## CKEditor 4.9.2

**Security Updates:**

* Fixed XSS vulnerability in the [Enhanced Image](https://ckeditor.com/cke4/addon/image2) (`image2`) plugin reported
  by [Kyaw Min Thein](https://twitter.com/kyawminthein99).

  Issue summary: It was possible to execute XSS inside CKEditor using the `<img>` tag and specially crafted HTML. Please
  note that the default presets (Basic/Standard/Full) do not include this plugin, so you are only at risk if you made a
  custom build and enabled this plugin.

We would like to thank the [Drupal security team](https://www.drupal.org/drupal-security-team) for bringing this matter
to our attention and coordinating the fix and release process!

  method now allows for skipping bogus `<br>` elements.

Fixed Issues:

  downgraded by the security team into a normal issue due to the requirement of having ACF turned off.
  Disabling [Advanced Content Filter](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_advanced_content_filter.html)
  is
  against [security best practices](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_best_practices.html#security),

## CKEditor 4.5 Beta

New Features:

* Clipboard (copy&paste, drag&drop) and file uploading features and
  improvements ([#11437](https://dev.ckeditor.com/ticket/11437)).

    * Major features:
        * Support for dropping and pasting files into the editor was introduced. Through a set of new facades for native
          APIs it is now possible to easily intercept and process inserted files.
        * [File upload tools](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.fileTools.html) were introduced in
          order to simplify controlling the loading, uploading and handling server response, properly
          handle [new upload configuration](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-uploadUrl)
          options, etc.
        * [Upload Image](https://ckeditor.com/cke4/addon/uploadimage) widget was introduced to upload dropped images. A
          base class for
          the [upload widget](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.fileTools.uploadWidgetDefinition.html)
          was exposed, too, to make it simple to create new types of upload widgets which can handle any type of dropped
          file, show the upload progress and update the content when the process is done. It also handles editing and
          undo/redo operations when a file is being uploaded and integrates with
          the [notification aggregator](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.plugins.notificationAggregator.html)
          to show progress and success or error.
        * All drag and drop operations were integrated with the editor. All dropped content is passed through
          the [`editor#paste`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#event-paste) event
          and a set of new editor events was introduced
          &mdash; [`dragstart`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#event-dragstart), [`drop`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#event-drop), [`dragend`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#event-dragend).
        *
      The [Data Transfer](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.plugins.clipboard.dataTransfer.html)
      facade was introduced to unify access to data in various types and
      files. [Data Transfer](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.plugins.clipboard.dataTransfer.html)
      is now always available in
      the [`editor#paste`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#event-paste) event.
        * Switched from the pastebin to using the native clipboard access whenever possible. This solved many issues
          related to pastebin such as unnecessary scrolling or data loss. Additionally, on copy and cut from the editor
          the clipboard data is set. Therefore, on paste the editor has access to clean data, undisturbed by the
          browsers.
        * Drag and drop of inline and block widgets was integrated with the standard clipboard APIs. By listening to
          drag events you will thus be notified about widgets, too. This opens a possibility to filter pasted and
          dropped widgets.
        * The [`editor#paste`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#event-paste) event
          can have the `range` parameter so it is possible to change the paste position in the listener or paste in the
          not selectable position. Also
          the [`editor.insertHtml()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#method-insertHtml)
          method now accepts `range` as an additional parameter.
        * [#11621](https://dev.ckeditor.com/ticket/11621): A
          configurable [paste filter](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-pasteFilter)
          was introduced. The filter is by default turned to `'semantic-content'` on Webkit and Blink for all pasted
          content coming from external sources because of the low quality of HTML that these engines put into the
          clipboard. Internal and cross-editor paste is safe due to the change explained in the previous point.

