Release highlights

We are happy to announce the release of CKEditor 5 v32.0.0.

This release introduces the following new features:



  • engine: Batch#type has been deprecated. It will always return 'default' value and reading it will log a warning in the console. Use Batch#isUndoable, Batch#isLocal, Batch#isUndo and Batch#isTyping instead.
  • revision-history: Multiple changes to Revision properties has been introduced that impact revision history integrations. Introduced #fromRevision and #toRevision properties. Renamed #data to #diffData. The #isLocked property has been removed. Those changes have an impact on what data should be saved in your database and how the revision history plugin should be integrated. Please refer to the migration guide and the documentation to learn more about these changes.
  • revision-history: The RevisionHistoryAdapter interface has changed. Also, RevisionTracker no longer uses RevisionHistoryAdapter#getRevisions() to fetch revisions during editor initialization. You should add revisions data in your integration plugin. Please refer to the migration guide and the documentation to learn how to update your revision history integration.
  • revision-history: RevisionTracker#updateRevision() has been removed while #update() and #saveRevision() have been introduced instead. This, among others, may have an impact on your autosave integration. Please refer to the migration guide and the documentation to learn how to update your revision history integration.
  • typing: Input#isInput() has been removed. Use Batch#isTyping instead.
  • Upgraded the minimal versions of Node.js to 14.0.0 due to the end of LTS.


  • engine: The string value for the Batch type and Model#enqueueChange() is now deprecated. Using a string value will log a warning in the console. Use an object value instead. For more information, refer to the API documentation.
  • revision-history: RevisionTracker#isLocked has been removed.
  • revision-history: The flow for creating and updating a revision has changed. See documentation to learn what it looks like after the changes.
  • The previously named #_getTemplate() methods in CommentThreadView, CommentView, and SuggestionThreadView were renamed to #getTemplate(). These methods are used in annotations customization, when changing the default templates.


  • autosave: Autosave#save() will now return a promise that is resolved when the autosave callback has finished. (commit)
  • comments: Introduced Annotation#refreshVisibility() and Annotations#refreshVisibility() that refresh the visibility of the annotations based on the visibility of their target elements.
  • comments: Introduced the Annotation#isVisible observable property, that allows controlling the visibility of the annotation.
  • html-support: Added support for the <script> elements. Closes #10891. (commit)
  • list: Implemented the numbered list properties UI. Closes #10877. (commit)
  • list: Added support for reversed lists and list start index (reversed and start HTML attributes). Closes #10673. (commit)
  • paste-from-office: Added support for start index in ordered lists. Closes #11043. (commit)
  • revision-history: Introduced Revision#fromVersion and Revision#toVersion.
  • revision-history: Introduced new methods in RevisionHistory plugin: #addRevisionData(), #getRevision(), #getRevisions().
  • ui: Introduced the InputNumberView class and the createLabeledInputNumber() helper for creating number inputs (see #10877). (commit)
  • ui: Introduced the InputView class for other inputs such as InputTextView to inherit from (see #10877). (commit)
  • utils: Introduced the isVisible() helper to detect whether DOM elements are visible to the user in DOM (see #10877). (commit)
  • Replaced Batch#type with a set of flags: Batch#isUndoable, Batch#isLocal, Batch#isUndo, Batch#isTyping which better represent the batch type. The Batch constructor and Model#enqueueChange() now expect an object. Closes #10967. (commit)

Bug fixes

  • comments: DOM listeners will be detached when destroying annotation collections which prevents memory leaks.
  • engine: HTMLDataProcessor#toView() should preserve leading non-layout elements while loading partial HTML. Closes #11110. (commit)

  • mention: The mention plugin now allows searching mentions that include space characters. Closes #9741. (commit)
  • pagination: The page number input view should not stretch. Used InputNumberView to render the page number input in PageNavigatorView.
  • revision-history: Fixed a crash when a revision contained overlapping suggestions.
  • revision-history: Fixed a crash when content selected by triple-click was copy-pasted into the editor.
  • track-changes: Fixed a crash that was happening during real-time editing when one of the users used enter inside a suggestion.
  • typing: Fixed editor crash when an unrecognized transformation was given in configuration (as a string). (commit)
  • watchdog: Prevented EditorWatchdog from crashing during the editor destruction process when one of the plugins tries to change data at that moment. Closes #10643. (commit)
