Important Notice

This new release introduces significant features, improvements, and fixes.

Dependency Updates: RocksDB version bumps from 8.11.4 to 9.6.1.

Highlights

The new data structure HyperLogLog and its commands are supported now, users can use PF* commands in Kvrocks. Thanks to contributors: @mapleFU @tutububug.

All stream group commands are supported in this release which makes Kvrocks totally compatible with Redis stream.

We allow to enhance the transaction consistency by introducing the db context. It will always use the same snapshot in the transaction while the configuration txn_context_enabled is enabled. Thanks to contributor: @PokIsemaine

Kvrocks Search commands and HNSW index are supported in Kvrocks, but we haven't released them because they're not ready for production at the moment.
