- Performance and stability upgrades: configurable compaction intervals, reduced locking in DataCoord, larger metadata batch sizes, WalkWithPrefix for faster etcd ops, and memory reductions by removing unnecessary Bloom filters
- New functional enhancements: RESTful v2 now returns top‑k results, secondary index added to QueryNode segment manager, concurrent collection‑level metadata reads, pprof dump on timeout, and partition limiter skipped when unused
- Extensive bug fixes covering import failures, checkpoint metric leaks, partition load timeouts, index mmap issues, filtered search modulo errors, freeze scenarios during compaction/GC, channel imbalance, flowgraph leaks, and permission/c...
