- Introduced major features: batch update endpoint, binary quantization, shard snapshot API, indexed_only search flag, gRPC reflection, Kubernetes health probes, stack trace API and optimizer telemetry.
- Improved reliability and observability: automatic shard load recovery, enhanced logging, RAM optimizations, Docker OCI labels, and cleanup of temporary directories.
- Fixed numerous stability issues and a critical Rustls PKI vulnerability, addressing crashes, raft state corruption, optimizer panics, and incorrect ID recovery.
