Release highlights

We are happy to announce the release of CKEditor 5 v35.0.0 that contains a security fix for the Markdown GFM, HTML support and HTML embed packages.

MAJOR BREAKING CHANGES ℹ️

• The source element is not updated automatically after the editor destroy.

MINOR BREAKING CHANGES ℹ️

• engine: The DomConverter#viewToDom() and DomConverter#viewChildrenToDom() parameter lists have changed (the 2nd parameter – the DOM document instance is no longer accepted).
• image: The ImageInsertPanelView#dropdownView property is no longer accessible. Use editor.plugins.get( 'ImageInsertUI' ).dropdownView instead to access the image insert dropdown instance. See #11654.
• ui: Before, preventDefault() was called on the mousedown event to prevent the ButtonView class from "stealing" the focus from the editing root. Starting this release, to improve the accessibility of the editor, all instances of the ButtonView class (and its child classes) will automatically focus in DOM when clicked. It is recommended for features using buttons to manage the content to call editor.editing.view.focus() after the button was executed in order to bring the DOM focus back to the editing root to allow users type right away.
