- Introduced optimized mmap package and related performance improvements, including optimized bloom filter writes and reduced segment write overhead
- Added new metrics and crash‑tolerant handling (auto‑tenant ops, memtable flushing, vector index tombstones, write metrics) and enhanced shutdown/shard handling
- Fixed multiple issues: memtable flushing crashes, segment load order on recovery, raft lastAppliedIndex updates, BM25 block reading errors, and Google module tests
