 ====================
 
+## 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.
+* [#5135](https://github.com/ckeditor/ckeditor4/issues/5135): Fixed: The [`checkbox.setValue`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_ui_dialog_checkbox.html#method-setValue) and [`radio.setValue`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_ui_dialog_radio.html#method-setValue) methods are not chainable as stated in the documentation. Thanks to [Jordan Bradford](https://github.com/LordPachelbel)!
+* [#5085](https://github.com/ckeditor/ckeditor4/issues/5085): Fixed: The [Language](https://ckeditor.com/cke4/addon/language) plugin removes the element marking the text in foreign language if said element does not have an information about the text direction.
+* [#4284](https://github.com/ckeditor/ckeditor4/issues/4284): Fixed: [Tableselection](https://ckeditor.com/cke4/addon/tableselection) Merging cells with a rowspan throws an unexpected error and does not create an undo step.
+* [#5184](https://github.com/ckeditor/ckeditor4/issues/5184): Fixed: The [Editor Placeholder](https://ckeditor.com/cke4/addon/wysiwygarea) plugin degrades typing performance.
+* [#5158](https://github.com/ckeditor/ckeditor4/issues/5158): Fixed: [`CKEDITOR.tools#convertToPx()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_tools.html#method-convertToPx) gives invalid results if the helper calculator element was deleted from the DOM.
+* [#5234](https://github.com/ckeditor/ckeditor4/issues/5234): Fixed: [Easy Image](https://ckeditor.com/cke4/addon/easyimage) doesn't allow to upload images files using toolbar button.

+* [#4449](https://github.com/ckeditor/ckeditor4/issues/4449): Fixed: [`dialog.validate#functions`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dialog_validate.html#method-functions) incorrectly composes functions that return an optional error message, like e.g. [`dialog.validate.number`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dialog_validate.html#method-number) due to unnecessary return type coercion.
+* [#4473](https://github.com/ckeditor/ckeditor4/issues/4473): Fixed: The [dialog.validate](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dialog_validate.html) method does not accept parameter value. The issue originated in [dialog.validate.functions](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dialog_validate.html#method-functions) method that did not properly propagate parameter value to validator. Affected validators:
+	* [`functions`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dialog_validate.html#method-functions)
+	* [`equals`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dialog_validate.html#method-equals)

+	* [`htmlLength`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dialog_validate.html#method-htmlLength)
+	* [`inlineStyle`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dialog_validate.html#method-inlineStyle)
+* [#5147](https://github.com/ckeditor/ckeditor4/issues/5147): Fixed: The [Accessibility Help](https://ckeditor.com/cke4/addon/a11yhelp) dialog does not contain info about focus being moved back to the editing area upon leaving dialogs.

+* [#5022](https://github.com/ckeditor/ckeditor4/issues/5022): Fixed: [Find and Replace](https://ckeditor.com/cke4/addon/find) does not respond to the `Enter` key.
+
+API changes:
+
+* [#5184](https://github.com/ckeditor/ckeditor4/issues/5184): Added the [`config.editorplaceholder_delay`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-editorplaceholder_delay) configuration option allowing to delay placeholder before it is toggled when changing editor content.
+* [#5184](https://github.com/ckeditor/ckeditor4/issues/5184): Added the [`CKEDITOR.tools#debounce()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_tools.html#method-debounce) function allowing to postpone a passed function execution until the given milliseconds have elapsed since the last time it was invoked.
+
+## CKEditor 4.19.0
+
+New features:
+
+* [#2444](https://github.com/ckeditor/ckeditor4/issues/2444): Togglable toolbar buttons are now exposed as toggle buttons in the browser's accessibility tree.
+* [#4641](https://github.com/ckeditor/ckeditor4/issues/4641): Added an option allowing to cancel the [Delayed Editor Creation](https://ckeditor.com/docs/ckeditor4/latest/features/delayed_creation.html) feature as a function handle for editor creators ([`CKEDITOR.replace`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.html#method-replace), [`CKEDITOR.inline`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.html#method-inline), [`CKEDITOR.appendTo`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.html#method-appendTo)).
+* [#4986](https://github.com/ckeditor/ckeditor4/issues/4986): Added [`config.shiftLineBreaks`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-shiftLineBreaks) allowing to preserve inline elements formatting when the `shift`+`enter` keystroke is used.
+* [#2445](https://github.com/ckeditor/ckeditor4/issues/2445): Added [`config.applicationTitle`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-applicationTitle) configuration option allowing to customize or disable the editor's application region label. This option, combined with [`config.title`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-title), gives much better control over the editor's labels read by screen readers.
+
+Fixed Issues:
+
+* [#4543](https://github.com/ckeditor/ckeditor4/issues/4543): Fixed: Toolbar buttons toggle state is not correctly announced by screen readers lacking the information whether the feature is on or off.
+* [#4052](https://github.com/ckeditor/ckeditor4/issues/4052): Fixed: Editor labels are read incorrectly by screen readers due to invalid editor control type for the [Iframe Editing Area](https://ckeditor.com/cke4/addon/wysiwygarea) editors.