    * Other changes and related fixes:
        * [#12095](https://dev.ckeditor.com/ticket/12095): On drag and copy of
          widgets [the same method](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#method-getSelectedHtml)
          is used to get selected HTML as in the normal case. Thanks to that styles applied to inline widgets are not
          lost.
        * [#11219](https://dev.ckeditor.com/ticket/11219): Fixed: Dragging
          a [captioned image](https://ckeditor.com/cke4/addon/image2) does not fire
          the [`editor#paste`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#event-paste) event.
        * [#9554](https://dev.ckeditor.com/ticket/9554): [Webkit Mac] Fixed: Editor scrolls on paste.
        * [#9898](https://dev.ckeditor.com/ticket/9898): [Webkit&Divarea] Fixed: Pasting causes undesirable scrolling.
        * [#11993](https://dev.ckeditor.com/ticket/11993): [Chrome] Fixed: Pasting content scrolls the document.
        * [#12613](https://dev.ckeditor.com/ticket/12613): Show the user that they can not drop on editor UI (toolbar,
          bottom bar).
        * [#12851](https://dev.ckeditor.com/ticket/12851): [Blink/Webkit] Fixed: Formatting disappears when pasting
          content into cells.
        * [#12914](https://dev.ckeditor.com/ticket/12914): Fixed: Copy/Paste of table broken in `div`-based editor.

    * Browser support.<br>Browser support for related features varies significantly (see http://caniuse.com/clipboard).
        * File APIs needed to operate and file upload is not supported in Internet Explorer 9 and below.
        * Only Chrome and Safari on Mac OS support setting custom data items in the clipboard, so currently it is
          possible to recognize the origin of the copied content in these browsers only. All drag and drop operations
          can be identified thanks to the new Data Transfer facade.
        * No Internet Explorer browser supports the standard clipboard API which results in small glitches like where
          only plain text can be dropped from outside the editor. Thanks to the new Data Transfer facade, internal and
          cross-editor drag and drop supports the full range of data.
        * Direct access to clipboard could only be implemented in Chrome, Safari on Mac OS, Opera and Firefox. In other
          browsers the pastebin must still be used.

* [#12875](https://dev.ckeditor.com/ticket/12875): Samples and toolbar configuration tools.
    * The old set of samples shipped with every CKEditor package was replaced with a shiny new single-page sample. This
      change concluded a long term plan which started from introducing
      the [CKEditor SDK](https://ckeditor.com/docs/ckeditor4/latest/examples/index.html)
      and [CKEditor Features Overview](https://ckeditor.com/docs/ckeditor4/latest/features.html) section in the
      documentation which essentially redefined the old samples.
    * Toolbar configurators with live previews were introduced. They will be shipped with every CKEditor package and are
      meant to help in configuring toolbar layouts.

* [#10925](https://dev.ckeditor.com/ticket/10925): The [Media Embed](https://ckeditor.com/cke4/addon/embed)
  and [Semantic Media Embed](https://ckeditor.com/cke4/addon/embedsemantic) plugins were introduced. Read more about the
  new features in the [Embedding Content](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_media_embed.html)
  article.
* [#10931](https://dev.ckeditor.com/ticket/10931): Added support for nesting widgets. It is now possible to insert one
  widget into another widget's nested editable. Note that unless nested
  editable's [allowed content](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_widget_nestedEditable_definition.html#property-allowedContent)
  is defined precisely, starting from CKEditor 4.5 some widget buttons may become enabled. This feature is not supported
  in IE8. Included issues:
    * [#12018](https://dev.ckeditor.com/ticket/12018): Fixed and reviewed: Nested widgets garbage collection.
    * [#12024](https://dev.ckeditor.com/ticket/12024): [Firefox] Fixed: Outline is extended to the left by unpositioned
      drag handlers.
    * [#12006](https://dev.ckeditor.com/ticket/12006): Fixed: Drag and drop of nested block widgets.
    * [#12008](https://dev.ckeditor.com/ticket/12008): Fixed various cases of inserting a single non-editable element
      using
      the [`editor.insertHtml()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#method-insertHtml)
      method. Fixes pasting a widget with a nested editable inside another widget's nested editable.

