The isolated services and experimentalServicesV2 runtime now emit function output at index instead of svc/service-name/index. This is a breaking change to how service functions are deployed and accessed in production environments.

Do this: Update any code or infrastructure that references the old svc/service-name/index path to use the new index path before deploying.

Release notes

Liveblocks v3.20.1

A bug in @liveblocks/client could cause data loss by overwriting room storage with initial values when large WebSocket messages are sent. This is a critical fix for a stable release that users in production must deploy immediately.

Do this: Update to v3.20.1 immediately to prevent data loss from large WebSocket messages overwriting room storage.
