||||
MODERATE: Program an upgrade of the server, but it's not urgent.

--[ Redis 2.8 Release Candidate 1 (2.7.101) ] Release date: 18 Jul 2013
|
||||
|
||||
This is the first release candidate of Redis 2.8 (official version is 2.7.101).
|
||||
|
||||
The following is a list of improvements in Redis 2.8, compared to Redis 2.6.
|
||||
|
||||
* [NEW] Slaves are now able to partially resynchronize with the master, so most
|
||||
of the times a full resynchornization with the RDB creation in the master
|
||||
side is not needed when the master-slave link is disconnected for a short
|
||||
amount of time.
|
||||
* [NEW] Experimental IPv6 support.4
|
||||
* [NEW] Slaves explicitly ping masters now, a master is able to detect a timedout
|
||||
slave independently.
|
||||
* [NEW] Masters can stop accepting writes if not enough slaves with a given
|
||||
maxium latency are connected.
|
||||
* [NEW] Keyspace changes notifications via Pub/Sub.
|
||||
* [NEW] CONFIG SET maxclients is now available.
|
||||
* [NEW] Ability to bind multiple IP addresses.
|
||||
* [NEW] Set process names so that you can recognize, in the "ps" command output,
|
||||
the listening port of an instance, or if it is a saving child.
|
||||
* [NEW] Automatic memory check on crash.
|
||||
* [NEW] CONFIG REWRITE is able to materialize the changes in the configuration
|
||||
operated using CONFIG SET into the redis.conf file.
|
||||
* [NEW] More NetBSD friendly code base.
|
||||
* [NEW] PUBSUB command for Pub/Sub introspection capabilities.
|
||||
* [NEW] EVALSHA can now be replicated as such, without requiring to be expanded
|
||||
to a full EVAL for the replication link.
|
||||
* [NEW] Better Lua scripts error reporting.
|
||||
* [NEW] SDIFF performances improved.
|
||||
* [FIX] A number of bugfixes.
|
||||
|
||||
Migrating from 2.6 to 2.8
|
||||
=========================
|
||||
|
||||
Redis 2.6 is mostly a strict subset of 2.8. However there are a few things
|
||||
that you should be aware of:
|
||||
|
||||
The following commands changed behavior:
|
||||
|
||||
* SORT with ALPHA now sort according to local collation locale if no STORE
|
||||
option is used.
|
||||
* ZADD/ZINCRBY are now able to accept a bigger range of values as valid
|
||||
scores, that is, all the values you may end having as a result of
|
||||
calling ZINCRBY multiple times.
|
||||
* Many errors are now prefixed by a more specific error code instead of
|
||||
the generic -ERR, for example -WRONGTYPE, -NOAUTH, ...
|
||||
* PUBLISH called inside lua scripts is now correctly propagated to slaves.
|
||||
|
||||
The following redis.conf and CONFIG GET / SET parameters changed:
|
||||
|
||||
* logfile now uses the empty string in order to log to standard output,
|
||||
so 'logfile stdout' is now invalid, use 'logfile ""' instead.
|
||||
|
||||
The following INFO fields changed format in a non-backward compatible way:
|
||||
|
||||
* The list of slaves in INFO is now in field=value format.
|
||||
|
||||
Replication:
|
||||
|
||||
Redis 2.8 can be used as slave for Redis 2.6, but doing this is only
|
||||
a good idea for a short amonut of time needed to upgrade your servers.
|
||||
We suggest to update both master and slaves about at the same time.
