-CKEditor 4 Changelog
-====================
+⚠️️️ **CKEditor 4 (the open source edition) is no longer maintained.** ⚠️
+
+If you would like to keep access to future CKEditor 4 security patches, check the [Extended Support Model](https://ckeditor.com/ckeditor-4-support/), which guarantees **security updates and critical bug fixes until December 2026**. Alternatively, [upgrade to CKEditor 5](https://ckeditor.com/docs/ckeditor5/latest/updating/ckeditor4/migration-from-ckeditor-4.html).
+
+## CKEditor 4.22.0 / 4.22.1
+
+⚠️ This is the last open source release of CKEditor 4. As announced in 2018, CKEditor 4 has reached its End of Life in June 2023.
+
+
+New Features:
+
+* [#5316](https://github.com/ckeditor/ckeditor4/issues/5316): Added vertical margins support for list elements in the [Paste from Word](https://ckeditor.com/cke4/addon/pastefromword) plugin.
+* [#5410](https://github.com/ckeditor/ckeditor4/issues/5410): Added the ability to indicate the language of styles in the [Styles Combo](https://ckeditor.com/cke4/addon/stylescombo) plugin via the [`config.styleSet`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-stylesSet) configuration option.
+* [#5510](https://github.com/ckeditor/ckeditor4/issues/5510): Added notification system to the editor informing users that the editor version is up-to-date and secure. See [`config.versionCheck`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-versionCheck) configuration option to learn more.
+
+Fixed Issues:
+
+* [#5437](https://github.com/ckeditor/ckeditor4/issues/5437): Fixed: Incorrect indication of selected items in combo boxes. The selected item was unmarked upon each opening of the combo box.
+* [#5495](https://github.com/ckeditor/ckeditor4/issues/5495): Fixed: Insufficient color ratio for links inside [Notifications](https://ckeditor.com/cke4/addon/notification).
+
+Other Changes:
+
+* [#5412](https://github.com/ckeditor/ckeditor4/issues/5412): Prevent using `document.domain` in Firefox in the [Preview](https://ckeditor.com/cke4/addon/preview) plugin.
+
+Note: CKEditor 4.22.1 has been released immediately after 4.22.0 to fix the README issues on [npm](https://www.npmjs.com/) and contains no changes vs 4.22.0.
+
+## CKEditor 4.21.0
+
+**Security Updates:**
+
+A cross-site scripting vulnerability has been discovered affecting [Iframe Dialog](https://ckeditor.com/cke4/addon/iframe) and [Media Embed](https://ckeditor.com/cke4/addon/embed) plugins.
+
+This vulnerability might affect a small percentage of integrators that depend on dynamic editor initialization/destroy mechanism. See [GitHub advisory](https://github.com/ckeditor/ckeditor4/security/advisories/GHSA-vh5c-xwqv-cv9g) for more details.
+
+**Potential breaking changes**
+
+In some rare cases, a security release may introduce a breaking change to your application. We have provided configuration options that will help you mitigate any potential issues with the upgrade:
+
+- Starting from version 4.21, the [Iframe Dialog](https://ckeditor.com/cke4/addon/iframe) plugin applies the `sandbox` attribute by default, which restricts JavaScript code execution in the iframe element. To change this behavior, configure the [`config.iframe_attributes`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-iframe_attributes) option.
+- Starting from version 4.21, the [Media Embed](https://ckeditor.com/cke4/addon/embed) plugin regenerates the entire content of the embed widget by default. To change this behavior, configure the [`config.embed_keepOriginalContent`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-embed_keepOriginalContent) option.
+
+If you choose to change either of the above options, make sure to properly configure [Content Security Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP) to avoid any potential security issues that may arise from embedding iframe elements on your web page.
+
+You can read more details in the relevant security advisory and [contact us](security@cksource.com) if you have more questions.
+
+**An upgrade is highly recommended!**

+* [#5352](https://github.com/ckeditor/ckeditor4/issues/5352): Added the [`colorButton_contentsCss`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-colorButton_contentsCss) configuration option allowing to add custom CSS to the [Color Button](https://ckeditor.com/cke4/addon/colorbutton) menu content.

+* [#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)!

+
+## CKEditor 4.19.1
+
+Fixed Issues:
+
+* [#5125](https://github.com/ckeditor/ckeditor4/issues/5125): Fixed: Deleting a widget with disabled [autoParagraph](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-autoParagraph) by the keyboard `backspace` key removes the editor editable area and crashes the editor.

Trying to paste unsupported files will result in a notification that a file cannot be dropped or pasted into the editor.
+* [#2445](https://github.com/ckeditor/ckeditor4/issues/2445): Added [`config.applicationTitle`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-applicationTitle) alongside [`CKEDITOR.editor#applicationTitle`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#property-applicationTitle) to allow customizing editor's application region label.
+
+## CKEditor 4.18.0
+
+**Security Updates:**
+
+* Fixed an XSS vulnerability in the core module reported by GitHub Security Lab team member [Kevin Backhouse](https://github.com/kevinbackhouse).

+## CKEditor 4.17.1
+
+**Highlights:**
+
+Due to a regression in CKEeditor 4.17.0 version that was only revealed after the release and affected a limited area of operation, CSS assets loaded via relative links started to point into invalid location when loaded from external resources.
+
+We have therefore decided to immediately release CKEditor 4.17.1 that fixed this problem. If you have already upgraded to v4.17.0, make sure to upgrade to v4.17.1 to avoid this regression.
+
+Fixed issues:
+
+* [#4979](https://github.com/ckeditor/ckeditor4/issues/3757): Fixed: Added cache key in [#4761](https://github.com/ckeditor/ckeditor4/issues/4761) started to breaking relative links for external CSS resources. The fix has been reverted and will be corrected in the next editor version.
