- Added support for sparse vectors (SPLADE/BM25), discovery search, user‑defined sharding, shard snapshot transfer, Manhattan distance metric, and read‑only API keys (security).
- Implemented wide performance and stability improvements (HNSW build, geo payload indexing, consensus reliability, search latency, group‑by efficiency, health checks, WAL checksum, cleanup of snapshots/RocksDB), plus UI enhancements like ...
- Fixed many bugs across vector storage, consensus syncing, TLS handling, snapshot creation, and client response codes; introduced deprecation marking point/vector/index counts as approximate.
