev-master",
+            "picocms/pico-theme": "dev-master",
+            "picocms/pico-deprecated": "dev-master",
+            "picocms/composer-installer": "^1.0"
+        }
+    }
+    ```
+
+4. Download Composer and run it with the `install` option:
+
+    ```shell
+    $ curl -sSL https://getcomposer.org/installer | php
+    $ php composer.phar --working-dir=workspace install
+    ```
+
+You can now open your web browser and navigate to Pico's development workspace. All changes you make to Pico's components will automatically be reflected in the development workspace.
+
+By the way, you can also find all of Pico's components on [Packagist.org][Packagist]: [Pico's core][PicoPackagist], [Pico's default theme][PicoThemePackagist], the [`PicoDeprecated` plugin][PicoDeprecatedPackagist] and [Pico's Composer starter project][PicoComposerPackagist].
+
+Upgrade
+-------
+
+Do you remember when you installed Pico? It was ingeniously simple, wasn't it? Upgrading Pico is no difference! The upgrade process differs depending on whether you used [Composer][] or a pre-bundled release to install Pico. Please note that you should *always* create a backup of your Pico installation before upgrading!
+
+Pico follows [Semantic Versioning 2.0][SemVer] and uses version numbers like `MAJOR`.`MINOR`.`PATCH`. When we update the `PATCH` version (e.g. `2.0.0` to `2.0.1`), we made backwards-compatible bug fixes. If we change the `MINOR` version (e.g. `2.0` to `2.1`), we added functionality in a backwards-compatible manner. Upgrading Pico is dead simple in both cases. Simply head over to the appropiate Upgrade sections below.
+
+But wait, we forgot to mention what happens when we update the `MAJOR` version (e.g. `2.0` to `3.0`). In this case we made incompatible API changes. We will then provide a appropriate upgrade tutorial, so please head over to the ["Upgrade" page on our website][HelpUpgrade].
+
+### I've used Composer to install Pico
+
+Upgrading Pico is dead simple if you've used Composer to install Pico. Simply open a shell and navigate to Pico's install directory within the `httpdocs` directory (e.g. `/var/www/html/pico`) of your server. You can now upgrade Pico using just a single command:
+
+```shell
+$ php composer.phar update
+```
+
+That's it! Composer will automatically update Pico and all plugins and themes you've installed using Composer. Please make sure to manually update all plugins and themes you've installed manually.
+
+### I've used a pre-bundled release to install Pico
+
+Okay, installing Pico was easy, but upgrading Pico is going to be hard, isn't it? I'm afraid I have to disappoint you. It's just as simple as installing Pico!
+
+First you'll have to delete the `vendor` directory of your Pico installation (e.g. if you've installed Pico to `/var/www/html/pico`, delete `/var/www/html/pico/vendor`). Then [download the latest Pico release][LatestRelease] and upload all files to your existing Pico installation directory. You will be prompted whether you want to overwrite files like `index.php`, `.htaccess`, ... - simply hit "Yes".
+
+That's it! Now that Pico is up-to-date, you need to update all plugins and themes you've installed.
+
+### I'm a developer
+
+As a developer you should know how to stay up-to-date... 😉 For the sake of completeness, if you want to upgrade Pico, simply open a shell and navigate to Pico's development workspace (e.g. `/var/www/html/pico`). Then pull the latest commits from the Git repositories of [Pico's core][PicoGit], [Pico's default theme][PicoThemeGit] and the [`PicoDeprecated` plugin][PicoDeprecatedGit]. Let Composer update your dependencies and you're ready to go.
+
+```shell
+$ git -C components/pico pull
+$ git -C components/pico-theme pull
+$ git -C components/pico-deprecated pull
+$ php composer.phar --working-dir=workspace update
+```
+

+
+#### You still need help or experience a problem with Pico?
+
+When the docs can't answer your question, you can get help by joining us on [#picocms on Libera.Chat][LiberaChat] ([logs][LiberaChatLogs]). When you're experiencing problems with Pico, please don't hesitate to create a new [Issue][Issues] on GitHub. Concerning problems with plugins or themes, please refer to the website of the developer of this plugin or theme.
+
+**Before creating a new Issue,** please make sure the problem wasn't reported yet using [GitHubs search engine][IssuesSearch]. Please describe your issue as clear as possible and always include the *Pico version* you're using. Provided that you're using *plugins*, include a list of them too. We need information about the *actual and expected behavior*, the *steps to reproduce* the problem, and what steps you have taken to resolve the problem by yourself (i.e. *your own troubleshooting*).
+
+Contributing
+------------
+
+You want to contribute to Pico? We really appreciate that! You can help make Pico better by [contributing code][PullRequests] or [reporting issues][Issues], but please take note of our [contribution guidelines][ContributionGuidelines]. In general you can contribute in three different areas:
+
+1. Plugins & Themes: You're a plugin developer or theme designer? We love you folks! You can find tons of information about how to develop plugins and themes at http://picocms.org/development/. If you have created a plugin or theme, please add it to our [Wiki][], either on the [plugins][WikiPlugins] or [themes][WikiThemes] page. You may also [Submit][] it to our website, where it'll be displayed on the official [plugin][OfficialPlugins] or [theme][OfficialThemes] pages!
+
+2. Documentation: We always appreciate people improving our documentation. You can either improve the [inline user docs][EditInlineDocs] or the more extensive [user docs on our website][EditUserDocs]. You can also improve the [docs for plugin and theme developers][EditDevDocs]. Simply fork our website's Git repository from https://github.com/picocms/picocms.github.io, change the Markdown files and open a [pull request][PullRequestsWebsite].
+
+3. Pico's Core: The supreme discipline is to work on Pico's Core. Your contribution should help *every* Pico user to have a better experience with Pico. If this is the case, fork Pico from https://github.com/picocms/Pico and open a [pull request][PullRequests]. We look forward to your contribution!
+
+By contributing to Pico, you accept and agree to the *Developer Certificate of Origin* for your present and future contributions submitted to Pico. Please refer to the ["Developer Certificate of Origin" section in our `CONTRIBUTING.md`][ContributionGuidelinesDCO].
+
+You don't have time to contribute code to Pico, but still want to "stand a coffee" for the ones who do? You can contribute monetary to Pico using [Bountysource][], a crowd funding website that focuses on individual issues and feature requests. Just refer to the "Bounties and Fundraisers" section below for more info.
+
+Bounties and Fundraisers
+------------------------
+
+Pico uses [Bountysource][] to allow monetary contributions to the project. Bountysource is a crowd funding website that focuses on individual issues and feature requests in Open Source projects using micropayment. Users, or "Backers", can pledge money for fixing a specific issue, implementing new features, or developing a new plugin or theme. Open source software developers, or "Bounty Hunters", can then pick up and solve these tasks to earn the money.
