Redis 6 has been made generally available and introduces several significant changes and features, including access control lists (ACLs) that allow for more fine-grained control over user permissions, improved security with SSL encryption, threaded I/O to boost performance, and a new client-side caching layer. The Redis protocol has also evolved with the introduction of RESP3, which offers richer results and paves the way for thinner client libraries. Additionally, Redis 6 includes a cluster proxy to simplify access to Redis clusters in smaller language communities, faster key expiration cycles, and a new command family for finding non-contiguous sequences among strings, known as the longest common subsequence (LCS) commands. These changes aim to make Redis easier to use, more secure, and more performant, opening up vast new possibilities for the Redis community.
