+* [#11809](http://dev.ckeditor.com/ticket/11809): Changed tab size in `

+
+## CKEditor 4.4
+
+**Important Notes:**
+
+* Marked the [`editor.beforePaste`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-beforePaste) event as deprecated.
+* The default class of captioned images has changed to `image` (was: `caption`). Please note that once edited in CKEditor 4.4+, all existing images of the `caption` class (`
`) will be [filtered out](http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter) unless the [`config.image2_captionedClass`](http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-image2_captionedClass) option is set to `caption`. For backward compatibility (i.e. when upgrading), it is highly recommended to use this setting, which also helps prevent CSS conflicts, etc. This does not apply to new CKEditor integrations.
+* Widgets without defined buttons are no longer registered automatically to the [Advanced Content Filter](http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter). Before CKEditor 4.4 widgets were registered to the ACF which was an incorrect behavior ([#11567](http://dev.ckeditor.com/ticket/11567)). This change should not have any impact on standard scenarios, but if your button does not execute the widget command, you need to set [`allowedContent`](http://docs.ckeditor.com/#!/api/CKEDITOR.feature-property-allowedContent) and [`requiredContent`](http://docs.ckeditor.com/#!/api/CKEDITOR.feature-property-requiredContent) properties for it manually, because the editor will not be able to find them.
+* The [Show Borders](http://ckeditor.com/addon/showborders) plugin was added to the Standard installation package in order to ensure that unstyled tables are still visible for the user ([#11665](http://dev.ckeditor.com/ticket/11665)).
+* Since CKEditor 4.4 the editor instance should be passed to [`CKEDITOR.style`](http://docs.ckeditor.com/#!/api/CKEDITOR.style) methods to ensure full compatibility with other features (e.g. applying styles to widgets requires that). We ensured backward compatibility though, so the [`CKEDITOR.style`](http://docs.ckeditor.com/#!/api/CKEDITOR.style) will work even when the editor instance is not provided.
+
+New Features:
+
+* [#11297](http://dev.ckeditor.com/ticket/11297): Styles can now be applied to widgets. The definition of a style which can be applied to a specific widget must contain two additional properties — `type` and `widget`. Read more in the [Widget Styles](http://docs.ckeditor.com/#!/guide/dev_styles-section-widget-styles) section of the "Syles Drop-down" guide. Note that by default, widgets support only classes and no other attributes or styles. Related changes and features:
+ * Introduced the [`CKEDITOR.style.addCustomHandler()`](http://docs.ckeditor.com/#!/api/CKEDITOR.style-static-method-addCustomHandler) method for registering custom style handlers.
+ * The [`CKEDITOR.style.apply()`](http://docs.ckeditor.com/#!/api/CKEDITOR.style-method-apply) and [`CKEDITOR.style.remove()`](http://docs.ckeditor.com/#!/api/CKEDITOR.style-method-remove) methods are now called with an editor instance instead of the document so they can be reused by the [`CKEDITOR.editor.applyStyle()`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-method-applyStyle) and [`CKEDITOR.editor.removeStyle()`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-method-removeStyle) methods. Backward compatibility was preserved, but from CKEditor 4.4 it is highly recommended to pass an editor instead of a document to these methods.
+ * Many new methods and properties were introduced in the [Widget API](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.widget) to make the handling of styles by widgets fully customizable. See: [`widget.definition.styleableElements`](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.widget.definition-property-styleableElements), [`widget.definition.styleToAllowedContentRule`](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.widget.definition-property-styleToAllowedContentRules), [`widget.addClass()`](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.widget-method-addClass), [`widget.removeClass()`](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.widget-method-removeClass), [`widget.getClasses()`](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.widget-method-getClasses), [`widget.hasClass()`](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.widget-method-hasClass), [`widget.applyStyle()`](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.widget-method-applyStyle), [`widget.removeStyle()`](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.widget-method-removeStyle), [`widget.checkStyleActive()`](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.widget-method-checkStyleActive).
+ * Integration with the [Allowed Content Filter](http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter) required an introduction of the [`CKEDITOR.style.toAllowedContent()`](http://docs.ckeditor.com/#!/api/CKEDITOR.style-method-toAllowedContentRules) method which can be implemented by the custom style handler and if exists, it is used by the [`CKEDITOR.filter`](http://docs.ckeditor.com/#!/api/CKEDITOR.filter) to translate a style to [allowed content rules](http://docs.ckeditor.com/#!/api/CKEDITOR.filter.allowedContentRules).
