--[ Redis 3.0.0 RC6 (version 2.9.106) ] Release date: 24 mar 2015
Upgrade urgency: HIGH because of bugs related to Redis Custer and replication.
This is the 6th release candidate of Redis 3.0.0. This release fixes important
issues discovered during stress testing, and implements safest behavior
for blocking operations during clients reshardings, and a new much needed
functionality of Redis Cluster manual failovers.
In order to fix certain bugs quite a bit of refactoring was needed which
is usually non advisabble in a Release Candidate, but needed in order to
end with a clean fix.
>> General changes
* [FIX] Redis (non clustered & clustered) replication bug involving blocking
operations: see issue #2473. (Salvatore Sanfilippo)
>> Cluster changes
* [FIX] clientsArePaused() fix crashing the old master during manual failover.
(Salvatore Sanfilippo)
* [FIX] Lua scripts replication in Redis Cluster was totally broken.
(Salvatore Sanfilippo)
* [FIX] Redirect clients blocked into list operations when the hash slot
they are blocked into is migrated to another instance or the cluster
state turns into "fail". (Salvatore Sanfilippo)
* [NEW] TAKEOVER option for CLUSTER FAILOVER implemented. It is now possible
to fix a cluster manually in the minority side of the partition, for
example in order to allow for multi DC setups & recovery.
(Salvatore Sanfilippo)
>> Sentinel changes
No changes in Sentinel.
--[ Redis 3.0.0 RC5 (version 2.9.105) ] Release date: 20 mar 2015
Upgrade urgency: Moderate for Redis Cluster users, low otherwise.
This is the 5th release candidate of Redis 3.0.0, released in order to fix
a moderate bug in Redis Cluster. This RC does not shift in the future the
Redis 3.0.0 final release which is scheduled in a few days (we are in the
process of finishing the documentation for Redis Cluster).

* [FIX] More robust slave check in CLUSTER REPLICATE. (Salvatore Sanfilippo)
* [FIX] Fixed possible Redis Cluster node crash due to wrong separation of
concerns between getNodeByQuery() and Cluster global state update
fnuction. (Salvatore Sanfilippo, thx to Ingmar)
* [NEW] Add command CLUSTER MYID to easily featch instance ID. (Michel Martens)
>> Sentinel changes
* [NEW] Support for CLIENT command added. It was missing in the command table.
