Latest

The CKEditor 5 v45.0.0 release brings powerful new features and improvements, making content creation smoother and more versatile. From enhanced email editing to a refined linking experience and a brand-new full-screen mode, this update is packed with valuable upgrades.

Release highlights

Email editing enhancements

We are making it easier to create and edit emails directly in CKEditor 5 with several enhancements. This release introduces the following new features:

  • Export with Inline Styles (⭐) provides the ability to export email content with automatically inlined styles, ensuring compatibility and proper rendering across different email clients.
  • Email Configuration Helper (⭐) is a new configuration helper plugin that provides guidance for integrators to correctly set up an email-friendly editor while avoiding common pitfalls.
  • Layout tables: are a new type of tables that has been introduced to simplify the creation of structured email designs, offering better control over layout, alignment and spacing.

Apart from these new features, this update also brings various fixes and improvements related to table behavior, enhanced HTML support, and better handling of complex email structures. These refinements help ensure a more seamless email editing experience, reducing inconsistencies and improving compatibility with external email clients.

The fullscreen feature

A long-requested feature has finally arrived with the introduction of full-screen editing for the classic and decoupled editor types. This new mode provides a focused writing experience by making the editor the centerpiece of the screen. The expanded screen space allows for better visibility of content in sidebars such as comments, suggestions, and document outlines, enhancing your overall workflow.

Improved linking experience

Linking in CKEditor 5 has been significantly upgraded with a redesigned user interface, making adding and editing links more intuitive. We added the possibility to add and edit the display text of a link. Users can now easily link to bookmarks within the document and select links from predefined lists (defined by the developer). These improvements make inserting and managing links faster and more flexible than ever before.

During this initiative, we also aligned visual and technical components of the editor. Each balloon got a header with the tile, we also unified the toolbar behavior and keystrokes of Link and Bookmarks with other widget’s toolbars like image and tables.

Note

The UI got updated in several places: main view, link properties (decorators), and also its technical implementation changed. Make sure to give special attention to the update if you did any customizations to the link interface.

New installation methods improvements: icons replacement

We are continuing to strengthen the new installation methods while phasing out older solutions. We added one of the key components you asked for: replacing our icons with your custom ones. It is now possible to replace the icons via the package’s override mechanism.

Note

To achieve a proper solution for icons replacement for the npm builds, we needed to introduce a breaking change. If you used our icons for any purposes, make sure to update their paths.

⚠️ Deprecations in old installation methods: stage 1 completed

We are progressing with deprecation according to our sunset plan. From this release, predefined builds’ packages, such as @ckeditor/ckeditor-build-classic, are now officially deprecated.

We also dropped support for Webpack 4 in both the old and new installation methods. All packages and CDN from this version are now distributed with ES2022 as the target ECMAScript version, providing better compatibility with modern JavaScript features and improved performance.

By the end of 2025, custom builds that rely on webpack and DLL builds will also be deprecated. Refer to our documentation and migration guides to ensure a smooth transition.

We are committed to making CKEditor 5 even better. Stay tuned for more improvements in upcoming releases! If you have any feedback, let us know — we are always listening.

Please refer to the update guide to learn more about these changes.

Happy editing!

MAJOR BREAKING CHANGES ℹ️

  • bookmark: The BookmarkUI#actionsView is no longer available. The bookmark feature is now using the WidgetToolbarRepository instead.
  • build-*: CKEditor 5 predefined builds are no longer available.
  • link: The LinkUI#actionsView is no longer available. The bookmark feature now uses the LinkUI#toolbarView (an instance of the ToolbarView class) instead of the custom LinkActionsView.

MINOR BREAKING CHANGES ℹ️

  • link: The createBookmarkCallbacks() helper is now replaced by the isScrollableToTarget() and scrollToTarget() helpers.
  • table: The FormRowView class was moved to the @ckeditor/ckeditor5-ui package.
  • table: The form.css component was moved to the @ckeditor/ckeditor5-theme-lark package.
  • All CKEditor 5 icons are now available in the @ckeditor/ckeditor5-icons package.

DISTRIBUTION CHANGES

  • All packages and CDN source code now target ES2022 as the ECMAScript version.