+* [#11300](http://dev.ckeditor.com/ticket/11300): Various changes in the [Enhanced Image](http://ckeditor.com/addon/image2) plugin:
+ * Introduced the [`config.image2_captionedClass`](http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-image2_captionedClass) option to configure the class of captioned images.
+ * Introduced the [`config.image2_alignClasses`](http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-image2_alignClasses) option to configure the way images are aligned with CSS classes.
+ If this setting is defined, the editor produces classes instead of inline styles for aligned images.
+ * Default image caption can be translated (customized) with the `editor.lang.image2.captionPlaceholder` string.
+* [#11341](http://dev.ckeditor.com/ticket/11341): [Enhanced Image](http://ckeditor.com/addon/image2) plugin: It is now possible to add a link to any image type.
+* [#10202](http://dev.ckeditor.com/ticket/10202): Introduced wildcard support in the [Allowed Content Rules](http://docs.ckeditor.com/#!/guide/dev_allowed_content_rules) format.
+* [#10276](http://dev.ckeditor.com/ticket/10276): Introduced blacklisting in the [Allowed Content Filter](http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter).
+* [#10480](http://dev.ckeditor.com/ticket/10480): Introduced code snippets with code highlighting. There are two versions available so far — the default [Code Snippet](http://ckeditor.com/addon/codesnippet) which uses the [highlight.js](http://highlightjs.org) library and the [Code Snippet GeSHi](http://ckeditor.com/addon/codesnippetgeshi) which uses the [GeSHi](http://qbnz.com/highlighter/) library.
+* [#11737](http://dev.ckeditor.com/ticket/11737): Introduced an option to prevent [filtering](http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter) of an element that matches custom criteria (see [`filter.addElementCallback()`](http://docs.ckeditor.com/#!/api/CKEDITOR.filter-method-addElementCallback)).
+* [#11532](http://dev.ckeditor.com/ticket/11532): Introduced the [`editor.addContentsCss()`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-method-addContentsCss) method that can be used for [adding custom CSS files](http://docs.ckeditor.com/#!/guide/plugin_sdk_styles).
+* [#11536](http://dev.ckeditor.com/ticket/11536): Added the [`CKEDITOR.tools.htmlDecode()`](http://docs.ckeditor.com/#!/api/CKEDITOR.tools-method-htmlDecode) method for decoding HTML entities.
+* [#11225](http://dev.ckeditor.com/ticket/11225): Introduced the [`CKEDITOR.tools.transparentImageData`](http://docs.ckeditor.com/#!/api/CKEDITOR.tools-property-transparentImageData) property which contains transparent image data to be used in CSS or as image source.
+
+Other Changes:
+
+* [#11377](http://dev.ckeditor.com/ticket/11377): Unified internal representation of empty anchors using the [fake objects](http://ckeditor.com/addon/fakeobjects).
+* [#11422](http://dev.ckeditor.com/ticket/11422): Removed Firefox 3.x, Internet Explorer 6 and Opera 12.x leftovers in code.
+* [#5217](http://dev.ckeditor.com/ticket/5217): Setting data (including switching between modes) creates a new undo snapshot. Besides that:
+ * Introduced the [`editable.status`](http://docs.ckeditor.com/#!/api/CKEDITOR.editable-property-status) property.
+ * Introduced a new `forceUpdate` option for the [`editor.lockSnapshot`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-lockSnapshot) event.
+ * Fixed: Selection not being unlocked in inline editor after setting data ([#11500](http://dev.ckeditor.com/ticket/11500)).
+* The [WebSpellChecker](http://ckeditor.com/addon/wsc) plugin was updated to the latest version.
+
+Fixed Issues:
+
+* [#10190](http://dev.ckeditor.com/ticket/10190): Fixed: Removing block style with [`editor.removeStyle()`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-method-removeStyle) should result in a paragraph and not a div.
+* [#11727](http://dev.ckeditor.com/ticket/11727): Fixed: The editor tries to select a non-editable image which was clicked.
+
+## CKEditor 4.3.5