+
+Obviously this won't allow a developer to replace a full time job, it's rather aiming to "stand a coffee". However, it helps bringing users and developers closer together, and shows developers what users want and how much they care about certain things. Nevertheless you can still donate money to the project itself, as an easy way to say "Thank You" and to support Pico.
+
+If you want to encourage developers to [fix a specific issue][Issues] or implement a feature, simply [pledge a new bounty][Bountysource] or back an existing one.
+
+As a developer you can pick up a bounty by simply contributing to Pico (please refer to the "Contributing" section above). You don't have to be a official Pico Contributor! Pico is a Open Source project, anyone can open [pull requests][PullRequests] and claim bounties.
+
+Official Pico Contributors won't claim bounties on their own behalf, Pico will never take any money out of Bountysource. All money collected by Pico is used to pledge new bounties or to support projects Pico depends on.

+Title: Welcome
+Description: Pico is a stupidly simple, blazing fast, flat file CMS.
+---
+
+## Welcome to Pico
+
+Congratulations, you have successfully installed [Pico][] %version%.
+%meta.description% <!-- replaced by the above Description header -->
+
+## Creating Content
+
+Pico is a flat file CMS. This means there is no administration backend or
+database to deal with. You simply create `.md` files in the `content` folder
+and those files become your pages. For example, this file is called `index.md`
+and is shown as the main landing page.
+
+When you install Pico, it comes with some sample contents that will display
+until you add your own content. Simply add some `.md` files to your `content`
+folder in Pico's root directory. No configuration is required, Pico will
+automatically use the `content` folder as soon as you create your own
+`index.md`. Just check out [Pico's sample contents][SampleContents] for an
+example!
+
+If you create a folder within the content directory (e.g. `content/sub`) and
+put an `index.md` inside it, you can access that folder at the URL
+`%base_url%?sub`. If you want another page within the sub folder, simply create
+a text file with the corresponding name and you will be able to access it
+(e.g. `content/sub/page.md` is accessible from the URL `%base_url%?sub/page`).
+Below we've shown some examples of locations and their corresponding URLs:
+
+<table style="width: 100%; max-width: 40em;">
+    <thead>
+        <tr>
+            <th style="width: 50%;">Physical Location</th>
+            <th style="width: 50%;">URL</th>
+        </tr>
+    </thead>
+    <tbody>
+        <tr>
+            <td>content/index.md</td>
+            <td><a href="%base_url%">/</a></td>
+        </tr>
+        <tr>
+            <td>content/sub.md</td>
+            <td><del>?sub</del> (not accessible, see below)</td>
+        </tr>
+        <tr>
+            <td>content/sub/index.md</td>
+            <td><a href="%base_url%?sub">?sub</a> (same as above)</td>
+        </tr>
+        <tr>
+            <td>content/sub/page.md</td>
+            <td><a href="%base_url%?sub/page">?sub/page</a></td>
+        </tr>
+        <tr>
+            <td>content/theme.md</td>
+            <td><a href="%base_url%?theme">?theme</a> (hidden in menu)</td>
+        </tr>
+        <tr>
+            <td>content/a/very/long/url.md</td>
+            <td>
+              <a href="%base_url%?a/very/long/url">?a/very/long/url</a>
+              (doesn't exist)
+            </td>
+        </tr>
+    </tbody>
+</table>
+
+If a file cannot be found, the file `content/404.md` will be shown. You can add
+`404.md` files to any directory. So, for example, if you wanted to use a special
+error page for your blog, you could simply create `content/blog/404.md`.
+
+Pico strictly separates contents of your website (the Markdown files in your
+`content` directory) and how these contents should be displayed (the Twig
+templates in your `themes` directory). However, not every file in your `content`
+directory might actually be a distinct page. For example, some themes (including
+Pico's default theme) use some special "hidden" file to manage meta data (like
+`_meta.md` in Pico's sample contents). Some other themes use a `_footer.md` to
+represent the contents of the website's footer. The common point is the `_`: all
+files and directories prefixed by a `_` in your `content` directory are hidden.
+These pages can't be accessed from a web browser, Pico will show a 404 error
+page instead.
+
+As a common practice, we recommend you to separate your contents and assets
+(like images, downloads, etc.). We even deny access to your `content` directory
+by default. If you want to use some assets (e.g. a image) in one of your content
+files, use Pico's `assets` folder. You can then access them in your Markdown
+using the <code>&#37;assets_url&#37;</code> placeholder, for example:
+<code>!\[Image Title\](&#37;assets_url&#37;/image.png)</code>
+
+### Text File Markup
+
+Text files are marked up using [Markdown][] and [Markdown Extra][MarkdownExtra].
+They can also contain regular HTML.
+
+At the top of text files you can place a block comment and specify certain meta
+attributes of the page using [YAML][] (the "YAML header"). For example:
+
+    ---
+    Title: Welcome
+    Description: This description will go in the meta description tag
+    Author: Joe Bloggs
+    Date: 2001-04-25
+    Robots: noindex,nofollow
+    Template: index
+    ---
+
+These values will be contained in the `{{ meta }}` variable in themes (see
+below). Meta headers sometimes have a special meaning: For instance, Pico not
+only passes through the `Date` meta header, but rather evaluates it to really
+"understand" when this page was created. This comes into play when you want to
+sort your pages not just alphabetically, but by date. Another example is the
+`Template` meta header: It controls what Twig template Pico uses to display
+this page (e.g. if you add `Template: blog`, Pico uses `blog.twig`).
+
+In an attempt to separate contents and styling, we recommend you to not use
+inline CSS in your Markdown files. You should rather add appropriate CSS
+classes to your theme. For example, you might want to add some CSS classes to
+your theme to rule how much of the available space a image should use (e.g.
