What's New

v0.52.0 introduces unified Markdown configuration and HeadlessExtension, with breaking changes to selection command timing.

Breaking Changes

SELECTION_CHANGE_COMMAND now runs before DOM reconciliation, affecting automatic notifications.
LexicalNode.getCommonAncestor has been removed.
Default HTML export now honors DOMRenderExtension overrides.

New Features

Unified Markdown configuration using a single MdastExtension.
New HeadlessExtension for building editors entirely from extensions.
Import/export middleware via context.next().

Improvements

Selection notifications now have a consistent timing contract.
Fixes for mobile text input, deletion, horizontal caret scrolling, and drag-and-drop.
Documentation modernization.

Bug Fixes

Fixes for deletion, horizontal caret scrolling, drag-and-drop, and mobile input.

Upgrade Notes

Code relying on LexicalNode.getCommonAncestor must be updated. Selection handlers must now converge to avoid aborting updates. Eligible programmatic changes notify without waiting for native events.