Features

  • email: Introduced a new package to validate the editor configuration for email compatibility. It helps prevent misconfigurations by enforcing best practices and future-proof rules. Added utilities for post-processing CSS, improving support across various email clients by adjusting styles for better rendering consistency.
  • export-inline-styles: Added a new package for exporting content with inline styles. Ensures CSS classes ([class]) and IDs ([id]) are inlined within elements, improving compatibility with email clients that strip external styles. It helps maintain consistent formatting across different email clients, reducing rendering issues.
  • fullscreen: Introduced the fullscreen mode feature. Closes #18026. (commit)
  • html-support: Introduced the ability to render the<style> elements from the <head> section of editor data content using the FullPage plugin. See #13482. (commit)
  • revision-history: Added a new property RevisionHistory#isRevisionViewerOpen that indicates whether the revision history is opened or not.
  • source-editing-enhanced: The one-dark theme is now built-in and available via config.sourceEditingEnhanced.theme by passing the 'dark' value. This change enables the use of the dark theme with the CDN installation method, which does not support external CodeMirror dependencies. Additionally, if you previously used the oneDark extension directly, you can now switch to theme: 'dark' for built-in support.
  • table: Introduced the layout tables feature to enable constructing grids with tables, for example for email editing. These tables are designed for layout purposes, and include the role="presentation" parameter for accessibility. Users can insert layout tables via the editor toolbar and switch between content and layout tables. The editing view now closely matches the rendered output. Closes #18132. (commit)
  • table: Added the ability to toggle between content tables and layout tables. Users can switch table types using a split button in the table properties UI. While captions and <th> elements may be lost, table structure remains intact. Closes #18131. ([commit](https://github.com/...

v44.3.0

We are happy to announce the release of CKEditor 5 v44.3.0.

Release Highlights

This release brings a couple of minor improvements and bug fixes:

  • Link Decorators: We fixed the behavior of the multiple manual link decorators that set the rel attribute. The fix happened so deep in the engine that we improved the overall performance of the editor slightly as well.
  • Added a new EmptyBlock plugin: From now on, new plugin prevents adding &nbsp; to the output data of blocks, works similarly to the fillEmptyBlocks configuration in CKEditor 4.
  • Support for the <hr> element in the General HTML Support plugin enhanced: attributes of the <hr> element are now properly preserved if configuration allows it.
  • Emoji: We enhanced emoji support for better compatibility with users' older devices.

For more details, see the changelog below.

MINOR BREAKING CHANGES ℹ️

  • engine: The ViewConsumable.consumablesFromElement() is removed and replaced with the view.Element#_getConsumables() internal method. You should use ViewConsumable.createFrom() to create consumables if needed.
  • engine: The ViewElementConsumables now accepts and outputs only normalized data. The ViewConsumable still accepts normalized or non-normalized input.
  • engine: The Matcher#match() and Matcher#matchAll() output is now normalized. The MatchResult#match now contains normalized data compatible with changes in the ViewConsumable.

Features

Bug fixes

  • collaboration-core: User initials will now be generated based on the words that start with letters, ensuring that only valid alphabetic characters are used in the initials.
  • comments: Annotations will no longer be lost during real-time collaboration when a user removes and immediately reverts (undo) content containing comment markers.
  • comments: The editor will no longer crash when one user removes content containing a comment that another user is editing.
  • engine: The link [rel] attribute will now allow mixing manual link decorators for the same attribute, as it will be now handled as a token list. Closes #13985, Closes #6436. (commit)
  • mention: Mention should not be wrapped with an additional <span> when GHS is enabled. Closes #15329. (commit)
  • ui: Fixed an issue where the first selected color was applied instead of the second selected color when using the font color picker for the first time after loading the page. Closes #17069. (commit)
  • typing: Removing a nested editable does not remove an entire widget when the selection is placed at the beginning of that element. (commit)

Other changes

  • clipboard: Export the viewToPlainText() function. Closes #17950. (commit)
  • collaboration-core: Introduced a new configuration option: config.users.getInitialsCallback. It allows providing a custom callback function for user initials generation.
  • emoji: Improved emoji support by expanding the range of versions compatible with users' devices. Closes #18014. (commit)
  • emoji: Icons representing categories in the grid come from the same Unicode version to avoid rendering the non-supported ones. (commit)
  • emoji: Introduced the emoji.useCustomFont option to disable the filtering mechanism. Closes #18029. (commit)
  • engine: The whitespaces around a block filler (&nbsp;) are ignored while loading editor data. (commit)

v44.2.1

We are happy to announce the release of CKEditor 5 v44.2.1.

During a recent internal audit, we identified a cross-site scripting (XSS) vulnerability in the CKEditor 5 real-time collaboration package (CVE-2025-25299). This vulnerability can lead to unauthorized JavaScript code execution and affects user markers, which represent users' positions within the document.

This vulnerability affects only installations with real-time collaborative editing enabled.

You can read more details in the relevant security advisory and contact us if you have more questions.

Bug fixes

  • comments: Fixed a few scenarios for which creating a new comment thread was impossible (for example, when a selection was made on multiple table cells). This was a regression introduced in v44.2.0.

v44.2.0

We are happy to announce the release of CKEditor 5 v44.2.0.

Release Highlights

🖥️ Enhanced Source Code Editing (⭐)

Introducing new premium feature: Enhanced Source Code Editing. It displays the source code in a dialog and is compatible with all editor types. It offers syntax highlighting, code completion, code folding, and other advanced functionalities. Additionally, it supports both HTML and Markdown formats.

📤 Uploadcare and image optimizer (⭐)

We have integrated the Uploadcare image manager service, enabling you to upload and edit images to their cloud environment. You can upload files from various sources, including local devices, social media, or online drives ensuring rapid uploads. The integration takes care of efficient media delivery with responsive images mechanism, making sure your users will save bandwidth and have faster website loading. You can also optimize images with the built-in image editor which offers a range of features, such as cropping, rotating, flipping, photo filters and more. All this directly from the editor, try it out!

🖼️ Image Merge Fields (⭐)

Image merge fields are a new type of merge fields, dedicated for image placeholders. They maintain all standard image interactions, like styling, resizing or captions (in which you can use merge fields too!) At the same time, they keep all merge fields functionalities, like data previews or document export integration. In the document data, image merge fields are represented like other images, however their src attribute is set to a respective merge field, for example, src="{{CompanyLogo}}", making them easy to post-process!

📝 Track Changes Preview (⭐)

We have added the preview mode that displays a document with all suggestions accepted. Accessible from the track changes dropdown, this modal preview helps check the final content without extensive markers.

😀 Emoji support

They are here! 🎉 🥳 🎊 Insert emojis effortlessly in the editor by typing : or through a user-friendly emoji picker. This feature enhances the richness of your content by allowing quick access to a wide range of emojis.

⚡ Performance improvements: Part 4

Here comes the final batch of the planned performance improvements in the editor loading speed area, that we worked on through a couple of past releases.

  • A new caching mechanism in Mapper now handles model-to-view mappings, substantially improving performance for loading and saving data.
  • Images with specified height and width automatically use [loading="lazy"] in the editing area, optimizing the loading time (read more on MDN). This attribute is only applied during editing to enhance the loading efficiency of images, and it does not reflect in the final data output.

We are greatly satisfied with the improved editor loading times. At the same time, we acknowledge some other problematic areas, and we will keep delivering more performance-related improvements in the future.

MINOR BREAKING CHANGES ℹ️

  • engine: Mapper#registerViewToModelLength() is now deprecated and will be removed in one of the upcoming releases. This method is useful only in obscure and complex converters, where model element, or a group of model elements, are represented very differently in the view. We believe that every feature using a custom view-to-model length callback can be rewritten in a way that this mechanism is no longer necessary. Note: if this method is used, the caching mechanism for Mapper will be turned off which may degrade performance when handling big documents. Note: this method is used by the deprecated legacy lists feature. As a result, you will not experience the performance improvements if you are still using the deprecated legacy lists feature.
  • image: Starting this release, images that have [height] and [width] attributes set will automatically receive the [loading="lazy"] attribute in the editing area. This happens only for the content loaded into the editor, the data output produced by the editor remains the same. The reason for this change is to improve user experience in documents that may contain hundreds of images.
  • list: The lower-alpha and upper-alpha list styles are now upcasted to lower-latin and upper-latin styles.
  • merge-fields: The MergeFieldsEditing#getLabel() method will now return null instead of the merge field id if the merge field definition was not found or it did not contain the label property.
  • basic-styles: Elements which contains the [style] attribute with word-wrap: break-word will not be converted to <code>. See #17789.

Features

  • ai: Comment threads will now be preserved when AI Assistant processes selected content with comments. This can be disabled through the ai.aiAssistant.preserveComments flag. Note, that the actual result depends on the response provided by the AI model (AI model has to keep the comments markup in the response). Additionally, the copy-paste comments functionality must be enabled (configured by comments.copyMarkers).
  • ai: The ai.aiAssistant.removeCommands configuration now allows removing entire command groups.
  • ckbox: It is now allowed to specify which files chosen from CKBox are downloadable. Closes #15928. (commit)
  • clipboard: Added the ability to detect paste events originating from the editor. Closes #15935. (commit)
  • clipboard: Passed information to the downcast converter when clipboard pipeline is used to allow for customization. Closes #17745. (commit)
  • clipboard: The viewToPlainText() helper will now parse the view RawElement instances. Closes #17746. (commit)
  • emoji: Created the Emoji feature. Closes #17361. (commit)
  • image: Added a possibility to break the current block by InsertImageCommand with the breakBlock flag. Closes #17742. (commit)
  • list: Allowed to specify which list style types are shown in list type selector dropdown. Closes #17176. (commit)
  • list: Added support for the lower-alpha and upper-alpha list type highlighting in the list style properties buttons. Closes #17424. (commit)
  • mention: Allowed the mention marker to be longer than 1 character. Closes #17744. (commit)
  • merge-fields: Introduced the image merge fields.
  • merge-fields: Added the [data-merge-field-name] attribute...

v44.1.0

We are pleased to announce the latest CKEditor 5 release, focusing on performance enhancements and key bug fixes to improve your editing and collaboration experience.

Release Highlights

⚡ Performance enhancements: Part 3

This release introduces another set of performance related improvements, focused on faster editor initialization for huge documents. The initialization time was lowered by further 15% to 45%, depending on the tested sample.

The combined improvements introduced in recent releases amount to around 65%-80% lower loading time in total, which means the editor will load 3-5x faster. As the gain is not linear, bigger documents see even better improvement (more than 10x faster).

Moreover, all these improvements positively impact document save time (editor.getData()), which should help with autosave issues, among others.

We still actively work in this area, so you may expect even more editor load and save efficiency improvements in the upcoming releases.

🔨 Bug Fixes and improvements

  • Comments enhancements:
    • Data export options: We introduced the showCommentHighlights option in editor.getData(), that changes the comment marker conversion, allowing for styling comments in the output. Perfect for showing what was commented in Export to PDF, for example.
    • Inline mode improvements: We addressed a problem where comment annotations in inline mode did not close properly when clicking elsewhere in the content.
    • Thread management: We resolved an issue where creating a new thread was not interrupted when the corresponding marker was removed from the content, ensuring better stability during collaborative editing.
  • Revision History update:
    • Restore functionality: We disabled the ability to restore the current (edited, not saved) revision, as it represents current content, so there is nothing to restore. At the same time, using it led to some non-obvious behaviors.
  • Image handling: We resolved an issue where images in the uploading state could be deleted when dragged and dropped within the editor. Keep dragging, even when it is not there 🙈.

🎄 Happy holidays!

As the holiday season approaches, we extend our warmest wishes to our community and users. Thank you for your continued support, and we look forward to bringing you further enhancements and exciting features in the coming year.

MINOR BREAKING CHANGES ℹ️

  • utils: spliceArray now modifies the target array and does not accept a fourth (count) argument.

Features

  • comments: Introduced the showCommentHighlights option in editor.getData() method that changes the comment marker conversion and allows styling the comments in the output.

Bug fixes

  • comments: Resolved an issue where creating a new thread was not interrupted when the corresponding marker was removed from the content, for example, by another user in real-time collaboration.
  • comments: When adding a comment in inline mode, the comment annotation will now close properly if you click elsewhere in the content.
  • find-and-replace: It should be possible to search within content of inline widgets. Closes #11162. (commit)
  • image: Copying and pasting images in the uploading state is now possible. Closes #16967. (commit)
  • ui: Surrounding spaces are no longer added to colors produced by hex inputs. Closes #17386. (commit)

Performance improvements

We have improved how the editor handles the document structure by making it more reliable and efficient to access specific elements and verify their positions.

  • Node index and offset caching: The Node and NodeList elements now cache index and offset values, reducing the need for recalculations and significantly boosting overall performance during model operations.
  • Selection range validation: The newly implemented Position#isValid() method is also utilized to better validate selection ranges, ensuring more consistent behavior in various editing scenarios.
  • Performance improvements in numbers: The editor now loads content between 3x and, in some cases, up to 6x faster, depending on the type and size of the content. For instance, where a specific 200-page document previously took almost 25 seconds to load, the time has now been reduced to just 3.5 seconds.

