CKEditor 4 Changelog

CKEditor 4.4.6

Security Updates:

Fixed XSS vulnerability in the HTML parser reported by Maco Cortes.

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!

New Features:

#12501: Allowed dashes in element names in the string format of allowed content rules.
#12550: Added the <main> element to the CKEDITOR.dtd.

Fixed Issues:

CKEditor 4.4

Important Notes:

Marked the editor.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 unless the config.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. Before CKEditor 4.4 widgets were registered to the ACF which was an incorrect behavior (#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 and requiredContent properties for it manually, because the editor will not be able to find them.
The Show Borders plugin was added to the Standard installation package in order to ensure that unstyled tables are still visible for the user (#11665).
Since CKEditor 4.4 the editor instance should be passed to 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 will work even when the editor instance is not provided.

New Features:

#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 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() method for registering custom style handlers.
- The CKEDITOR.style.apply() and CKEDITOR.style.remove() methods are now called with an editor instance instead of the document so they can be reused by the CKEDITOR.editor.applyStyle() and CKEDITOR.editor.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 to make the handling of styles by widgets fully customizable. See: widget.definition.styleableElements, widget.definition.styleToAllowedContentRule, widget.addClass(), widget.removeClass(), widget.getClasses(), widget.hasClass(), widget.applyStyle(), widget.removeStyle(), widget.checkStyleActive().
- Integration with the Allowed Content Filter required an introduction of the CKEDITOR.style.toAllowedContent() method which can be implemented by the custom style handler and if exists, it is used by the CKEDITOR.filter to translate a style to allowed content rules.
#11300: Various changes in the Enhanced Image plugin:
- Introduced the config.image2_captionedClass option to configure the class of captioned images.
- Introduced the config.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: Enhanced Image plugin: It is now possible to add a link to any image type.
#10202: Introduced wildcard support in the Allowed Content Rules format.
#10276: Introduced blacklisting in the Allowed Content Filter.
#10480: Introduced code snippets with code highlighting. There are two versions available so far — the default Code Snippet which uses the highlight.js library and the Code Snippet GeSHi which uses the GeSHi library.
#11737: Introduced an option to prevent filtering of an element that matches custom criteria (see filter.addElementCallback()).
#11532: Introduced the editor.addContentsCss() method that can be used for adding custom CSS files.
#11536: Added the CKEDITOR.tools.htmlDecode() method for decoding HTML entities.
#11225: Introduced the CKEDITOR.tools.transparentImageData property which contains transparent image data to be used in CSS or as image source.

Other Changes:

#11377: Unified internal representation of empty anchors using the fake objects.
#11422: Removed Firefox 3.x, Internet Explorer 6 and Opera 12.x leftovers in code.
#5217: Setting data (including switching between modes) creates a new undo snapshot. Besides that:
- Introduced the editable.status property.
- Introduced a new forceUpdate option for the editor.lockSnapshot event.
- Fixed: Selection not being unlocked in inline editor after setting data (#11500).
The WebSpellChecker plugin was updated to the latest version.

Fixed Issues:

#10190: Fixed: Removing block style with editor.removeStyle() should result in a paragraph and not a div.
#11727: Fixed: The editor tries to select a non-editable image which was clicked.

CKEditor 4.3 Beta

New Features:

#9764: Widget System.
- Widget plugin introducing the Widget API.
- New editor.enterMode and editor.shiftEnterMode properties – normalized versions of config.enterMode and config.shiftEnterMode.
- Dynamic editor settings. Starting from CKEditor 4.3 Beta, Enter mode values and 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 or static Enter mode values depending on whether this feature works in selection context or globally on editor content.
  - Dynamic Enter mode values – editor.setActiveEnterMode() method, editor.activeEnterModeChange event, and two properties: editor.activeEnterMode and editor.activeShiftEnterMode.
  - Dynamic content filter instances – editor.setActiveFilter() method, editor.activeFilterChange event, and editor.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() method.
- Default 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() method.
- Dozens of new methods were introduced – most interesting ones:
  - document.find(),
  - document.findOne(),
  - editable.insertElementIntoRange(),
  - range.moveToClosestEditablePosition(),
  - New methods for htmlParser.node and htmlParser.element.
#10659: New Enhanced Image plugin that introduces a widget with integrated image captions, an option to center images, and dynamic "click and drag" resizing.
#10664: New Mathematical Formulas plugin that introduces the MathJax widget.
