Apache Kvrocks is a distributed key value NoSQL database that uses RocksDB as storage engine and is compatible with Redis protocol.
Dependency Updates: RocksDB is bumped from 8.8.1 to 8.11.3 in this version.
Highlights:
Set the default value of redis-cursor-compatible to yes, so from this version, Kvrocks' SCAN will be compatible with Redis by default. We also proudly announce that RESP3 is fully supported now, you can enable the RESP3 feature via set resp3-enabled yes.
In addition, the cluster now can use the rocksdb write-batch to migrate slot data between instances via the APPLYBATCH command, which is faster and consumes less CPU compared to the replay command way.
It is worth mentioning that the community is working on the RedisSearch module, and we look forward to seeing RedisSearch in a future release.

Dependency Updates: RocksDB is bumped from 8.3.3 to 8.8.1 in this version.
Highlights:
We're thrilled to announce that the JSON data structure is supported now, huge thanks to @PragmaTwice and all contributors for making this happen. Also, basic capabilities of Functions have been supported to make up for the lack of modularity of the EVAL-series commands.
From this release, the speedb is allowed to be used as an alternative to rocksdb, you have a try as simple as to append the build option -DENABLE_SPEEDB=ON. Additionally, dynamic change number of worker threads is also supported and users can change it via CONFIG SET workers {NUMBER}. Furthermore, numerous new commands and bug fixes have been implemented.
NOTICE: JSON and BloomFilter is not ready for the cluster mode yet.

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!

Full Changelog: https://github.com/apache/kvrocks/compare/v2.5.1...v2.6.0
Highlights: This release only contains bug fixes since 2.5.0 and some critical issues need to be noticed. For #1615, the data race when reading the cluster slot's info may cause the server to crash in cluster mode, and #1568 / #1593 will also crash the server if users pass the wrong arguments.
Dependency Updates: RocksDB is bumped from 8.1.1 to 8.3.2 in this version.
Highlights: We have supported Redis-compatible SCAN cursors so that you can use any Redis client library to perform the SCAN far painless than before. Enable it via redis-cursor-compatible in the configuration file. Many thanks to @jihuayu. Meanwhile, lots of ZSET commands are newly supported, like ZMPOP, ZRANGESTORE, BZMPOP, ZUNION. Many thanks to @infdahai for driving them and other contributors for implementing them. The detailed changes and contributors are listed below.

Note: In this release, we have upgraded RocksDB to version 8.1.1. In addition, we have introduced a new storage encoding format that can accommodate 64-bit element count and expiration time in milliseconds. To enable this feature, you must include -DENABLE_NEW_ENCODING=ON during the build process (which is not enabled by default). Once the new encoding is enabled, data stored using the old encoding will remain accessible for reading and writing as usual. However, any new data will be written using the new encoding format.

For this release, we now upgrade the RocksDB to 7.9.2 which will significantly improve the compaction performance. Another to be noticed, Kvrocks cluster mode will persist the cluster nodes' topology in the local file by default, you can disable it in flight by config set persist-cluster-nodes-enable no.

For this release, we are still using rocksdb 6.29, but we will update to rocksdb 7 in the next release (as in the unstable branch).
TCL tests are now moved to Go, refer to #811.
ToString() when encoding or decoding the key (#707)level_compaction_dynamic_level_bytes and level base size (#497)Thanks ChrisZMF who implements slot-based data migration for Kvrocks cluster mode, this authentically makes kvrocks cluster scalable. Even though it already is used in production environments, you still should be cautious of it.
Here is a comprehensive list of changes in this release compared to 2.0.5
