Release highlights

Complete documentation redesign is here

We have prepared a new theme for our documentation to enhance its quality. The new look improves readability and addresses several accessibility issues for a better experience. The redesigned navigation bar gives more useful access to various sections of the documentation, making it easier to reference guides for all our products. Improved table of contents makes browsing and finding guides easier, paired with updated search functionality. Check out the new experience yourself!

The pagination plugin just got better

This release introduces a significant pagination update, along with numerous fixes. Page breaks are now calculated taking into account the content styles, bookmark markers, and with better tolerance calculation. Pagination now also finds the correct breakpoint for large tables of contents and images taller than the page.

Table handling with pagination and export to PDF

The pagination and export to PDF features now better support tables containing one or more paragraphs. Cell margins are now correctly applied in exported tables, which improves the precision of pagination rendering.

Bug fixes

  • export-word, list-multi-level, real-time-collaboration, revision-history, track-changes: Fixed a bug that caused TypeScript to report compilation errors in .d.ts files (e.g. Module has no exported member) when adding the ckeditor5-premium-features dependency to a project that installs CKEditor 5. The issue was caused by TypeScript compilation problems in the ckeditor5-premium-features package and affected users who didn't have "skipLibCheck": true set in their tsconfig.json.
  • export-pdf, pagination: The pagination and export to PDF features now better support tables containing one or more paragraphs. Cell margins are now correctly applied in exported tables, which improves the precision of pagination rendering.
  • comments, track-changes: Annotations will now be hidden in the sidebar when the target element is not a valid DOM element, preventing sidebar flickering and the appearance of orphaned annotations.
  • comments: Resolved comment thread highlight will now be properly removed from the editing area when the comments archive is closed while the editor is in read-only mode.
  • comments: Fixed CommentsEditing being exported as type instead of value.
  • html-support: Fixed following plugins being exported as types instead of values: CodeBlockElementSupport, CustomElementSupport, ListElementSupport, DualContentModelElementSupport, HeadingElementSupport, ImageElementSupport, MediaEmbedElementSupport, ScriptElementSupport, StyleElementSupport, TableElementSupport, HorizontalLineElementSupport. Closes #18855.
  • list: Fix the vertical spacing of a single paragraph in the list item with a nested list. Closes #18831.
  • pagination: Pagination correctly handles content styles like .ck-content > :first-child.
  • pagination: Pagination lines do not change position depending on user selection.
  • pagination: Pagination correctly finds page breaks on a large table of contents.
  • pagination: The pagination line is correctly positioned when there is a bookmark element at the start of the block.
  • pagination: Pagination can find page breaks on images taller than a page height.
  • paste-from-office: Clean the width: 0 attribute when tables are pasted from Word.
  • revision-history: Fixed RevisionViewerIntegration being exported as type instead of value.
  • table: Tables should not be stretched to full page width when printed.
  • table: The table caption should not be scrambled when the document is printed. Closes #18903.
  • track-changes: Fixed multiple cases where suggestion markers were created on incorrect ranges, causing sidebar flickering.
  • track-changes: Fixed TrackChangesUI missing an export.
  • utils: Fixed the Identifier 'global' has already been declared. error being thrown in some environments due to the global variable name in the @ckeditor/ckeditor5-utils package. Closes #18856.

Other changes

  • collaboration-core: Make CollaborationUserColor#id a public readonly property.
  • emoji: Improve the initialization performance of the Emoji feature by optimizing the EmojiUtils#isEmojiSupported() method. Closes #18822.
  • export-pdf: Added width constraint for content exported to PDF.
  • image: Image caption should be printed on the same page as the image.
  • pagination: Pagination uses 0.5mm tolerance while calculating line breaks.

46.0.0 (July 9, 2025)

We are happy to announce the release of CKEditor 5 v46.0.0.

Release highlights

[!IMPORTANT] This is a major release with significant amount of changes that may affect your CKEditor 5 integration. We strongly encourage you to read the entire update guide to understand all the changes. Pay special attention to:

Line Height (⭐)

The new Line Height feature allows you to adjust the vertical spacing between lines of text, improving readability and visual harmony in your documents. This premium feature lets you set consistent line spacing across paragraphs and text blocks to enhance document accessibility and maintain visual hierarchy in your content.

Remove Format improvements

Unneeded styles on block elements, such as tables and images, and General HTML Support nodes and attributes are finally eliminated when you hit the remove format button. The feature now cleans what it should, leaving the document structure untouched.

List markers styling

Working with styled lists becomes more intuitive as list markers (bullets and numbers) now automatically inherit text styling properties such as font size adjustments, text color changes, and font weight modifications (bold, italic).

This improvement makes it easier to create visually consistent and professional-looking lists without additional configuration. This improvement also supports Multi-level lists.

Important! This behavior is enabled by default, which means you may experience content change when you load the content to the editor 's new version (for the better in our opinion). But if this is not something you expect, you can opt out.

Markdown processor dependency refresh

The Markdown feature dependencies have been modernized with a switch to the unified ecosystem, replacing the previous marked / turndown implementation. This change brings more consistent and symmetrical HTML ↔ Markdown conversion. By adopting remark and rehype from the same family of tools, we have created a more reliable and maintainable implementation that will better serve your document processing needs.

