We are happy to announce the release of CKEditor 5 v42.0.0.

Release highlights

New installation methods

We are excited to announce the latest release of CKEditor 5, bringing major improvements to simplify the installation and setup process. After extensive research and gathering feedback, we have improved the setup methods to enhance the developer experience and align with modern standards.

The most prominent changes:

  • All plugins and core features are now available from the unified ckeditor5 and ckeditor5-premium-features packages, reducing dependency management complexity.
  • Our packages became bundler-agnostic. You can use whatever bundler you want (such as Vite or esbuild), to integrate CKEditor 5.
  • CSS files are now distributed separately from JavaScript, allowing for parallel downloading, easier customization, and improved performance.
  • All the new distribution methods (available via npm, CDN, and ZIP downloads) allow dynamic plugin registration making it easy to add or remove plugins dynamically.

The old installation methods are still supported, but we put them on the deprecation path. Read more about this in our migration guides.

New Builder

Along with the new release, we present you the brand new CKEditor 5 Builder.

The new Builder allows you to start with one of the predefined presets, customize it by adding and removing features, and observe the changes live in an editor preview (and play with the editor!). Once you are happy with your custom setup, you get ready-to-use code snippets for React, Angular, Vue, and VanillaJS setups for both npm and CDN distributions.

Updated documentation

We rewrote large parts of the documentation to complete the picture and ensure consistency across the ecosystem. The entire Getting started section was redesigned to focus on the new installation methods and to better guide the integrator through the ecosystem.

If you need clarification or a more in-depth explanation, please let us know.

Migration paths

Finally, detailed migration guides can be found in our documentation. These guides provide step-by-step instructions and examples to help you seamlessly transition to the new installation methods:

We value your input, so please share your experiences, ask questions, and provide feedback to help us refine these changes. Join us in this exciting new chapter for CKEditor 5 and let’s make the developer experience as smooth and enjoyable as possible.

Removal of superbuild and predefined builds from the CDN

We have stopped publishing the superbuild and predefined builds to our CDN. Predefined builds can still be accessed as an npm package. If you want to keep using our CDN with new versions of the editor, we recommend migrating to the new installation methods.

Other updates

We are excited to announce a major update to our premium Export to Word feature, delivering significantly improved quality with multiple enhancements and bug fixes. This release also brings a substantial reduction in the conversion time. Export to Word v2 is an opt-in feature right now, and to use it you need to slightly change the editor’s configuration. Detailed information can be found in the documentation.

MINOR BREAKING CHANGES ℹ️

  • image: The Insert image via URL UI component form has been moved to a modal dialog instead of being available directly in the insert image dropdown.
  • image: Increased specificity of the .image-style-block-align-[right/left], .image-style-align-[right/left], and .image-style-side CSS classes by adding the .image class. See #16317.
  • media-embed: The media embed feature now uses a modal dialog (instead of a toolbar dropdown) for inserting media.
  • pagination: If you have custom CSS styles that override the default styling of the Pagination elements, they might stop working after this change. The reason is that a stricter CSS selector with ck-pagination-loaded is now used to hide or show these elements.

Features

  • engine: Schema now supports disallowing items. Introduced the SchemaItemDefinition#disallowIn, SchemaItemDefinition#disallowChildren and SchemaItemDefinition#disallowAttributes properties. Closes #15835. (commit)
  • engine: Introduced the DiffItemInsert#action, DiffItemInsert#before and DiffItemRemove#action properties which give more information about the change that happened in the model. Refer to the API documentation to learn more. Closes #15800. (commit)
  • export-word: Added support for Export to Word API v2.
  • image: Added menu bar integration for the insert image component. The menuBar:insertImage component is by default added to the "Insert" menu and replaces current buttons related to image insertion. Closes #16445. (commit)
  • list-multi-level: Added the menu bar integration for multi-level lists. The menuBar:multiLevelList component is by default added in the "Format" menu.
  • media-embed: Added menu bar integration to media embed. The "Media" button is now available in the "Insert" menu. (commit)

Bug fixes

  • ckeditor5-premium-features: Use the new @ckeditor/ckeditor-cloud-services-collaboration build targeting es2022 when creating a browser build of ckeditor5-premium-features.
  • comments: Prevent crashes in narrow and wide sidebars when the EditorAnnotations plugin is not loaded.

  • pagination: The PageBreak and Pagination plugin styles no longer conflict. Closes #16506.
  • real-time-collaboration: Long user names should render correctly in the collapsed presence list when the config.presenceList.onClick configuration is set.

  • ui: Fixed incorrect position of the block toolbar tooltip handle. Closes #16365. (commit)
  • ui: Prevented an editor error in a situation where tooltip was unpinned after it was already removed. This happened when the "Unlink" button was pressed while the tooltip was shown. (commit)
  • ui: The TooltipManager tooltips should immediately show up when triggered by user focus for better responsiveness and accessibility. (commit)
  • Add declare to dynamically populated class fields. Closes #16386. (commit)