* Notification system:
    * [#11580](https://dev.ckeditor.com/ticket/11580): Introduced
      the [notification system](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.plugins.notification.html).
    * [#12810](https://dev.ckeditor.com/ticket/12810): Introduced
      a [notification aggregator](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.plugins.notificationAggregator.html)
      for the [notification system](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.plugins.notification.html)
      which simplifies displaying progress of many concurrent tasks.
* [#11636](https://dev.ckeditor.com/ticket/11636): Introduced new, UX-focused, methods for getting selected HTML and
  deleting it
  &mdash; [`editor.getSelectedHtml()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#method-getSelectedHtml)
  and [`editor.extractSelectedHtml()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#method-extractSelectedHtml).
* [#12416](https://dev.ckeditor.com/ticket/12416): Added
  the [`widget.definition.upcastPriority`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_widget_definition.html#property-upcastPriority)
  property which gives more control over widget upcasting order to the widget author.
* [#12036](https://dev.ckeditor.com/ticket/12036): Initialize the editor
  in [read-only](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#property-readOnly) mode when
  the `<textarea>` element has a `readonly` attribute.
* [#11905](https://dev.ckeditor.com/ticket/11905):
  The [`resize` event](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#event-resize) passes the
  current dimensions in its data.
* [#12126](https://dev.ckeditor.com/ticket/12126):
  Introduced [`config.image_prefillDimensions`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-image_prefillDimensions)
  and [`config.image2_prefillDimensions`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-image2_prefillDimensions)
  to make pre-filling `width` and `height` configurable for
  the [Enhanced Image](https://ckeditor.com/cke4/addon/image2).
* [#12746](https://dev.ckeditor.com/ticket/12746): Added a new configuration option to hide
  the [Enhanced Image](https://ckeditor.com/cke4/addon/image2) resizer.
* [#12150](https://dev.ckeditor.com/ticket/12150): Exposed
  the [`getNestedEditable()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_widget.html#static-method-getNestedEditable)
  and `is*` [widget helper](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.plugins.widget.html) functions (see
  the static methods).
* [#12448](https://dev.ckeditor.com/ticket/12448): Introduced
  the [`editable.insertHtmlIntoRange`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editable.html#method-insertHtmlIntoRange)
  method.

  the [`config.floatSpacePreferRight`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-floatSpacePreferRight)
  configuration option that switches the alignment of the floating toolbar. Thanks
  to [InvisibleBacon](http://github.com/InvisibleBacon)!
* [#10986](https://dev.ckeditor.com/ticket/10986): Added support for changing dialog input and textarea text directions
  by using the *Shift+Alt+Home/End* keystrokes. The direction is stored in the value of the input by prepending
  the [`\u202A`](http://unicode.org/cldr/utility/character.jsp?a=202A)
  or [`\u202B`](http://unicode.org/cldr/utility/character.jsp?a=202B) marker to it. Read more in
  the [documentation](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dialog_definition_textInput.html#property-bidi).
  Thanks to [edithkk](https://github.com/edithkk)!
* [#12770](https://dev.ckeditor.com/ticket/12770): Added support for
  passing [widget](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.plugins.widget.html)'s startup data as a
  widget command's argument. Thanks to [Rebrov Boris](https://github.com/zipp3r)
  and [Tieme van Veen](https://github.com/tiemevanveen)!
* [#11583](https://dev.ckeditor.com/ticket/11583): Added support for the HTML5 `required` attribute in various form
  elements. Thanks to [Steven Busse](https://github.com/sbusse)!

Changes:

* [#12858](https://dev.ckeditor.com/ticket/12858):
  Basic [Spartan](http://blogs.windows.com/bloggingwindows/2015/03/30/introducing-project-spartan-the-new-browser-built-for-windows-10/)
  browser compatibility. Full compatibility will be introduced later, because at the moment Spartan is still too
  unstable to be used for tests and we see many changes from version to version.
* [#12948](https://dev.ckeditor.com/ticket/12948):
  The [`config.mathJaxLibrary`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-mathJaxLib)
  option does not default to the MathJax CDN any more. It needs to be configured to enable
  the [Mathematical Formulas](https://ckeditor.com/cke4/addon/mathjax) plugin now.
* [#13069](https://dev.ckeditor.com/ticket/13069): Fixed inconsistencies
  between [`editable.insertHtml()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editable.html#method-insertElement)
  and [`editable.insertElement()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editable.html#method-insertElement)
  when the `range` parameter is used. Now, the `editor.insertElement()` method works on a higher level, which means that
  it saves undo snapshots and sets the selection after insertion. Use
  the [`editable.insertElementIntoRange()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editable.html#method-insertElementIntoRange)
  method directly for the pre 4.5 behavior of `editable.insertElement()`.
* [#12870](https://dev.ckeditor.com/ticket/12870):
  Use [`editor.showNotification()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#method-showNotification)
  instead of `alert()` directly whenever possible. When
  the [Notification plugin](https://ckeditor.com/cke4/addon/notification) is loaded, the notification system is used
  automatically. Otherwise, the native `alert()` is displayed.
* [#8024](https://dev.ckeditor.com/ticket/8024): Swapped behavior of the Split Cell Vertically and Horizontally features
  of the [Table Tools](https://ckeditor.com/cke4/addon/tabletools) plugin to be more intuitive. Thanks
  to [kevinisagit](https://github.com/kevinisagit)!
* [#10903](https://dev.ckeditor.com/ticket/10903): Performance improvements for
  the [`dom.element.addClass()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dom_element.html#method-addClass), [`dom.element.removeClass()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dom_element.html#method-removeClass)
  and [`dom.element.hasClass()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dom_element.html#method-hasClass)
  methods. Note: The previous implementation allowed passing multiple classes to `addClass()` although it was only a
  side effect of that implementation. The new implementation does not allow this.
* [#11856](https://dev.ckeditor.com/ticket/11856): The jQuery adapter throws a meaningful error if CKEditor or jQuery
  are not loaded.

Fixed issues:

* [#11586](https://dev.ckeditor.com/ticket/11586):
  Fixed: [`range.cloneContents()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dom_range.html#method-cloneContents)
  should not change the DOM in order not to affect selection.
* [#12148](https://dev.ckeditor.com/ticket/12148):
  Fixed: [`dom.element.getChild()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dom_element.html#method-getChild)
  should not modify a passed array.
* [#12503](https://dev.ckeditor.com/ticket/12503): [Blink/Webkit] Fixed: Incorrect result of Select All and *Backspace*
  or *Delete*.
* [#13001](https://dev.ckeditor.com/ticket/13001): [Firefox] Fixed: The `<br />` filler is placed in the wrong position
  by the [`range.fixBlock()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dom_range.html#method-fixBlock)
  method due to quirky Firefox behavior.
* [#13101](https://dev.ckeditor.com/ticket/13101): [IE8] Fixed: Colons are prepended to HTML5 element names when cloning
  them.

## CKEditor 4.4.8

**Security Updates:**

* Fixed XSS vulnerability in the HTML parser reported by [Dheeraj Joshi](https://twitter.com/dheerajhere)
  and [Prem Kumar](https://twitter.com/iAmPr3m).

  Issue summary: It was possible to execute XSS inside CKEditor after persuading the victim to: (i) switch CKEditor to
  source mode, then (ii) paste a specially crafted HTML code, prepared by the attacker, into the opened CKEditor source
  area, and (iii) switch back to WYSIWYG mode.

**An upgrade is highly recommended!**

  following IBM CI 162 instructions
  or [ARIA Authoring Practices](http://www.w3.org/TR/2013/WD-wai-aria-practices-20130307/#tabpanel).
* [#12256](https://dev.ckeditor.com/ticket/12256): Fixed: Basic styles classes are lost when pasting from Microsoft Word

## CKEditor 4.4.6

**Security Updates:**

* Fixed XSS vulnerability in the HTML parser reported by [Maco Cortes](https://www.facebook.com/Maaacoooo).

  Issue summary: It was possible to execute XSS inside CKEditor after persuading the victim to: (i) switch CKEditor to
  source mode, then (ii) paste a specially crafted HTML code, prepared by the attacker, into the opened CKEditor source
  area, and (iii) switch back to WYSIWYG mode.

