--[ Redis 2.8.8 ] Release date: 25 Mar 2014 # UPGRADE URGENCY: HIGH for Redis, LOW for Sentinel. There is a potentially critical bug fix causing data loss in Redis but it requires a combination of disk full and the use of the SHUTDOWN command. * [FIX] Fixed data loss when SHUTDOWN was used with a disk full condition. * [FIX] Fixed a memory leak in the SORT syntax error processing. * [FIX] When Sentinel down-after-milliseconds parameter is modified at runtime now it gets propagated to all the slaves and sentinel instances of the master. * [FIX] `install_server.sh` script finally fixed. * [FIX] Different fixes to maxclients handling. * [NEW] Sentinels are now able to send update messages in a peer-to-peer fashion even if no Redis instances are available. Now the Sentinel liveness property that the most updated configuration in a given partition is propagated to all the Sentinels is extended to partitions without reachable instances. * [NEW] Sentinel safety properties are now ensured in a crash-recovery system model since some state is persisted on disk before replying to other nodes, and reloaded at startup. * [NEW] Sentinel now uses CLIENT SETNAME so that it is easy to identify Sentinels using CLIENT LIST among other clients. * [NEW] Sentinel failure detection and reconnection code improved. * [NEW] Use all 24 bits (instead of 22) for the Redis objects LRU field. Note that the new LRU algorithm using eviction pools was not backported from unstable for safery / code maturity concerns. * [NEW] Majory speedup for the INFO command (it is now 6 times faster). * [NEW] More Sentinel unit tests. * [NEW] New command DEBUG ERROR returns the specified error. Example: DEBUG ERROR "LOADING database". This is handy to write Redis client libraries unit tests. * [NEW] redis-cli now supports multi-line editing via updated linenoise lib. Thanks to Matt Stancliff and Jan-Erik Rediger for the work done in the context of this release.
