Redis Open Source 8.0.0 release notes.

Redis Open Source 8.0.0 (May 2025)

This is the General Availability release of Redis Open Source 8.0.

Redis 8.0 deprecates previous Redis and Redis Stack versions.

Stand alone RediSearch, RedisJSON, RedisTimeSeries, and RedisBloom modules are no longer needed as they are now part of Redis.

  • (3) Time series.

  • (4-8) Five probabilistic data structures: Bloom filter, Cuckoo filter, Count-min sketch, Top-k, and t-digest.

  • (9) Vector set [preview], a data structure designed for vector similarity search, inspired by sorted set.

  • These nine components are included in all binary distributions.

  • See the build instructions for information about building from source code.

  • New configuration file: redis-full.conf, loads Redis with all components, and contains new configuration parameters for Redis Query Engine and the new data structures .

  • Commands are also included in the existing ACL categories such as @read and @write.

• More than 30 performance and resource utilization improvements.

• A new I/O threading implementation, which enables throughput increase on multi-core environments (set with the io-threads configuration parameter).

• An improved replication mechanism that is more performant and robust.

• New hash commands: HGETDEL, HGETEX, and HSETEX