+* [#3394](https://github.com/ckeditor/ckeditor4/issues/3394): Fixed: [Enhanced image](https://ckeditor.com/cke4/addon/image2) plugin dialog is not supporting URL with query string parameters. Thanks to [Simon Urli](https://github.com/surli)!
+* [#5049](https://github.com/ckeditor/ckeditor4/issues/5049): Fixed: The editor fails in strict mode due to not following the `use strict` directives in a core editor module.
+* [#5095](https://github.com/ckeditor/ckeditor4/issues/5095): Fixed: The [clipboard](https://ckeditor.com/cke4/addon/clipboard) plugin shows notification about unsupported file format when the file type is different than `jpg`, `gif`, `png`, not respecting [supported types](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_fileTools_uploadWidgetDefinition.html#property-supportedTypes) by the [Upload Widget](https://ckeditor.com/cke4/addon/uploadwidget) plugin.
+* [#4855](https://github.com/ckeditor/ckeditor4/issues/4855): [iOS] Fixed: Focusing toolbar buttons with an enabled VoiceOver screen reader moves the browser focus into an editable area and interrupts button functionality.
+
+API changes:
+
+* [#4641](https://github.com/ckeditor/ckeditor4/issues/4641): The [`CKEDITOR.replace`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.html#method-replace), [`CKEDITOR.inline`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.html#method-inline), [`CKEDITOR.appendTo`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.html#method-appendTo) functions are now returning a handle function allowing to cancel the [Delayed Editor Creation](https://ckeditor.com/docs/ckeditor4/latest/features/delayed_creation.html) feature.
+* [#5095](https://github.com/ckeditor/ckeditor4/issues/5095): Added the [CKEDITOR.plugins.clipboard.addFileMatcher](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_clipboard.html#method-addFileMatcher) function allowing to define file formats supported by the [clipboard](https://ckeditor.com/cke4/addon/clipboard) plugin. 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).
+
+	Issue summary: The vulnerability allowed to inject malformed HTML bypassing content sanitization, which could result in executing a JavaScript code. See [CVE-2022-24728](https://github.com/ckeditor/ckeditor4/security/advisories/GHSA-4fc4-4p5g-6w89) for more details.
+
+* Fixed a Regular expression Denial of Service (ReDoS) vulnerability in dialog plugin discovered by the CKEditor 4 team during our regular security audit.
+
+	Issue summary: The vulnerability allowed to abuse a dialog input validator regular expression, which could cause a significant performance drop resulting in a browser tab freeze. See [CVE-2022-24729](https://github.com/ckeditor/ckeditor4/security/advisories/GHSA-f6rf-9m92-x2hh) for more details.