Manual token refreshing

We have added the config.cloudServices.autoRefresh configuration property to disable the automatic token refresh mechanism. When it 's set to false, the token must be refreshed manually. This property opens up the ability to implement custom token handling if a certain use case requires this.

Comment threads improvements

New thread command changes

We have also introduced improvements to the addCommandThread command, which now supports creating comment threads on specified ranges. Additionally, it allows for creating a comment thread with an initial comment with the provided comment content.

Minor breaking change The AddCommandThreadCommand#isEnabled property is no longer false when the current document selection is empty, as the command now allows for creating comment threads on custom ranges. If you previously used this property (for example, to provide a custom UI element), you should now use the observable AddCommentThreadCommand#hasContent property instead.

Comments and suggestions annotations

We have introduced dedicated methods for an easier way to get specific annotations related to a comment or a suggestion and vice versa.

Unified exports and renames in the editor API

After the big New Installation Method release (v42.0.0+), some developers upgrading from v41-x to v42-x were greeted by the does not provide an export named ... error. We addressed issues immediately as they were reported, but we knew it required a deeper are more comprehensive approach long-term.

With this release, we introduced a new, clear set of rules about internal imports, and also added re-exports if they were missing, changed the names of items to be more descriptive and avoid collisions, took care of internal methods that were already exported but not tagged, and cleaned up @deprecated code that was stale for some time.

If your build throws errors after the update, search and replace the old names with the new ones from the update guide. We have not changed the behavior of these APIs, just the names.

Last but not least, this release put us on the clean and straight path towards the deprecation of old installation methods. Please let us know if you have any questions on GitHub or support channels.

Opinionated default content styles and CSS renames

To improve the out-of-the-box experience and accessibility, we are introducing opinionated defaults for content styling. From this version, we ship a small defaults layer applied to .ck-content. These content styles are easily replaceable via CSS variable override. You may have already styled those things with more specific selectors.

While working on this initiative, we decided to standardize the CSS naming, too. All older variables that applied to the content styles now share the consistent --ck-content-* prefix. Read about the details in the update guide.

MAJOR BREAKING CHANGES ℹ️

  • ai: The AI Assistant now uses the more advanced gpt-4o model by default, replacing the previous gpt-3.5-turbo. This update improves response quality and overall capabilities. Additionally, the default limit set by max_tokens parameter has been removed, allowing for better and more detailed responses. If you relied on the previous default settings and wish to continue using them, be sure to explicitly define the editor configuration entry ai.openAi.requestParameters to { model: 'gpt-3.5-turbo', max_tokens: 2000, stream: true }.
  • document-outline: Content area CSS variables have been renamed to use the --ck-content-* prefix for better consistency in the Table of Contents feature. This requires action if you have overridden the variables. See the update guide for details.
  • list: Removed vertical spacing in list items by resetting margins for <p> elements that are the child of a <li> element.
  • table: Removed vertical spacing in table cells by collapsing margins of

    elements that are the only child of a <td> or <th> element.

  • The editor now enforces default browser styles for text content in both the editing view and rendered output. This change may affect existing styling and layout, so any custom CSS overrides should be reviewed. See #18710 for details. The following CSS variables and their default values are now applied:
    • --ck-content-font-family: Helvetica, Arial, Tahoma, Verdana, sans-serif
    • --ck-content-font-size: medium
    • --ck-content-font-color: #000 (HEX instead of hsl() to ensure compatibility with email clients)
    • --ck-content-line-height: 1.5
    • --ck-content-word-break: break-word
  • The default styles for comment annotations have changed to provide better consistency with the editor UI. A new set of CSS variables is now used to control the appearance of the comment content and input fields. These changes may affect the current appearance of comments in your integration, so please review them after updating. The following CSS variables are now applied:

    • --ck-comment-content-font-family
    • --ck-comment-content-font-size
    • --ck-comment-content-font-color (default changed from hsl(0, 0%, 0%) to hsl(0, 0%, 20%))

    These variables default to values derived from the editor 's UI styles, and they may differ from your current settings. Customize these variables as needed to match your desired appearance.

  • Content area CSS variables have been renamed to use the --ck-content-* prefix for better consistency in the Highlight, Image, List, and Table features. This requires action if you have overridden the variables. See the update guide for details.
  • Table-related CSS variables with improper *-selector-* naming have been renamed to use *-table-* for better clarity. This requires action if you have overridden the variables. See the update guide for details.

MINOR BREAKING CHANGES ℹ️

  • comments: The AddCommandThreadCommand#isEnabled property is no longer false when the current document selection is empty, as the command now allows for creating comment threads on custom ranges. If you previously used this property (for example, to provide a custom UI element), you should now use the observable AddCommentThreadCommand#hasContent property instead.
  • core: Removed the deprecated DataApiMixin function and DataApi interface. Their functionality is the part of the Editor class.
  • engine: Removed Batch#type deprecated property.
  • list: Removed DocumentList, DocumentListProperties and TodoDocumentList plugins. They were aliases for plugins List, ListProperties and DocumentList respectively.