+`img.small { width: 80%; }`). You can then use these CSS classes in your
+Markdown files, for example:
+<code>!\[Image Title\](&#37;assets_url&#37;/image.png) {.small}</code>
+
+There are also certain variables that you can use in your text files:
+
+* <code>&#37;site_title&#37;</code> - The title of your Pico site
+* <code>&#37;base_url&#37;</code> - The URL to your Pico site; internal links
+  can be specified using <code>&#37;base_url&#37;?sub/page</code>
+* <code>&#37;theme_url&#37;</code> - The URL to the currently used theme
+* <code>&#37;assets_url&#37;</code> - The URL to Pico's `assets` directory
+* <code>&#37;themes_url&#37;</code> - The URL to Pico's `themes` directory;
+  don't confuse this with <code>&#37;theme_url&#37;</code>
+* <code>&#37;plugins_url&#37;</code> - The URL to Pico's `plugins` directory
+* <code>&#37;version&#37;</code> - Pico's current version string (e.g. `2.0.0`)
+* <code>&#37;meta.&#42;&#37;</code> - Access any meta variable of the current
+  page, e.g. <code>&#37;meta.author&#37;</code> is replaced with `Joe Bloggs`
+* <code>&#37;config.&#42;&#37;</code> - Access any scalar config variable,
+  e.g. <code>&#37;config.theme&#37;</code> is replaced with `default`
+
+### Blogging
+
+Pico is not blogging software - but makes it very easy for you to use it as a
+blog. You can find many plugins out there implementing typical blogging
+features like authentication, tagging, pagination and social plugins. See the
+below Plugins section for details.
+
+If you want to use Pico as a blogging software, you probably want to do
+something like the following:
+
+1. Put all your blog articles in a separate `blog` folder in your `content`
+   directory. All these articles should have a `Date` meta header.
+2. Create a `blog.md` or `blog/index.md` in your `content` directory. Add
+   `Template: blog-index` to the YAML header of this page. It will later show a
+   list of all your blog articles (see step 3).
+3. Create the new Twig template `blog-index.twig` (the file name must match the
+   `Template` meta header from Step 2) in your theme directory. This template
+   probably isn't very different from your default `index.twig` (i.e. copy
+   `index.twig`), it will create a list of all your blog articles. Add the
+   following Twig snippet to `blog-index.twig` near `{{ content }}`:
+   ```
+    {% for page in pages("blog")|sort_by("time")|reverse if not page.hidden %}
+        <div class="post">
+            <h3><a href="{{ page.url }}">{{ page.title }}</a></h3>
+            <p class="date">{{ page.date_formatted }}</p>
+            <p class="excerpt">{{ page.description }}</p>
+        </div>
+    {% endfor %}
+   ```
+
+## Customization
+
+Pico is highly customizable in two different ways: On the one hand you can
+change Pico's appearance by using themes, on the other hand you can add new
+functionality by using plugins. Doing the former includes changing Pico's HTML,
+CSS and JavaScript, the latter mostly consists of PHP programming.
+
+This is all Greek to you? Don't worry, you don't have to spend time on these
+techie talk - it's very easy to use one of the great themes or plugins others
+developed and released to the public. Please refer to the next sections for
+details.
+
+### Themes
+
+You can create themes for your Pico installation in the `themes` folder. Pico
+uses [Twig][] for template rendering. You can select your theme by setting the
+`theme` option in `config/config.yml` to the name of your theme folder.
+
+[Pico's default theme][PicoTheme] isn't really intended to be used for a
+productive website, it's rather a starting point for creating your own theme.
+If the default theme isn't sufficient for you, and you don't want to create
+your own theme, you can use one of the great themes third-party developers and
+designers created in the past. As with plugins, you can find themes on [our website][OfficialThemes].
+
+All themes must include an `index.twig` file to define the HTML structure of
+the theme, and a `pico-theme.yml` to set the necessary config parameters. Just
+refer to Pico's default theme as an example. You can use different templates
+for different content files by specifying the `Template` meta header. Simply
+add e.g. `Template: blog` to the YAML header of a content file and Pico will
+use the `blog.twig` template in your theme folder to display the page.
+
+Below are the Twig variables that are available to use in themes. Please note
+that URLs (e.g. `{{ base_url }}`) never include a trailing slash.
+
+* `{{ site_title }}` - Shortcut to the site title (see `config/config.yml`)
+* `{{ config }}` - Contains the values you set in `config/config.yml`
+                   (e.g. `{{ config.theme }}` becomes `default`)
+* `{{ base_url }}` - The URL to your Pico site; use Twig's `link` filter to
+                     specify internal links (e.g. `{{ "sub/page"|link }}`),
+                     this guarantees that your link works whether URL rewriting
+                     is enabled or not
+* `{{ theme_url }}` - The URL to the currently active theme
+* `{{ assets_url }}` - The URL to Pico's `assets` directory
+* `{{ themes_url }}` - The URL to Pico's `themes` directory; don't confuse this
+                       with `{{ theme_url }}`
+* `{{ plugins_url }}` - The URL to Pico's `plugins` directory
+* `{{ version }}` - Pico's current version string (e.g. `%version%`)
+* `{{ meta }}` - Contains the meta values of the current page
+    * `{{ meta.title }}` - The `Title` YAML header
+    * `{{ meta.description }}` - The `Description` YAML header
+    * `{{ meta.author }}` - The `Author` YAML header
+    * `{{ meta.date }}` - The `Date` YAML header
+    * `{{ meta.date_formatted }}` - The formatted date of the page as specified
+                                    by the `date_format` parameter in your
+                                    `config/config.yml`
+    * `{{ meta.time }}` - The [Unix timestamp][UnixTimestamp] derived from the
+                          `Date` YAML header
+    * `{{ meta.robots }}` - The `Robots` YAML header
+    * ...
+* `{{ content }}` - The content of the current page after it has been processed
+                    through Markdown
+* `{{ previous_page }}` - The data of the previous page, relative to
+                          `current_page`
+* `{{ current_page }}` - The data of the current page; refer to the "Pages"
+                         section below for details
+* `{{ next_page }}` - The data of the next page, relative to `current_page`
+
+To call assets from your theme, use `{{ theme_url }}`. For instance, to include
+the CSS file `themes/my_theme/example.css`, add
+`<link rel="stylesheet" href="{{ theme_url }}/example.css" type="text/css" />`
+to your `index.twig`. This works for arbitrary files in your theme's folder,
+including images and JavaScript files.
+
+Please note that Twig escapes HTML in all strings before outputting them. So
+for example, if you add `headline: My <strong>favorite</strong> color` to the
+YAML header of a page and output it using `{{ meta.headline }}`, you'll end up
+seeing `My <strong>favorite</strong> color` - yes, including the markup! To
+actually get it parsed, you must use `{{ meta.headline|raw }}` (resulting in
+the expected <code>My **favorite** color</code>). Notable exceptions to this
+are Pico's `content` variable (e.g. `{{ content }}`), Pico's `content` filter
+(e.g. `{{ "sub/page"|content }}`), and Pico's `markdown` filter, they all are
+marked as HTML safe.
