## 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 (`<figure class="caption">`) 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 &mdash; `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).

## CKEditor 4.3 Beta

New Features:

* [#9764](http://dev.ckeditor.com/ticket/9764): Widget System.
  * [Widget plugin](http://ckeditor.com/addon/widget) introducing the [Widget API](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.widget).
  * New [`editor.enterMode`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-property-enterMode) and [`editor.shiftEnterMode`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-property-shiftEnterMode) properties &ndash; normalized versions of [`config.enterMode`](http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-enterMode) and [`config.shiftEnterMode`](http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-shiftEnterMode).
  * Dynamic editor settings. Starting from CKEditor 4.3 Beta, *Enter* mode values and [content filter](http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter) instances may be changed dynamically (for example when the caret was placed in an element in which editor features should be adjusted). When you are implementing a new editor feature, you should base its behavior on [dynamic](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-property-activeEnterMode) or [static](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-property-enterMode) *Enter* mode values depending on whether this feature works in selection context or globally on editor content.
      * Dynamic *Enter* mode values &ndash; [`editor.setActiveEnterMode()`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-method-setActiveEnterMode) method, [`editor.activeEnterModeChange`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-activeEnterModeChange) event, and two properties: [`editor.activeEnterMode`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-property-activeEnterMode) and [`editor.activeShiftEnterMode`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-property-activeShiftEnterMode).
      * Dynamic content filter instances &ndash; [`editor.setActiveFilter()`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-method-setActiveFilter) method, [`editor.activeFilterChange`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-activeFilterChange) event, and [`editor.activeFilter`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-property-activeFilter) property.
  * "Fake" selection was introduced. It makes it possible to virtually select any element when the real selection remains hidden. See the  [`selection.fake()`](http://docs.ckeditor.com/#!/api/CKEDITOR.dom.selection-method-fake) method.
  * Default [`htmlParser.filter`](http://docs.ckeditor.com/#!/api/CKEDITOR.htmlParser.filter) rules are not applied to non-editable elements (elements with `contenteditable` attribute set to `false` and their descendants) anymore. To add a rule which will be applied to all elements you need to pass an additional argument to the [`filter.addRules()`](http://docs.ckeditor.com/#!/api/CKEDITOR.htmlParser.filter-method-addRules) method.
  * Dozens of new methods were introduced &ndash; most interesting ones:
      * [`document.find()`](http://docs.ckeditor.com/#!/api/CKEDITOR.dom.document-method-find),
      * [`document.findOne()`](http://docs.ckeditor.com/#!/api/CKEDITOR.dom.document-method-findOne),
      * [`editable.insertElementIntoRange()`](http://docs.ckeditor.com/#!/api/CKEDITOR.editable-method-insertElementIntoRange),
      * [`range.moveToClosestEditablePosition()`](http://docs.ckeditor.com/#!/api/CKEDITOR.dom.range-method-moveToClosestEditablePosition),
      * New methods for [`htmlParser.node`](http://docs.ckeditor.com/#!/api/CKEDITOR.htmlParser.node) and [`htmlParser.element`](http://docs.ckeditor.com/#!/api/CKEDITOR.htmlParser.element).
* [#10659](http://dev.ckeditor.com/ticket/10659): New [Enhanced Image](http://ckeditor.com/addon/image2) plugin that introduces a widget with integrated image captions, an option to center images, and dynamic "click and drag" resizing.
* [#10664](http://dev.ckeditor.com/ticket/10664): New [Mathematical Formulas](http://ckeditor.com/addon/mathjax) plugin that introduces the MathJax widget.
* [#7987](https://dev.ckeditor.com/ticket/7987): New [Language](http://ckeditor.com/addon/language) plugin that implements Language toolbar button to support [WCAG 3.1.2 Language of Parts](http://www.w3.org/TR/UNDERSTANDING-WCAG20/meaning-other-lang-id.html).
* [#10708](http://dev.ckeditor.com/ticket/10708): New [smileys](http://ckeditor.com/addon/smiley).

**Important Notes:**

* Dropped compatibility support for Internet Explorer 7 and Firefox 3.6.

* Both the Basic and the Standard distribution packages will not contain the new [Indent Block](http://ckeditor.com/addon/indentblock) plugin. Because of this the [Advanced Content Filter](http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter) might remove block indentations from existing contents. If you want to prevent this, either [add an appropriate ACF rule to your filter](http://docs.ckeditor.com/#!/guide/dev_allowed_content_rules) or create a custom build based on the Basic/Standard package and add the Indent Block plugin in [CKBuilder](http://ckeditor.com/builder).

  current configuration can handle.

  will be filtered and the editor features (toolbar items, commands, keystrokes) will be enabled if they are allowed.
