- Breaking change: Docker images are slimmed down for security, removing binaries and packages such as the Temporal CLI, admin tools, curl, jq, and database clients.
- Feature additions: Pre‑release task‑queue fairness with dynamic config, UpdateTaskQueueConfig endpoint for rate‑limiting, eager workflow start enabled by default, and Worker Insights APIs (heartbeat, ListWorkers, DescribeWorker).
- Various bug fixes, versioning improvements, deprecation of old metrics and CLI tools, Nexus and visibility updates, and other stability enhancements.