+
+**An upgrade is highly recommended!**
+
+**Highlights:**
+
+[Web Spell Checker](https://webspellchecker.com/) ended support for WebSpellChecker Dialog on December 31st, 2021. This means the plugin is not supported any longer. Therefore, we decided to deprecate and remove the WebSpellChecker Dialog plugin from CKEditor 4 presets.
+
+We strongly encourage everyone to choose one of the other available spellchecking solutions - [Spell Check As You Type (SCAYT)](https://ckeditor.com/cke4/addon/scayt) or [WProofreader](https://ckeditor.com/cke4/addon/wproofreader).
+
+Fixed issues:
+
+* [#5097](https://github.com/ckeditor/ckeditor4/issues/5097): [Chrome] Fixed: Incorrect conversion of points to pixels while using [`CKEDITOR.tools.convertToPx()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_tools.html#method-convertToPx).

+* [#5127](https://github.com/ckeditor/ckeditor4/issues/5127): Deprecated the [`CKEDITOR.rnd`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.html#property-rnd) property to discourage using it in a security-sensitive context.
+* [#5087](https://github.com/ckeditor/ckeditor4/issues/5087): Improved the jQuery adapter by replacing a deprecated jQuery API with existing counterparts. Thanks to [Fran Boon](https://github.com/flavour)!
+* [#5128](https://github.com/ckeditor/ckeditor4/issues/5128): Improved the [Emoji](https://ckeditor.com/cke4/addon/emoji) definitions encoding set by the [`config.emoji_emojiListUrl`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-emoji_emojiListUrl) configuration option.

+* [#4873](https://github.com/ckeditor/ckeditor4/issues/4873): Fixed: Pasting content from MS Word and Outlook with horizontal lines prevents images from being uploaded.
+* [#4952](https://github.com/ckeditor/ckeditor4/issues/4952): Fixed: Dragging and dropping images within a table cell appends additional elements.
+* [#4761](https://github.com/ckeditor/ckeditor4/issues/4761): Fixed: Some CSS files are missing unique timestamp used to prevent browser to cache static resources between editor releases.
+* [#4987](https://github.com/ckeditor/ckeditor4/issues/4987): Fixed: [Find/Replace](https://ckeditor.com/cke4/addon/find) is not recognizing more than one space character.
+* [#5061](https://github.com/ckeditor/ckeditor4/issues/5061): Fixed: [Find/Replace](https://ckeditor.com/cke4/addon/find) plugin incorrectly handles multiple whitespace during replacing text.
+* [#5004](https://github.com/ckeditor/ckeditor4/issues/5004): Fixed: `MutationObserver` used in [IFrame Editing Area](https://ckeditor.com/cke4/addon/wysiwygarea) plugin causes memory leaks.
+* [#4994](https://github.com/ckeditor/ckeditor4/issues/4994): Fixed: [Easy Image](https://ckeditor.com/cke4/addon/easyimage) plugin caused content pasted from Word to turn into an image.

+* [#4761](https://github.com/ckeditor/ckeditor4/issues/4761): The [`CKEDITOR.appendTimestamp()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.html#method-appendTimestamp) function was added.

+
+Other changes:
+
+* [#5014](https://github.com/ckeditor/ckeditor4/issues/5014): Fixed: Toolbar configurator fails when plugin does not define a toolbar group. Thanks to [SuperPat](https://github.com/SuperPat45)!
+
+## 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.
+
+## CKEditor 4.17

+
+**An upgrade is highly recommended!**
+
+**Highlights:**
+
+Adobe [ended support of Flash Player](https://www.adobe.com/products/flashplayer/end-of-life.html) on December 31, 2020 and blocked Flash content from running in Flash Player beginning January 12, 2021.
+We have decided to deprecate and remove the [Flash](https://ckeditor.com/cke4/addon/flash) plugin from CKEditor 4 to help protect users' systems and discourage using insecure software.

+
+* [#3433](https://github.com/ckeditor/ckeditor4/issues/3433): Marked required fields in dialogs with asterisk (`*`) symbol.

