- Added bulk insertion from files, query pagination, collection‑level TTL, quota limits, RBAC, DiskANN (beta) and data backup features.
- Refactored coordinators and etcd storage (query coord V2, root/index coord, compression) with performance improvements, full CPU utilization, and faster load/search.
- Introduced breaking changes: incompatibility with prior versions, new index‑load constraints, disabled Time Travel by default, and altered flush API behavior.
