+## [4.0.0] 13th November 2025
+
+Matrix Dart SDK 4.0.0 comes with support for polls, adds first bits towards OIDC and improved
+support for spaces and threads.
+This release also fixes a major performance leak while updating user device keys in the sync loop.
+Especially for larger accounts this should improve the performance a lot.
+v4.0.0 It comes with some breaking changes:
+
+#### Migration guide
+
+- `Client.checkHomeserver()` now returns a fourth value. You can just ignore it if you don't need auth_metadata.
+- `RelationshipType.reply` has been removed in favor of `Event.inReplyToEventId()` where you can set if you want to ignore fallbacks or not. This makes it easier to differenciate fallback replies and replies inside of a thread.
+
