A release candidate of Redis 2.0.0 is now available.
Redis is a key-value store where the values can be strings, lists, sets, or ordered sets. Data types can be manipulated to push/pop elements, add/remove elements, and perform server side union.
With this release, the list push command now returns the length of the new list, and comes with new tools to check rdb files for unprocessable opcodes, and to check whether AOF is valid. More information is available at the What's New page.
