As mentioned in https://www.php.net/manual/en/function.basename.php both
basename() and dirname() are locale aware.
An incorrect locale can cause the page tree to behave in strange ways.
For example the structure
/über-uns
|-index.md
|-impressum.md
could lead to the page impressum not being a child of über-uns.

* [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
```
A few days ago Parsedown released new ("stable") versions of Parsedown and Parsedown Extra: Parsedown 1.7.4 and Parsedown Extra 0.8.1. Parsedown 1.7.4 backports some features of Parsedown 1.8.0-beta-7 and is compatible with Parsedown Extra 0.8.1. However, due to these changes Parsedown Extra 0.8.1 now breaks compatibility with Parsedown 1.8.0-beta-7. Parsedown's release process is messed up beyond repair... Not sure what we're going to do now, this needs some research whether we can downgrade to Parsedown 1.7.4 without breaking things (what would require us to release a new major release, i.e. Pico 3.0). For now we're pinning Parsedown 1.8.0-beta-7 and Parsedown Extra 0.8.0-beta-1 as of Pico 2.1.0.
This is **Pico 2.1 - small, but mighty!**
If you want to upgrade to Pico 2.1, simply follow the usual upgrade instructions for minor releases. Installing Pico is as easy as before. You can find more extensive upgrade instructions as well as a complete list of all additions and changes in Pico's [upgrade docs](http://picocms.org/in-depth/upgrade-pico-21/) - even though this is a minor release, it's still a lot of new and improved stuff!
You might also want to give [Pico CMS for Nextcloud `v1.0.0`](https://apps.nextcloud.com/apps/cms_pico) a try - it's now an official part of Pico. You can find more info at [picocms.org](http://picocms.org/plugins/#pico-cms-for-nextcloud)
```
* [Changed] Add Pico's official logo and tagline to `content-sample/_meta.md`
* [Changed] Improve `content-sample/theme.md` to show Pico's official logo and
the usage of the new image utility classes of Pico's default theme
* [Changed] Improve Pico docs and PHPDoc class docs
```
Unfortunately we must force Composer minimum stability <= beta due to Parsedown 1.8 currently being in beta. Composer AFAIK can't decide this on a per-dependency basis...
Pico doesn't require 'ext-dom' itself, Parsedown Extra does; Parsedown Extra didn't declare this dependency before, but Parsedown Extra 0.8 finally does.
```
* [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,
cehcking 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] Introduce API version 3
* [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 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 `$endSlash` params to `Pico::getAbsolutePath()`
* [Changed] Deprecate `Pico::getBaseThemeUrl()`
* [Changed] Replace various `file_exists` calls with proper `is_file` calls
* [Changed] Refactor release & build system
* [Changed] Improve PHP class docs
* [Changed] Various small improvements
* [Removed] Remove superfluous `base_dir` and `theme_dir` Twig variables
* [Removed] Remove `PicoPluginInterface::__construct()`
```
- Separate Travis branch deployment and release deployment stages (also makes `deploy.sh` obsolete)
- Add `clean.sh` and `release.sh` scripts to allow users to create "release" packages locally
- Use `setup/*.sh` scripts to check and install build dependencies (like PHP_CodeSniffer, phpDocumentor and cloc)
- Use `create-release.sh` of `picocms/ci-tools` to create release archives
- Streamline script usage
Use the following to test Pico and to create a "release" package locally:
```sh
cd ~/My-Pico-Workspace/Components/pico
ln -rs ../ci-tools .build/ci-tools
. ./.build/ci-tools/init/local.sh.inc
. ./.build/init.sh.inc
phpcs --standard=.phpcs.xml "$PICO_PROJECT_DIR"
clean.sh
release.sh
```
