- Fixed a critical bug that could return fewer results than the requested top‑k by excluding L0 segments from readable snapshots.
- Improved performance and usability: removed duplicated schema helper creation, optimized lock handling, avoided double flush of clustering buffer, and added Ubuntu 20.04 compilation support.
- Added new features and documentation: support for dynamic fields in schema helper, msgchannel section in generated YAML, and a clustering compaction user‑guide.
