2.6.0

Important Notice

Dependency Updates: RocksDB is bumped from 8.3.2 to 8.3.3 in this version.

Configuration Changes: The default value of max-io-mb is changed to 0 (unlimited), and rocksdb.level_compaction_dynamic_level_bytes changed to yes from no.

Highlights: In this release, we have added support for the BloomFilter data structure and most of its commands (prefixed with BF.). Special thanks to @zncleon and @mapleFU. Additionally, the RESTORE command has been supported by @git-hulk to facilitate various data migration scenarios, such as using RedisShake upon Kvrocks. Moreover, TLS can now secure not only server connections but also replication connections. Furthermore, numerous new commands and bug fixes have been implemented. We extend our gratitude to all contributors!