**An upgrade is highly recommended!**

## CKEditor 4.4

**Important Notes:**

* Marked
  the [`editor.beforePaste`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#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](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_advanced_content_filter.html) unless
  the [`config.image2_captionedClass`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#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](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_advanced_content_filter.html).
  Before CKEditor 4.4 widgets were registered to the ACF which was an incorrect
  behavior ([#11567](https://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`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_feature.html#property-allowedContent)
  and [`requiredContent`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_feature.html#property-requiredContent)
  properties for it manually, because the editor will not be able to find them.
* The [Show Borders](https://ckeditor.com/cke4/addon/showborders) plugin was added to the Standard installation package
  in order to ensure that unstyled tables are still visible for the
  user ([#11665](https://dev.ckeditor.com/ticket/11665)).
* Since CKEditor 4.4 the editor instance should be passed
  to [`CKEDITOR.style`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.style.html) 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`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.style.html) will work even
  when the editor instance is not provided.

New Features:

* [#11297](https://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](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_styles.html#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()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_style.html#static-method-addCustomHandler)
      method for registering custom style handlers.
    * The [`CKEDITOR.style.apply()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_style.html#method-apply)
      and [`CKEDITOR.style.remove()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_style.html#method-remove)
      methods are now called with an editor instance instead of the document so they can be reused by
      the [`CKEDITOR.editor.applyStyle()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#method-applyStyle)
      and [`CKEDITOR.editor.removeStyle()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#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](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.plugins.widget.html) to make the handling
      of styles by widgets fully customizable.
      See: [`widget.definition.styleableElements`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_widget_definition.html#property-styleableElements), [`widget.definition.styleToAllowedContentRule`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_widget_definition.html#property-styleToAllowedContentRules), [`widget.addClass()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_widget.html#method-addClass), [`widget.removeClass()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_widget.html#method-removeClass), [`widget.getClasses()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_widget.html#method-getClasses), [`widget.hasClass()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_widget.html#method-hasClass), [`widget.applyStyle()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_widget.html#method-applyStyle), [`widget.removeStyle()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_widget.html#method-removeStyle), [`widget.checkStyleActive()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_widget.html#method-checkStyleActive).
    * Integration with
      the [Allowed Content Filter](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_advanced_content_filter.html)
      required an introduction of
      the [`CKEDITOR.style.toAllowedContent()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_style.html#method-toAllowedContentRules)
      method which can be implemented by the custom style handler and if exists, it is used by
      the [`CKEDITOR.filter`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.filter.html) to translate a style
      to [allowed content rules](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.filter.allowedContentRules.html).
* [#11300](https://dev.ckeditor.com/ticket/11300): Various changes in
  the [Enhanced Image](https://ckeditor.com/cke4/addon/image2) plugin:
    * Introduced
      the [`config.image2_captionedClass`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-image2_captionedClass)
      option to configure the class of captioned images.
    * Introduced
      the [`config.image2_alignClasses`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#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](https://dev.ckeditor.com/ticket/11341): [Enhanced Image](https://ckeditor.com/cke4/addon/image2) plugin: It
  is now possible to add a link to any image type.
* [#10202](https://dev.ckeditor.com/ticket/10202): Introduced wildcard support in

  versions available so far &mdash; the default [Code Snippet](https://ckeditor.com/cke4/addon/codesnippet) which uses
  the [highlight.js](https://highlightjs.org) library and
  the [Code Snippet GeSHi](https://ckeditor.com/cke4/addon/codesnippetgeshi) which uses
  the [GeSHi](http://qbnz.com/highlighter/) library.
* [#11737](https://dev.ckeditor.com/ticket/11737): Introduced an option to
  prevent [filtering](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_advanced_content_filter.html) of an element
  that matches custom criteria (
  see [`filter.addElementCallback()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_filter.html#method-addElementCallback)).
* [#11532](https://dev.ckeditor.com/ticket/11532): Introduced
  the [`editor.addContentsCss()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#method-addContentsCss)
  method that can be used
  for [adding custom CSS files](https://ckeditor.com/docs/ckeditor4/latest/guide/plugin_sdk_styles.html).
* [#11536](https://dev.ckeditor.com/ticket/11536): Added
  the [`CKEDITOR.tools.htmlDecode()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_tools.html#method-htmlDecode)
  method for decoding HTML entities.
* [#11225](https://dev.ckeditor.com/ticket/11225): Introduced
  the [`CKEDITOR.tools.transparentImageData`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_tools.html#property-transparentImageData)
  property which contains transparent image data to be used in CSS or as image source.