+
+#### Dealing with pages
+
+There are several ways to access Pico's pages list. You can access the current
+page's data using the `current_page` variable, or use the `prev_page` and/or
+`next_page` variables to access the respective previous/next page in Pico's
+pages list. But more importantly there's the `pages()` function. No matter how
+you access a page, it will always consist of the following data:
+
+* `{{ id }}` - The relative path to the content file (unique ID)
+* `{{ url }}` - The URL to the page
+* `{{ title }}` - The title of the page (`Title` YAML header)
+* `{{ description }}` - The description of the page (`Description` YAML header)
+* `{{ author }}` - The author of the page (`Author` YAML header)
+* `{{ date }}` - The date of the page (`Date` YAML header)
+* `{{ date_formatted }}` - The formatted date of the page as specified by the
+                           `date_format` parameter in your `config/config.yml`
+* `{{ time }}` - The [Unix timestamp][UnixTimestamp] derived from the page's
+                 date
+* `{{ raw_content }}` - The raw, not yet parsed contents of the page; use the
+                        filter to get the parsed contents of a page by passing
+                        its unique ID (e.g. `{{ "sub/page"|content }}`)
+* `{{ meta }}` - The meta values of the page (see global `{{ meta }}` above)
+* `{{ prev_page }}` - The data of the respective previous page
+* `{{ next_page }}` - The data of the respective next page
+* `{{ tree_node }}` - The page's node in Pico's page tree; check out Pico's
+                      [page tree documentation][FeaturesPageTree] for details
+
+Pico's `pages()` function is the best way to access all of your site's pages.
+It uses Pico's page tree to easily traverse a subset of Pico's pages list. It
+allows you to filter pages and to build recursive menus (like dropdowns). By
+default, `pages()` returns a list of all main pages (e.g. `content/page.md` and
+`content/sub/index.md`, but not `content/sub/page.md` or `content/index.md`).
+If you want to return all pages below a specific folder (e.g. `content/blog/`),
+pass the folder name as first parameter to the function (e.g. `pages("blog")`).
+Naturally you can also pass variables to the function. For example, to return a
+list of all child pages of the current page, use `pages(current_page.id)`.
+Check out the following code snippet:
+
+    <section class="articles">
+        {% for page in pages(current_page.id) if not page.hidden %}
+            <article>
+                <h2><a href="{{ page.url }}">{{ page.title }}</a></h2>
+                {{ page.id|content }}
+            </article>
+        {% endfor %}
+    </section>
+
+The `pages()` function is very powerful and also allows you to return not just
+a page's child pages by passing the `depth` and `depthOffset` params. For
+example, if you pass `pages(depthOffset=-1)`, the list will also include Pico's
+main index page (i.e. `content/index.md`). This one is commonly used to create
+a theme's main navigation. If you want to learn more, head over to Pico's
+complete [`pages()` function documentation][FeaturesPagesFunction].
+
+If you want to access the data of a particular page, use Pico's `pages`
+variable. Just take `content/_meta.md` in Pico's sample contents for an
+example: `content/_meta.md` contains some meta data you might want to use in
+your theme. If you want to output the page's `tagline` meta value, use
+`{{ pages["_meta"].meta.logo }}`. Don't ever try to use Pico's `pages` variable
+as an replacement for Pico's `pages()` function. Its usage looks very similar,
+it will kinda work and you might even see it being used in old themes, but be
+warned: It slows down Pico. Always use Pico's `pages()` function when iterating
+Pico's page list (e.g. `{% for page in pages() %}…{% endfor %}`).
+
+#### Twig filters and functions
+
+Additional to [Twig][]'s extensive list of filters, functions and tags, Pico
+also provides some useful additional filters and functions to make theming
+even easier.
+
+* Pass the unique ID of a page to the `link` filter to return the page's URL
+  (e.g. `{{ "sub/page"|link }}` gets `%base_url%?sub/page`).
+* You can replace URL placeholders (like <code>&#37;base_url&#37;</code>) in
+  arbitrary strings using the `url` filter. This is helpful together with meta
+  variables, e.g. if you add <code>image: &#37;assets_url&#37;/stock.jpg</code>
+  to the YAML header of a page, `{{ meta.image|url }}` will return
+  `%assets_url%/stock.jpg`.
+* To get the parsed contents of a page, pass its unique ID to the `content`
+  filter (e.g. `{{ "sub/page"|content }}`).
+* You can parse any Markdown string using the `markdown` filter. For example,
+  you might use Markdown in the `description` meta variable and later parse it
+  in your theme using `{{ meta.description|markdown }}`. You can also pass meta
+  data as parameter to replace <code>&#37;meta.&#42;&#37;</code> placeholders
+  (e.g. `{{ "Written by *%meta.author%*"|markdown(meta) }}` yields "Written by
+  *John Doe*"). However, please note that all contents will be wrapped inside
+  HTML paragraph elements (i.e. `<p>…</p>`). If you want to parse just a single
+  line of Markdown markup, pass the `singleLine` param to the `markdown` filter
+  (e.g. `{{ "This really is a *single* line"|markdown(singleLine=true) }}`).
+* Arrays can be sorted by one of its keys using the `sort_by` filter
+  (e.g. `{% for page in pages|sort_by([ 'meta', 'nav' ]) %}...{% endfor %}`
+  iterates through all pages, ordered by the `nav` meta header; please note the
+  `[ 'meta', 'nav' ]` part of the example, it instructs Pico to sort by
+  `page.meta.nav`). Items which couldn't be sorted are moved to the bottom of
+  the array; you can specify `bottom` (move items to bottom; default), `top`
+  (move items to top), `keep` (keep original order) or `remove` (remove items)
+  as second parameter to change this behavior.
+* You can return all values of a given array key using the `map` filter
+  (e.g. `{{ pages|map("title") }}` returns all page titles).
+* Use the `url_param` and `form_param` Twig functions to access HTTP GET (i.e.
+  a URL's query string like `?some-variable=my-value`) and HTTP POST (i.e. data
+  of a submitted form) parameters. This allows you to implement things like
+  pagination, tags and categories, dynamic pages, and even more - with pure
+  Twig! Simply head over to our [introductory page for accessing HTTP
+  parameters][FeaturesHttpParams] for details.
+
+### Plugins
+
+#### Plugins for users
+
+Officially tested plugins can be found at http://picocms.org/plugins/, but
+there are many awesome third-party plugins out there! A good start point for
+discovery is [our Wiki][WikiPlugins].
