Notable features

Full changelog

Add new markdownToCommentBody helper to convert Markdown strings into
CommentBody objects.

room.history.disable(fn) is now officially supported and no longer
experimental. It allows running storage mutations without them appearing on
the undo/redo stacks and it’s intended for background/async writes (e.g.
writing back AI generation results) that should not be undoable.

Fix keyboard shortcut in strikethrough tooltip. (Thanks @HellBoy-OP for the
contribution!)
Fix Yjs undo/redo silently breaking after editor.registerPlugin /
unregisterPlugin is called (e.g. when Tiptap's BubbleMenu, DragHandle,
or SlashCommand mount). The reattach restore() is now installed
unconditionally on view destroy, matching upstream
@tiptap/extension-collaboration. (Thanks @lucasmotta for the contribution!)
