v9.0.0-alpha.0

We are excited to announce the alpha release of the next major version of the React integration.

In this release, we have introduced the following breaking changes that should make using the integration more intuitive and easier.

• ESM-first: Besides the UMD build, the integration is now available in ESM format. In most projects, the new ESM build should be automatically prioritized by bundlers and other tools.
• Support for React 19: We improved support for using the integration in React 19. As a result, the <CKEditorContext> component and the useMultiRootEditor hook should no longer throw errors.

BREAKING CHANGES

• Migrate to ESM. See ckeditor/ckeditor5#16616.

Bug fixes

• Adjusted CKEditorContext format to prevent race conditions in the CKEditor component. (commit)

Other changes

• Added support for React 19. (commit)
