We’re releasing CKEditor 5 v43.3.0 to introduce various performance improvements, add Export to Word watermark support, and fix some minor bugs.

UPDATED Performance improvements

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

  • Node index and offset caching: 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 improve the validation of 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.

In the upcoming months, we’ll continue rolling out a series of performance improvements to ensure an even faster, smoother experience in CKEditor 5.

NEW 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.

Other 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 reflects updated permissions, allowing users to interact seamlessly with the available actions.
  • AI Commands 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.