+
+Pico makes it very easy for you to add new features to your website using
+plugins. Just like Pico, you can install plugins either using [Composer][]
+(e.g. `composer require phrozenbyte/pico-file-prefixes`), or manually by
+uploading the plugin's file (just for small plugins consisting of a single file,
+e.g. `PicoFilePrefixes.php`) or directory (e.g. `PicoFilePrefixes`) to your
+`plugins` directory. We always recommend you to use Composer whenever possible,
+because it makes updating both Pico and your plugins way easier. Anyway,
+depending on the plugin you want to install, you may have to go through some
+more steps (e.g. specifying config variables) to make the plugin work. Thus you
+should always check out the plugin's docs or `README.md` file to learn the
+necessary steps.
+
+Plugins which were written to work with Pico 1.0 and later can be enabled and
+disabled through your `config/config.yml`. If you want to e.g. disable the
+`PicoDeprecated` plugin, add the following line to your `config/config.yml`:
+`PicoDeprecated.enabled: false`. To force the plugin to be enabled, replace
+`false` by `true`.
+
+#### Plugins for developers
+
+You're a plugin developer? We love you guys! You can find tons of information
+about how to develop plugins at http://picocms.org/development/. If you've
+developed a plugin before and want to upgrade it to Pico 2.0, refer to the
+[upgrade section of the docs][PluginUpgrade].
+
+## Config
+
+Configuring Pico really is stupidly simple: Just create a `config/config.yml`
+to override the default Pico settings (and add your own custom settings). Take
+a look at the `config/config.yml.template` for a brief overview of the
+available settings and their defaults. To override a setting, simply copy the
+line from `config/config.yml.template` to `config/config.yml` and set your
+custom value.
+
+But we didn't stop there. Rather than having just a single config file, you can
+use a arbitrary number of config files. Simply create a `.yml` file in Pico's
+`config` dir and you're good to go. This allows you to add some structure to
+your config, like a separate config file for your theme (`config/my_theme.yml`).
+
+Please note that Pico loads config files in a special way you should be aware
+of. First of all it loads the main config file `config/config.yml`, and then
+any other `*.yml` file in Pico's `config` dir in alphabetical order. The file
+order is crucial: Config values which have been set already, cannot be
+overwritten by a succeeding file. For example, if you set `site_title: Pico` in
+`config/a.yml` and `site_title: My awesome site!` in `config/b.yml`, your site
+title will be "Pico".
+
+Since YAML files are plain text files, users might read your Pico config by
+navigating to `%base_url%/config/config.yml`. This is no problem in the first
+place, but might get a problem if you use plugins that require you to store
+security-relevant data in the config (like credentials). Thus you should
+*always* make sure to configure your webserver to deny access to Pico's
+`config` dir. Just refer to the "URL Rewriting" section below. By following the
+instructions, you will not just enable URL rewriting, but also deny access to
+Pico's `config` dir.
+
+### URL Rewriting
+
+Pico's default URLs (e.g. %base_url%/?sub/page) already are very user-friendly.
+Additionally, Pico offers you a URL rewrite feature to make URLs even more
+user-friendly (e.g. %base_url%/sub/page). Below you'll find some basic info
+about how to configure your webserver proberly to enable URL rewriting.
+
+#### Apache
+
+If you're using the Apache web server, URL rewriting probably already is
+enabled - try it yourself, click on the [second URL](%base_url%/sub/page). If
+URL rewriting doesn't work (you're getting `404 Not Found` error messages from
+Apache), please make sure to enable the [`mod_rewrite` module][ModRewrite] and
+to enable `.htaccess` overrides. You might have to set the
+[`AllowOverride` directive][AllowOverride] to `AllowOverride All` in your
+virtual host config file or global `httpd.conf`/`apache.conf`. Assuming
+rewritten URLs work, but Pico still shows no rewritten URLs, force URL
+rewriting by setting `rewrite_url: true` in your `config/config.yml`. If you
+rather get a `500 Internal Server Error` no matter what you do, try removing
+the `Options` directive from Pico's `.htaccess` file (it's the last line).
+
+#### Nginx
+
+If you're using Nginx, you can use the following config to enable URL rewriting
+(lines `5` to `8`) and denying access to Pico's internal files (lines `1` to
+`3`). You'll need to adjust the path (`/pico` on lines `1`, `2`, `5` and `7`)
+to match your installation directory. Additionally, you'll need to enable URL
+rewriting by setting `rewrite_url: true` in your `config/config.yml`. The Nginx
+config should provide the *bare minimum* you need for Pico. Nginx is a very
+extensive subject. If you have any trouble, please read through our
+[Nginx config docs][NginxConfig].
+
+```
+location ~ ^/pico/((config|content|vendor|composer\.(json|lock|phar))(/|$)|(.+/)?\.(?!well-known(/|$))) {
+    try_files /pico/index.php$is_args$args =404;
+}
+
+location /pico/ {
+    index index.php;
+    try_files $uri $uri/ /pico/index.php$is_args$args;
+}
+```
+
+#### Lighttpd
+
+Pico runs smoothly on Lighttpd. You can use the following config to enable URL
+rewriting (lines `6` to `9`) and denying access to Pico's internal files (lines
+`1` to `4`). Make sure to adjust the path (`/pico` on lines `2`, `3` and `7`)
+to match your installation directory, and let Pico know about available URL
+rewriting by setting `rewrite_url: true` in your `config/config.yml`. The
+config below should provide the *bare minimum* you need for Pico.
+
+```
+url.rewrite-once = (
+    "^/pico/(config|content|vendor|composer\.(json|lock|phar))(/|$)" => "/pico/index.php",
+    "^/pico/(.+/)?\.(?!well-known(/|$))" => "/pico/index.php"
+)
+
+url.rewrite-if-not-file = (
+    "^/pico(/|$)" => "/pico/index.php"
+)
+```

-Title: Welcome
-Description: This description will go in the meta description tag

-
-Welcome to Pico
-===============
-
-Congratulations you have successfully installed [Pico](http://pico.dev7studios.com). Pico is a stupidly simple, blazing fast, flat file CMS.
-
-Creating Content
-----------------
-
-Pico is a flat file CMS, this means there is no administration backend and database to deal with. You simply create `.txt` files in the "content"
-folder and that becomes a page. For example this file is called `index.txt` and is shown as the main landing page. 
-
-If you created folder within the content folder (e.g. `content/sub`) and put an `index.txt` inside it, you can access that folder at the URL 
-`http://yousite.com/sub`. If you want another page within the sub folder, simply create a text file with the corresponding name (e.g. `content/sub/page.txt`)
-and will be able to access it from the URL `http://yousite.com/sub/page`. Below we've shown some examples of content locations and their corresponing URL's:
-
-<table>
-	<thead>
-		<tr><th>Physical Location</th><th>URL</th></tr>
-	</thead>
-	<tbody>
-		<tr><td>content/index.txt</td><td>/</td></tr>
-		<tr><td>content/sub.txt</td><td>/sub</td></tr>
-		<tr><td>content/sub/index.txt</td><td>/sub (same as above)</td></tr>
-		<tr><td>content/sub/page.txt</td><td>/sub/page</td></tr>
-		<tr><td>content/a/very/long/url.txt</td><td>/a/very/long/url</td></tr>
-	</tbody>
-</table>
-
-If a file cannot be found, the file `content/404.txt` will be shown.
