## 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:
