* [FIX] Fix software watchdog signal handler crash due to re-entering.
* [FIX] Better Lua number -> string conversion for Lua scripts.
* [FIX] Serious replication bug when min-slaves-* feature is used in slaves
configuration fixed.
* [FIX] Blocking pop on lists now works when the list is created by commands
other than *PUSH* (for example SORT STORE).
>> Cluster changes
* [FIX] CRITICAL: For a bug in the implementation of CLUSTER SET-CONFIG-EPOCH
introduced with beta-3 (especially beta-4 where the command
is actually used by redis-trib), a configEpoch for a node could
jump backward, breaking the eventual consistency property of the
slots -> nodes mapping in the cluster.

--[ Redis 3.0.0 Beta 5 (version 2.9.54) ] Release date: 26 may 2014
This is the 5th beta of Redis 3.0.0. It does not include any real
worthwhile change (just three days passed since the previous beta), but
fixes two stupid bugs preventing cluster tests to pass.
--[ Redis 3.0.0 Beta 4 (version 2.9.53) ] Release date: 23 may 2014
This is the fourth beta of Redis 3.0.0.
>> General changes
* [NEW] Scripting engine performances improvements.
* [NEW] Log format slightly changed to report current node role.
* [FIX] Correct the HyperLogLog stale cache flag to prevent unnecessary
computation.
>> Cluster changes
* [NEW] redis-trib: ability to import data from standalone Redis instances.
* [NEW] redis-trib: "fix" subcommand much better at fixing errors.
* [NEW] CLUSTER FAILOVER FORCE implemented.
* [NEW] CLUSTER RESET implemented, it is now possible to completely reset
nodes and create a new cluster without restarting anything.
* [NEW] Slave validity factor (max estimated data age to still failover)
is now under the control of the user, and can be configured via
redis.conf or CONFIG SET. Option name cluster-slave-validity-factor.
* [NEW] Cluster test: failure detection and failover initial tests.
* [NEW] CLUSTER MEET: better error messages when address is invalid.
* [NEW] Bulk-accept new Cluster nodes in the Cluster bus instead of
performing just a single accept() per event fired.
* [FIX] Bypass data_age check for manual failovers.
* [FIX] Fixed data_age computation / check integer overflow.
* [FIX] Various fixes to Tcl client.tcl Redis Cluster client used in tests.
* [FIX] Better handling of stolen slots.
* [FIX] Don't accept cluster bus connections during startup.
>> Sentinel changes
* [NEW] Generate +config-update-from event when a new config is received.
* [NEW] Log when a failover will be re-attempted again.
* [FIX] Sentinel: Add "dir /tmp" directive in example sentinel.conf.
--[ Redis 3.0.0 Beta 3 (version 2.9.52) ] Release date: 5 may 2014
This is the third beta of Redis 3.0.0.
>> General changes
* [NEW] New data structure: the HyperLogLog (see 2.8 release notes).
* [NEW] Lexicograhical range queries in sorted sets (see 2.8 release notes).
* [NEW] LRU algorithm precision greatly improved.
* [FIX] Redis is now much more responsive to reply with LOADING / BUSY errors.
>> Cluster changes
* [NEW] Cluster testing framework and initial tests.
* [NEW] Cluster epochs collision resolution (make Redis Cluster more resilient
to admin and programming errors).
* [NEW] Persist / fsync some global state to ensure correct crash-recovery
semantics.
* [NEW] New command introduced: CLUSTER SET-CONFIG-EPOCH, still not used
by redis-trib. Will be used to speedup the assignment of unique
epochs to different nodes at cluster creation time. For now this is
handled as a side effect of the cluster epochs collision resolution.
* [FIX] Different fixes to redis-trib cluster creation.
* [FIX] Fix an error in the CLUSTER NODES output for nodes slots.
>> Sentinel changes
* [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.

<ChangeLog>
>> General
* [FIX] Sometimes the absolute config file path was obtained in a wrong way.
This happened when there was a "dir" directive inside the config file
and at the same time the configuration file was given as a relative
path to redis-server or redis-sentinel executables.
* [FIX] redis-cli: Automatically enter --slave mode when SYNC or PSYNC are
called during an interactive session.
* [FIX] BITCOUNT: fixed unaligned access causing issues in sparc and other
archs not capable of dealing with unaligned accesses. This also makes
the code faster in archs where unaligned accesses are allowed.
* [FIX] Force INFO used_memory_peak to match peak memory. This generated some
confusion among users even if it was not an actual bug.
* [FIX] Fixed an critical EVALSHA script cache bug: scripts executed may not
propagate to AOF / Slaves correctly under certain conditions.
See issue #1549 at Github for more information.
* [FIX] Fixed multiple bugs resulting into closing the link with master or slave
during replication without good reasons. This will result in useless
resynchronizations, or infinite loops where the replication link can't
be established.
* [FIX] Don't count the time needed to populate the buffers of clients waiting
in MONITOR mode when populating the Slow Log entries.
* [NEW] Redis-cli updated to use SCAN instead of random sampling via
RANDOMKEY in order to implement --bigkeys feature. Moreover the
implementation now supports pipelining and reports more information
at the end of the scan. Much faster, much better. A special thank
you to Michael Grunder for this improvement.
* [NEW] redis-cli now supports a new --intrinsic-latency mode that is able
to meter the latency of a system due to kernel / hypervisor.
How to use it is explained at http://redis.io/topics/latency.
* [NEW] New command BITPOS: find first bit set or clear in a bitmap.
* [NEW] CONFIG REWRITE calls are now logged.
* [NEW] AOF write errors (like no space on device) no longer abort Redis if the
fsync policy is none or every second. The database enters a read-only
mode where every write is refused with an error. Normal operations are
restored as soon as Redis is able to append again data to the AOF file.
* [NEW] Sentinel now accepts SHUTDOWN command.
>> Cluster
* [FIX] Bind the first interface listed in the "bind" configuration directive
if any, in order to perform outgoing connections. This fixes Cluster
usage when an address is bound but there are multiple interfaces that
may be used to connect with other nodes.
* [FIX] When an "Importing" slot is closed via CLUSTER SETSLOT NODE ...
increment the configEpoch in the special case it is zero.
* [FIX] Current transaction is invalidated on redirection errors.
* [FIX] Abort if port does not allow for a valid cluster bus port that is
always at fixed +10000 offset.
* [FIX] Keys extraction algorithm fixed for ZUNIONSTORE/ZINTERSTORE and SORT.
* [FIX] Better failover timeout and retry times: failover should now work
reliabily when node-timeout is very small (a few milliseconds).
* [FIX] Don't allow SORT GET/BY options in Cluster mode.
* [FIX] Clear importing/migrating state when turning from master to slave role.
* [FIX] Set slot error if we receive an update for a busy slot.
* [FIX] Update node configEpoch on UPDATE messages.
* [NEW] Support multi-key operations as long as keys resolve to the same
hash slot, and the slot is not migrating, or it is migrating but all
the mentioned keys are available.
* [NEW] New DEBUG command CMDKEYS available to debug / test keys identification
in Redis commands.
* [NEW] redis-trib: create subcommand is now able to assign spare slaves.
* [NEW] redis-trib: new subcommand 'call'. Exec command in all nodes.
>> Sentinel
* [FIX] Sentinel "IDONTKNOW" error removed as it does not made sense with the
new Sentinel design. This error was actually a fix for a design error
in the first implementation of Sentinel.
* [FIX] Sentinel: added a missing exit() call to abort after config file
checks at startup. This error was introduced with an improvement in
a previous 2.8 release.
* [FIX] Sentinel: better nodes fail over start time desynchronization to avoid
split-brain during the voting process needed to get authorization to
fail over. This means the system is less likely to need to retry
and will fail over faster. No changes in behavior / correctness.
* [NEW] Sentinel unit tests and framework. More tests needed and units must
be improved in order to have less false positives, but it is a start
and features a debugging console that is useful to fix tests or to
inspect bugs causing tests failures.
* [NEW] New Sentinel events: +/-monitor and +set used to monitor when an
instance to monitor is added or removed, or when a configuration
is modified via SENTINEL SET.

--[ Redis 2.8.5 ] Release date: 4 Feb 2014
# UPGRADE URGENCY: HIGH for Redis, LOW for Sentinel. Redis users using Lua
scripts with expires, and Redis users relying on the
ability of Redis to block writes on RDB saving errors
should plan to upgrade ASAP.
* [FIX] Fixed a replication bug caused by Lua scripts + expired keys: keys could
expire in the middle of scripts causing non-deterministic behavior.
* [FIX] MISCONFIG error if condition fixed, the server was no longer able
to stop writes on RDB misconfiguration after this error was introduced.
* [FIX] REDIS_AOF_REWRITE_MIN_SIZE is now 64mb like example redis.conf default.
* [FIX] Perform fflush() before fsync() in rio.c (bug without actual effects).

* [NEW] Sentinel now has a run time configuration API.
* [NEW] Log when we lost connection with master or slave.

<ChangeLog>
# UPGRADE URGENCY: MODERATE for Redis, HIGH for Sentinel.
* [FIX] Sentinel instance role sampling fixed, the system is now more
reliable during failover and when reconfiguring instances with
non matching configuration.
* [FIX] Inline requests are now handled even when terminated with just LF.
* [FIX] Replication timeout handling greatly improved, now the slave is able
to ping the master while removing the old data from memory, and while
loading the new RDB file. This avoid false timeouts sensed by
masters.
* [FIX] Fixed a replication bug involving 32 bit instances and big datasets
hard to compress that resulted into more than 2GB of RDB file sent.
* [FIX] Return error for inline requests with unbalanced quotes.
* [FIX] Publish the slave replication offset even when disconnected from the
master if there is still a cached master instance.

* [FIX] Fixed a false positive in Redis tests.
</ChangeLog>
<ChangeLog>
# UPGRADE URGENCY: LOW, unless you want to upgrade to new Sentinel code.

UPGRADE URGENCY: HIGH
* [BUGFIX] Theoretical bug in ziplist fixed.
* [BUGFIX] Better out of memory handling (Log produced in log file).
* [BUGFIX] Incrementally flush RDB file on slave side while performing the
first synchronization with the master. This makes Redis less
blocking in environments where disk I/O is slow.
* [BUGFIX] Don't crash with Lua's redis.call() without arguments.
* [BUGFIX] Don't crash after a big number of Lua calls on 32 bit systems
because of a failed assertion.

* [BUGFIX] BITCOUNT: fix crash on overflowing arguments.
* [BUGFIX] Return an error when SELECT argument is not an integer.
* [BUGFIX] Blocking operations on lists were completely reimplemented for
correctness. Now blocking list ops and pushes originated from
Lua scripts will play well together and will be replicated
and transmitted to the AOF correctly.
* [IMPROVED] Send async PING before starting replication to avoid blocking if
master allows us to connect but it is actually not able to reply.
* [IMPROVED] Support slave-priority for Redis Sentinel.
* [IMPROVED] Hiredis library updated.

- Fixed a not critical but important VM bug: from time to time a race
condition may happen and a client may never get the reply from a given
request.
- Now we have a make install target as stated in the README.
- redis-cli no longer tries to understand if it's part of a pipe
so there is to use the -x option to read the last arg from stdin.
This prevents it from creating problem when running inside cron scripts.
- Fixed the init script provided in the tar.gz. It was totally broken.
- Fixed a bug related to connecting more than 10k clients to Redis.

Redis 1.2.6 fixes two critical replication bugs, and a few
improvements.
- Fixed Issue 207 (http://code.google.com/p/redis/issues/detail?id=207)
(broken replication with binary arguments not in the last position
with the MSET command or any other command issued with new
multi-bulk protocol).
- Fixed Issue 174 (http://code.google.com/p/redis/issues/detail?id=174)
(temp names collisions producing broken slave-side .rdb files).
- Redis-cli backported from Redis master, with interactive mode, line
editing via the linenoise library, auth ability, and much more.
- ZRANGEBYSCORE now supports WITHSCORES as well (backported from
master).
- A simplified version of redis-stat (from redis tools) added.
