+### Peer-to-peer synchronisation
+
+#### Improved
+
+- An optional self-hosted Coturn Compose starter is now available for P2P deployments that need a TURN relay. It uses a pinned upstream image and documents its network, credential, security, and verification boundaries.
+    - The message-size and connection-path controls remain a separate implementation.
+    - Thank you to @andrewschreiber for the detailed fragmentation diagnosis and working 800-byte threshold in vrtmrz/livesync-commonlib#97, which informed this compatibility design.