We’re committed to ongoing performance enhancements, so you can expect even faster, smoother experience in future updates.

Export to Word watermark support

A new configuration option has been added to include a watermark when exporting documents to Word, providing additional flexibility in document branding and protection.

Notable bug fixes and improvements

  • Suggestions retention on revision restore: Suggestions are no longer lost in specific cases when restoring revisions with changes from multiple users. The revision tracking process has been improved to ensure that all operations, including markers, are handled and saved correctly during synchronization. This fix resolves issues where markers were previously not retained, ensuring consistent data handling in collaborative editing scenarios.
  • Action dropdown visibility fix: Resolved an issue where the action dropdown remained hidden after permission changes on comments. The dropdown now properly reflects updated permissions, allowing users to interact with the available actions seamlessly.
  • AI command enhancements:
    • Custom AI Commands are now correctly applied to individual dropdowns when only one group of comments is present, instead of the entire group.
    • Empty comment groups no longer render, improving UI clarity.
    • Fixed an issue where nested AI command menus would close unexpectedly when used within a balloon toolbar, preventing unintended behavior during selection.

Features

  • engine: Introduced the getChildAtOffset() method for model.Element and model.DocumentFragment. (commit)
  • engine: Introduced the Position#isValid() method to check whether the position exists in the current model tree. (commit)
  • export-word: Added a configuration setting for adding a watermark to generated documents.
  • revision-history: Introduced the RevisionTracker#getRevisionDocumentData() and RevisionTracker#getRevisionRootsAttributes() methods to the public scope of the editor API. You can use them to retrieve document data saved with the revision.
  • utils: Made FocusTracker extendable with other FocusTracker instances to allow logical focus tracking across separate DOM sub-trees (see #17277). (commit)

Bug fixes

  • ai: Empty AI Assistant command groups should not render in the UI.
  • ai: The AI Assistant command list should be flat when only one command group is available.
  • comments: Fixed an issue where the action dropdown remained hidden when permissions allowing actions on a comment changed.
  • engine: The content of an inline object should be handled as a flow root so whitespaces should be trimmed as the content of an inline object element is inside a block element. Closes #17199. (commit)
  • image: Handle existing picture element correctly on sources downcast. (commit)
  • link: No longer crash editor after removing link from image when LinkConfig#addTargetToExternalLinks: true is set. Closes #17252. (commit)
  • list-multi-level: Multi-level lists should display correctly in RTL mode for Decoupled Editor.
  • pagination: Improved pagination of large tables that are followed by block elements.
  • revision-history: Suggestions are no longer lost in some scenarios when restoring revisions in real-time collaboration.
  • ui: The dropdown menu component should not cause editor blur if used in a BalloonToolbar while the user hovers a nested menu. Closes #17277. (commit)
  • ui: Made the page unscrollable while the modal is visible. Closes #17093. (commit)

Other changes

  • engine: Node index and offset related values are now cached in model Node and NodeList to improve performance. (commit)
  • link: Exported link and unlink icons from the ckeditor5-link package. Closes #17304. (commit)
  • ui: Disabled dragging support for modal windows in the Dialog plugin. Closes #17290. (commit)

Release highlights

Notable improvements

  • Operational Transformation Stability: Significant changes have been made to the OT system, enhancing the undo functionality and real-time collaboration, especially in conflict resolution scenarios. These improvements ensure smoother editor operations during complex interactions.
  • Performance Improvements: We have merged several community-driven performance enhancements (thanks @sunesimonsen), that optimize the editor’s core engine. While no changes to the editor’s logic were made, these updates improve overall efficiency and responsiveness.

More imports available via ckeditor5 and ckeditor5-premium-features indexes

As users transition to new installation methods (v42.0.0+) with ckeditor5 and ckeditor5-premium-features as the main packages, we are continuously addressing missing imports for less common classes, functions, types, and utilities, broadening their availability. Since our TypeScript rewrite (v37.0.0), imports can now be made directly through the package indexes, simplifying integration. As many users historically imported from src, we encourage you to try the new version and report any missing imports. In the future, we are considering removing src from published packages to reduce package size, so the more feedback we receive, the better and more stable API we will provide.
