 ====================
 
+## CKEditor 4.20.1
+
+Fixed Issues:
+
+* [#5333](https://github.com/ckeditor/ckeditor4/issues/5333): Fixed: The original name of the uploaded image is not preserved by the [Upload Image](https://ckeditor.com/cke4/addon/uploadimage) plugin if the [Clipboard](https://ckeditor.com/cke4/addon/clipboard) plugin has enabled image handling.
+* [#2881](https://github.com/ckeditor/ckeditor4/issues/2881): Fixed: Changing table headers from "Both" to "First column" in the [Table](https://ckeditor.com/cke4/addon/table) dialog does not change the first column cell correctly.
+* [#2996](https://github.com/ckeditor/ckeditor4/issues/2996): Fixed: Table header "scope" attribute is incorrect for the "Headers: both" option in the [Table](https://ckeditor.com/cke4/addon/table) dialog.
+* [#4802](https://github.com/ckeditor/ckeditor4/issues/4802): Fixed: [Tableselection](https://ckeditor.com/cke4/addon/tableselection) caret moves to the previous cell after tabbing into the next cell and then removing its content.
+* [#5365](https://github.com/ckeditor/ckeditor4/issues/5365): Fixed: The value of the [`config.baseFloatZIndex`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-baseFloatZIndex) config variable is incorrectly applied to parent dialog when the child dialog is closed resulting in the dialog overlay covering up the dialog. Thanks to [JenoDK](https://github.com/JenoDK)!
+* [#5305](https://github.com/ckeditor/ckeditor4/issues/5305): Fixed: Anchor name can invalidly include spaces.