-
-Text File Markup
-----------------
-
-Text files are marked up using [Markdown](http://daringfireball.net/projects/markdown/syntax). They can also contain regular HTML.
-
-At the top of text files you can place a block comment and specify certain attributes of the page. For example:
-
-	/ *
-	Title: Welcome
-	Description: This description will go in the meta description tag
-	Robots: noindex,nofollow
-	*/
-
-These values will be contained in the `{{ meta }}` variable in themes (see below).
-
-There are also certain variables that you can use in your text files:
-
-* &#37;base_url&#37; - The URL to your Pico site
-
-Themes
-------
-
-You can create themes for your Pico installation and in the "themes" folder. Check out the default theme for an example of a theme. Pico uses
-[Twig](http://twig.sensiolabs.org/documentation) for it's templating engine. You can select your theme by setting the `$config['theme']` variable
-in config.php to your theme folder.
-
-All themes must include an `index.html` file to define the HTML structure of the theme. Below are the Twig variables that are available to use in your theme:
-
-* `{{ config }}` - Conatins the values you set in config.php (e.g. `{{ config.theme }}` = "default")
-* `{{ base_dir }}` - The path to your Pico root directory
-* `{{ base_url }}` - The URL to your Pico site
-* `{{ theme_dir }}` - The path to the Pico active theme direcotry
-* `{{ theme_url }}` - The URL to the Pico active theme direcotry
-* `{{ site_title }}` - Shortcut to the site title (defined in config.php)
-* `{{ meta }}` - Contains the meta values from the current page (e.g. `{{ meta.title }}`, `{{ meta.description }}`, `{{ meta.robots }}`)
-* `{{ content }}` - The content of the current page (after it has been processed through Markdown)
-
-Config
-------
-
-You can override the default Pico settings (and add your own custom settings) by editing config.php in the root Pico directory. The config.php file
-list all of the settings and their defaults. To override a setting simply uncomment it in config.php and set your custom value.

+     * Returns all pages within a particular branch of Pico's page tree
+     *
+     * This function should be used most of the time when dealing with Pico's
+     * pages array, as it allows one to easily traverse Pico's pages tree
+     * ({@see Pico::getPageTree()}) to retrieve a subset of Pico's pages array
+     * in a very convenient and performant way.
+     *
+     * The function's default parameters are `$start = ""`, `$depth = 0`,
+     * `$depthOffset = 0` and `$offset = 1`. A positive `$offset` is equivalent
+     * to `$depth = $depth + $offset`, `$depthOffset = $depthOffset + $offset`
+     * and `$offset = 0`.
+     *
+     * Consequently the default `$start = ""`, `$depth = 0`, `$depthOffset = 0`
+     * and `$offset = 1` is equivalent to `$depth = 1`, `$depthOffset = 1` and
+     * `$offset = 0`. `$start = ""` instruct the function to start from the
+     * root node (i.e. the node of Pico's main index page at `index.md`).
+     * `$depth` tells the function what pages to return. In this example,
+     * `$depth = 1` matches the start node (i.e. the zeroth generation) and all
+     * its descendant pages until the first generation (i.e. the start node's
+     * children). `$depthOffset` instructs the function to exclude some of the
+     * older generations. `$depthOffset = 1` specifically tells the function
+     * to exclude the zeroth generation, so that the function returns all of
+     * Pico's main index page's direct child pages (like `sub/index.md` and
+     * `page.md`, but not `sub/page.md`) only.
+     *
+     * Passing `$depthOffset = -1` only is the same as passing `$start = ""`,
+     * `$depth = 1`, `$depthOffset = 0` and `$offset = 0`. The only difference
+     * is that `$depthOffset` won't exclude the zeroth generation, so that the
+     * function returns Pico's main index page as well as all of its direct
+     * child pages.
+     *
+     * Passing `$depth = 0`, `$depthOffset = -2` and `$offset = 2` is the same
+     * as passing `$depth = 2`, `$depthOffset = 0` and `$offset = 0`. Both will
+     * return the zeroth, first and second generation of pages. For Pico's main
+     * index page this would be `index.md` (0th gen), `sub/index.md` (1st gen),
+     * `sub/page.md` (2nd gen) and `page.md` (1st gen). If you want to return
+     * 2nd gen pages only, pass `$offset = 2` only (with implicit `$depth = 0`
+     * and `$depthOffset = 0` it's the same as `$depth = 2`, `$depthOffset = 2`
+     * and `$offset = 0`).
+     *
+     * Instead of an integer you can also pass `$depth = null`. This is the
+     * same as passing an infinitely large number as `$depth`, so that this
+     * function simply returns all descendant pages. Consequently passing
+     * `$start = ""`, `$depth = null`, `$depthOffset = 0` and `$offset = 0`
+     * returns Pico's full pages array.
+     *
+     * If `$depth` is negative after taking `$offset` into consideration, the
+     * function will throw a {@see Twig_Error_Runtime} exception, since this
+     * would simply make no sense and is likely an error. Passing a negative
+     * `$depthOffset` is equivalent to passing `$depthOffset = 0`.
+     *
+     * But what about a negative `$offset`? Passing `$offset = -1` instructs
+     * the function not to start from the given `$start` node, but its parent
+     * node. Consequently `$offset = -2` instructs the function to use the
+     * `$start` node's grandparent node. Obviously this won't make any sense
+     * for Pico's root node, but just image `$start = "sub/index"`. Passing
+     * this together with `$offset = -1` is equivalent to `$start = ""` and
+     * `$offset = 0`.
