- Redis 6.0.0 stable includes SSL, ACLs, RESP3, client side caching, threaded I/O, diskless replication, cluster support, and more.
- Client side caching was redesigned: caching slot approach replaced by key names, broadcasting mode added, and opt-in/opt-out support.
- RDB files used for replication can be immediately deleted if no longer useful.
- ACL improvements: new ACL LOG command for debugging, and ACL GENPASS reimplemented using SHA256 HMAC.
- PSYNC2 replication protocol improved for more frequent partial resynchronization.
- Timeout commands now accept decimal numbers and have better resolution.
- RDB loading is 20-30% faster, and INFO command is faster with many clients.
- New STRALGO command implements LCS (longest common subsequence) algorithm.
- Redis 6 is the biggest release ever; users are advised to test carefully before production use.
