Redis 2.8 hit release candidate 2 status this week with some of the major bugs finally getting fixed. The new release should be a welcome change given Redis' recent, and very public, incident with Twilio's billing system.
Here's what's new in 2.8:
Redis 2.8 is almost ready to replace 2.6, providing significant improvements like: Replication partial resynchronization, IPv6 support, config rewriting, keyspace changes notifications via Pub/Sub, and more. While it is not production ready, it is considered beta-quality code with a good degree of stability. See the Release Notes for a full list of changes.
I couldn't confirm a GA release date but you should probably start getting your system ready if you use Redis and plan to upgrade. If you've looked at Redis before, you might want to look again given these new features.
Here's a post by the creator of Redis about some of the new features.