+     *
+     * @param string   $start       name of the node to start from
+     * @param int|null $depth       return pages until the given maximum depth;

-Backward incompatibilities:
-
- * the "items" filter, which has been deprecated for quite a long time now, has been removed
- * the "range" filter has been converted to a function: 0|range(10) -> range(0, 10)
- * the "constant" filter has been converted to a function: {{ some_date|date('DATE_W3C'|constant) }} -> {{ some_date|date(constant('DATE_W3C')) }}
- * the "cycle" filter has been converted to a function: {{ ['odd', 'even']|cycle(i) }} -> {{ cycle(['odd', 'even'], i) }}
- * the "for" tag does not support "joined by" anymore
- * the "autoescape" first argument is now "true"/"false" (instead of "on"/"off")
- * the "parent" tag has been replaced by a "parent" function ({{ parent() }} instead of {% parent %})
- * the "display" tag has been replaced by a "block" function ({{ block('title') }} instead of {% display title %})
- * removed the grammar and simple token parser (moved to the Twig Extensions repository)
-
-Changes:
-
- * added "needs_context" option for filters and functions (the context is then passed as a first argument)
- * added global variables support
- * made macros return their value instead of echoing directly (fixes calling a macro in sandbox mode)
- * added the "from" tag to import macros as functions
- * added support for functions (a function is just syntactic sugar for a getAttribute() call)
- * made macros callable when sandbox mode is enabled
- * added an exception when a macro uses a reserved name
- * the "default" filter now uses the "empty" test instead of just checking for null
- * added the "empty" test
-
-* 0.9.10 (2010-12-16)
-
-Backward incompatibilities:
-
- * The Escaper extension is enabled by default, which means that all displayed
-   variables are now automatically escaped. You can revert to the previous
-   behavior by removing the extension via $env->removeExtension('escaper')
-   or just set the 'autoescape' option to 'false'.
- * removed the "without loop" attribute for the "for" tag (not needed anymore
-   as the Optimizer take care of that for most cases)
- * arrays and hashes have now a different syntax
-     * arrays keep the same syntax with square brackets: [1, 2]
-     * hashes now use curly braces (["a": "b"] should now be written as {"a": "b"})
-     * support for "arrays with keys" and "hashes without keys" is not supported anymore ([1, "foo": "bar"] or {"foo": "bar", 1})
- * the i18n extension is now part of the Twig Extensions repository
-
-Changes:
-
- * added the merge filter
- * removed 'is_escaper' option for filters (a left over from the previous version) -- you must use 'is_safe' now instead
- * fixed usage of operators as method names (like is, in, and not)
- * changed the order of execution for node visitors
- * fixed default() filter behavior when used with strict_variables set to on
- * fixed filesystem loader compatibility with PHAR files
- * enhanced error messages when an unexpected token is parsed in an expression
- * fixed filename not being added to syntax error messages
- * added the autoescape option to enable/disable autoescaping
- * removed the newline after a comment (mimics PHP behavior)
- * added a syntax error exception when parent block is used on a template that does not extend another one
- * made the Escaper extension enabled by default
- * fixed sandbox extension when used with auto output escaping
- * fixed escaper when wrapping a Twig_Node_Print (the original class must be preserved)
- * added an Optimizer extension (enabled by default; optimizes "for" loops and "raw" filters)
- * added priority to node visitors
-
-* 0.9.9 (2010-11-28)
-
-Backward incompatibilities:
- * the self special variable has been renamed to _self
- * the odd and even filters are now tests:
-     {{ foo|odd }} must now be written {{ foo is odd }}
- * the "safe" filter has been renamed to "raw"
- * in Node classes,
-        sub-nodes are now accessed via getNode() (instead of property access)
-        attributes via getAttribute() (instead of array access)
- * the urlencode filter had been renamed to url_encode
- * the include tag now merges the passed variables with the current context by default
-   (the old behavior is still possible by adding the "only" keyword)
- * moved Exceptions to Twig_Error_* (Twig_SyntaxError/Twig_RuntimeError are now Twig_Error_Syntax/Twig_Error_Runtime)
- * removed support for {{ 1 < i < 3 }} (use {{ i > 1 and i < 3 }} instead)
- * the "in" filter has been removed ({{ a|in(b) }} should now be written {{ a in b }})
-
-Changes:
- * added file and line to Twig_Error_Runtime exceptions thrown from Twig_Template
- * changed trans tag to accept any variable for the plural count
- * fixed sandbox mode (__toString() method check was not enforced if called implicitly from complex statements)
- * added the ** (power) operator
- * changed the algorithm used for parsing expressions
- * added the spaceless tag
- * removed trim_blocks option
- * added support for is*() methods for attributes (foo.bar now looks for foo->getBar() or foo->isBar())
- * changed all exceptions to extend Twig_Error
- * fixed unary expressions ({{ not(1 or 0) }})
- * fixed child templates (with an extend tag) that uses one or more imports
- * added support for {{ 1 not in [2, 3] }} (more readable than the current {{ not (1 in [2, 3]) }})
- * escaping has been rewritten
- * the implementation of template inheritance has been rewritten
-   (blocks can now be called individually and still work with inheritance)
- * fixed error handling for if tag when a syntax error occurs within a subparse process
- * added a way to implement custom logic for resolving token parsers given a tag name
- * fixed js escaper to be stricter (now uses a whilelist-based js escaper)
- * added the following filers: "constant", "trans", "replace", "json_encode"
- * added a "constant" test
- * fixed objects with __toString() not being autoescaped
- * fixed subscript expressions when calling __call() (methods now keep the case)
- * added "test" feature (accessible via the "is" operator)
- * removed the debug tag (should be done in an extension)
- * fixed trans tag when no vars are used in plural form
- * fixed race condition when writing template cache
- * added the special _charset variable to reference the current charset
- * added the special _context variable to reference the current context
- * renamed self to _self (to avoid conflict)
- * fixed Twig_Template::getAttribute() for protected properties
-
-* 0.9.8 (2010-06-28)
-
-Backward incompatibilities:
- * the trans tag plural count is now attached to the plural tag:
-    old: `{% trans count %}...{% plural %}...{% endtrans %}`
-    new: `{% trans %}...{% plural count %}...{% endtrans %}`
-
- * added a way to translate strings coming from a variable ({% trans var %})
- * fixed trans tag when used with the Escaper extension
- * fixed default cache umask
- * removed Twig_Template instances from the debug tag output
- * fixed objects with __isset() defined
- * fixed set tag when used with a capture
- * fixed type hinting for Twig_Environment::addFilter() method
-
-* 0.9.7 (2010-06-12)
-
-Backward incompatibilities:
- * changed 'as' to '=' for the set tag ({% set title as "Title" %} must now be {% set title = "Title" %})
- * removed the sandboxed attribute of the include tag (use the new sandbox tag instead)
- * refactored the Node system (if you have custom nodes, you will have to update them to use the new API)
-