Other Changes:

* [#11377](https://dev.ckeditor.com/ticket/11377): Unified internal representation of empty anchors using
  the [fake objects](https://ckeditor.com/cke4/addon/fakeobjects).

      property.
    * Introduced a new `forceUpdate` option for
      the [`editor.lockSnapshot`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#event-lockSnapshot)
      event.
    * Fixed: Selection not being unlocked in inline editor after setting
      data ([#11500](https://dev.ckeditor.com/ticket/11500)).
* The [WebSpellChecker](https://ckeditor.com/cke4/addon/wsc) plugin was updated to the latest version.

  with [`editor.removeStyle()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#method-removeStyle)

## CKEditor 4.3.1

**Important Notes:**

* To match the naming convention, the `language` button is
  now `Language` ([#11201](https://dev.ckeditor.com/ticket/11201)).
* [Enhanced Image](https://ckeditor.com/cke4/addon/image2) button, context menu, command, and icon names match those of
  the [Image](https://ckeditor.com/cke4/addon/image) plugin ([#11222](https://dev.ckeditor.com/ticket/11222)).

  the [`widget.repository.checkWidgets`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_plugins_widget_repository.html#event-checkWidgets)

* [#11204](https://dev.ckeditor.com/ticket/11204): Added `figure` and `figcaption` styles to the `contents.css` file
  so [Enhanced Image](https://ckeditor.com/cke4/addon/image2) looks nicer.
* [#11202](https://dev.ckeditor.com/ticket/11202): Fixed: No newline in [BBCode](https://ckeditor.com/cke4/addon/bbcode)

    * [Widget plugin](https://ckeditor.com/cke4/addon/widget) introducing
      the [Widget API](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.plugins.widget.html).
    * New [`editor.enterMode`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#property-enterMode)
      and [`editor.shiftEnterMode`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#property-shiftEnterMode)
      properties &ndash; normalized versions
      of [`config.enterMode`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-enterMode)
      and [`config.shiftEnterMode`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-shiftEnterMode).
    * Dynamic editor settings. Starting from CKEditor 4.3 Beta, *Enter* mode values
      and [content filter](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_advanced_content_filter.html) 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](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#property-activeEnterMode)
      or [static](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#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()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#method-setActiveEnterMode)
          method, [`editor.activeEnterModeChange`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#event-activeEnterModeChange)
          event, and two
          properties: [`editor.activeEnterMode`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#property-activeEnterMode)
          and [`editor.activeShiftEnterMode`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#property-activeShiftEnterMode).
        * Dynamic content filter instances
          &ndash; [`editor.setActiveFilter()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#method-setActiveFilter)
          method, [`editor.activeFilterChange`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#event-activeFilterChange)
          event,
          and [`editor.activeFilter`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_editor.html#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()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dom_selection.html#method-fake)
      method.
    * Default [`htmlParser.filter`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.htmlParser.filter.html)
      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()`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_htmlParser_filter.html#method-addRules)
      method.
    * Dozens of new methods were introduced &ndash; most interesting ones:

          and [`htmlParser.element`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR.htmlParser.element.html).
* [#10659](https://dev.ckeditor.com/ticket/10659): New [Enhanced Image](https://ckeditor.com/cke4/addon/image2) plugin

**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](https://ckeditor.com/cke4/addon/indentblock) plugin. Because of this
  the [Advanced Content Filter](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_advanced_content_filter.html) might
  remove block indentations from existing contents. If you want to prevent this,
  either [add an appropriate ACF rule to your filter](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_allowed_content_rules.html)

## CKEditor 4.1 RC

New Features:

* [#9829](https://dev.ckeditor.com/ticket/9829): Advanced Content Filter - data and features activation based on editor

  Brand new data filtering system that works in 2 modes:

    * Based
      on [`config.allowedContent`](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-allowedContent)
      rules - the data
      will be filtered and the editor features (toolbar items, commands, keystrokes) will be enabled if they are
      allowed.

  See the `datafiltering.html`
  sample, [guides](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_advanced_content_filter.html)

  before writing structure to an HTML string.

    * Introduced

      property to make it easier to check the current status of the editor.