+CKEditor 4 - Releases
-==========
+=====================
 
-Copyright (c) 2003-2019, CKSource - Frederico Knabben. All rights reserved.
+## Releases Code
-https://ckeditor.com - See LICENSE.md for license information.
 
-CKEditor 4 is a text editor to be used inside web pages. It's not a replacement
+This repository contains the official release versions of [CKEditor 4](https://ckeditor.com/ckeditor-4/).
-for desktop text editors like Word or OpenOffice, but a component to be used as
+
-part of web applications and websites.
+There are four versions for each release — `standard-all`, `basic`, `standard`, and `full`.
+They differ in the number of plugins that are compiled into the main `ckeditor.js` file as well as the toolbar configuration.
+
+See the [comparison](https://ckeditor.com/cke4/presets) of the `basic`, `standard`, and `full` installation presets for more details.
+
+The `standard-all` build includes all official CKSource plugins with only those from the `standard` installation preset compiled into the `ckeditor.js` file and enabled in the configuration.
+
+All versions available in this repository were built using [CKBuilder](https://ckeditor.com/cke4/builder), so they are optimized and ready to be used in a production environment.
 
 ## Documentation
 
-The full editor documentation is available online at the following address:
+Developer documentation for CKEditor is available online at: <https://ckeditor.com/docs/>.
-https://ckeditor.com/docs/
 
 ## Installation
 
-Installing CKEditor is an easy task. Just follow these simple steps:
+### Git clone
 
- 1. **Download** the latest version from the CKEditor website:
+To install one of the available releases, just clone this repository and switch to the respective branch (see next section):
-    https://ckeditor.com. You should have already completed this step, but be
-    sure you have the very latest version.
- 2. **Extract** (decompress) the downloaded file into the root of your website.
 
-**Note:** CKEditor is by default installed in the `ckeditor` folder. You can
+	git clone -b <release branch> git://github.com/ckeditor/ckeditor4-releases.git
-place the files in whichever you want though.
+
+### Git submodule
+
+If you are using git for your project and you want to integrate CKEditor, we recommend to add this repository as a
+[submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules).
+
+	git submodule add -b <release branch> git://github.com/ckeditor/ckeditor-releases.git <clone dir>
+	git commit -m "Added CKEditor submodule in <clone dir> directory."
+
+### Using Package Managers
+
+See the [Installing CKEditor with Package Managers](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_package_managers.html) article for more details about installing CKEditor with [Bower](https://bower.io), [Composer](https://getcomposer.org/) and [npm](https://www.npmjs.com/).
+
+## Repository Structure
+
+### Branches
+
+This repository contains the following branches:
+
+  - `master` and `latest` &ndash; the latest release of the `standard-all` preset (including betas).
+  - `stable` &ndash; the latest stable release of the `standard-all` preset (non-beta).
+  - `A.B.x` (e.g. `4.3.x`) &ndash; the latest release of the `standard-all` preset in the `A.B` branch.
+  - `(basic|standard|full)/stable` &ndash; the latest stable release tag point (non-beta).
+  - `(basic|standard|full)/latest` &ndash; the latest release tag point (including betas).
+  - `(basic|standard|full)/A.B.x` (e.g. `basic/4.0.x`) &ndash; the latest releases in the `A.B` branch.
+
+### Tags
+
+**Since version 4.3.3** this repository uses the following tag naming rules:
+
+  - `x.y.z` &ndash; contains the `standard-all` editor build, e.g. `4.3.3`, `4.4.0` etc.
+  - `(basic|standard|full)/x.y.z` &ndash; contains the editor build with a given preset, e.g. `basic/4.3.3`.
+
+The version numbers follow the [Semantic Versioning 2.0.0](http://semver.org/) scheme.
+
+Up to version **4.3.2** the tags were released in the following form `x.y[.z]/(basic|standard|full)`.
+For example: `4.0/basic`, `4.0.1/standard`. This convention was changed in CKEditor 4.3.3 to conform to the Semantic Versioning scheme.