- * added self as a special variable that refers to the current template (useful for importing macros from the current template)
- * added Twig_Template instance support to the include tag
- * added support for dynamic and conditional inheritance ({% extends some_var %} and {% extends standalone ? "minimum" : "base" %})
- * added a grammar sub-framework to ease the creation of custom tags
- * fixed the for tag for large arrays (some loop variables are now only available for arrays and objects that implement the Countable interface)
- * removed the Twig_Resource::resolveMissingFilter() method
- * fixed the filter tag which did not apply filtering to included files
- * added a bunch of unit tests
- * added a bunch of phpdoc
- * added a sandbox tag in the sandbox extension
- * changed the date filter to support any date format supported by DateTime
- * added strict_variable setting to throw an exception when an invalid variable is used in a template (disabled by default)
- * added the lexer, parser, and compiler as arguments to the Twig_Environment constructor
- * changed the cache option to only accepts an explicit path to a cache directory or false
- * added a way to add token parsers, filters, and visitors without creating an extension
- * added three interfaces: Twig_NodeInterface, Twig_TokenParserInterface, and Twig_FilterInterface
- * changed the generated code to match the new coding standards
- * fixed sandbox mode (__toString() method check was not enforced if called implicitly from a simple statement like {{ article }})
- * added an exception when a child template has a non-empty body (as it is always ignored when rendering)
-
-* 0.9.6 (2010-05-12)
-
- * fixed variables defined outside a loop and for which the value changes in a for loop
- * fixed the test suite for PHP 5.2 and older versions of PHPUnit
- * added support for __call() in expression resolution
- * fixed node visiting for macros (macros are now visited by visitors as any other node)
- * fixed nested block definitions with a parent call (rarely useful but nonetheless supported now)
- * added the cycle filter
- * fixed the Lexer when mbstring.func_overload is used with an mbstring.internal_encoding different from ASCII
- * added a long-syntax for the set tag ({% set foo %}...{% endset %})
- * unit tests are now powered by PHPUnit

- * fixed twig_capitalize_string_filter() and fixed twig_length_filter() when used with UTF-8 values
- * added a more useful exception if an if tag is not closed properly
- * added support for escaping strategy in the autoescape tag
- * fixed lexer when a template has a big chunk of text between/in a block
-
-* 0.9.5 (2010-01-20)
-
-As for any new release, don't forget to remove all cached templates after
-upgrading.
-
-If you have defined custom filters, you MUST upgrade them for this release. To
-upgrade, replace "array" with "new Twig_Filter_Function", and replace the
-environment constant by the "needs_environment" option:
-
-  // before
-  'even'   => array('twig_is_even_filter', false),
-  'escape' => array('twig_escape_filter', true),
-
-  // after
-  'even'   => new Twig_Filter_Function('twig_is_even_filter'),
-  'escape' => new Twig_Filter_Function('twig_escape_filter', array('needs_environment' => true)),
-
-If you have created NodeTransformer classes, you will need to upgrade them to
-the new interface (please note that the interface is not yet considered
-stable).
-
- * fixed list nodes that did not extend the Twig_NodeListInterface
- * added the "without loop" option to the for tag (it disables the generation of the loop variable)
- * refactored node transformers to node visitors
- * fixed automatic-escaping for blocks
- * added a way to specify variables to pass to an included template
- * changed the automatic-escaping rules to be more sensible and more configurable in custom filters (the documentation lists all the rules)
- * improved the filter system to allow object methods to be used as filters
- * changed the Array and String loaders to actually make use of the cache mechanism
- * included the default filter function definitions in the extension class files directly (Core, Escaper)
- * added the // operator (like the floor() PHP function)
- * added the .. operator (as a syntactic sugar for the range filter when the step is 1)
- * added the in operator (as a syntactic sugar for the in filter)
- * added the following filters in the Core extension: in, range
- * added support for arrays (same behavior as in PHP, a mix between lists and dictionaries, arrays and hashes)
- * enhanced some error messages to provide better feedback in case of parsing errors
-
-* 0.9.4 (2009-12-02)
-
-If you have custom loaders, you MUST upgrade them for this release: The
-Twig_Loader base class has been removed, and the Twig_LoaderInterface has also
-been changed (see the source code for more information or the documentation).
-
- * added support for DateTime instances for the date filter
- * fixed loop.last when the array only has one item
- * made it possible to insert newlines in tag and variable blocks
- * fixed a bug when a literal '\n' were present in a template text
- * fixed bug when the filename of a template contains */
- * refactored loaders
-
-* 0.9.3 (2009-11-11)
-
-This release is NOT backward compatible with the previous releases.
-
-  The loaders do not take the cache and autoReload arguments anymore. Instead,
-  the Twig_Environment class has two new options: cache and auto_reload.
-  Upgrading your code means changing this kind of code:
-
-      $loader = new Twig_Loader_Filesystem('/path/to/templates', '/path/to/compilation_cache', true);
-      $twig = new Twig_Environment($loader);
-
-  to something like this:
-
-      $loader = new Twig_Loader_Filesystem('/path/to/templates');
-      $twig = new Twig_Environment($loader, array(
-        'cache' => '/path/to/compilation_cache',
-        'auto_reload' => true,
-      ));
-
- * deprecated the "items" filter as it is not needed anymore
- * made cache and auto_reload options of Twig_Environment instead of arguments of Twig_Loader
- * optimized template loading speed
- * removed output when an error occurs in a template and render() is used
- * made major speed improvements for loops (up to 300% on even the smallest loops)
- * added properties as part of the sandbox mode
- * added public properties support (obj.item can now be the item property on the obj object)
- * extended set tag to support expression as value ({% set foo as 'foo' ~ 'bar' %} )
- * fixed bug when \ was used in HTML
-
-* 0.9.2 (2009-10-29)
-
- * made some speed optimizations
- * changed the cache extension to .php
- * added a js escaping strategy
- * added support for short block tag
- * changed the filter tag to allow chained filters
- * made lexer more flexible as you can now change the default delimiters

- * made Twig_Autoloader::autoload() a static method
- * avoid writing template file if an error occurs
- * added $ escaping when outputting raw strings

- * fixed empty cache files when the template contains an error
-
-* 0.9.1 (2009-10-14)
-
-  * fixed a bug in PHP 5.2.6
-  * fixed numbers with one than one decimal
-  * added support for method calls with arguments ({{ foo.bar('a', 43) }})

-
-* 0.9.0 (2009-10-12)
-
- * Initial release

-==============================================================
-
-[![Build Status](https://secure.travis-ci.org/fabpot/Twig.png?branch=master)](http://travis-ci.org/fabpot/Twig)
-
-Twig is a template language for PHP, released under the new BSD license (code
-and documentation).
-
-Twig uses a syntax similar to the Django and Jinja template languages which
-inspired the Twig runtime environment.
