Upgrade! +CRITICAL: There is a critical bug affecting MOST USERS. Upgrade ASAP. +-------------------------------------------------------------------------------- + +--[ Redis 3.2.0 RC1 (version 3.1.101) ] Release date: 23 dec 2015 + +This is the first release candidate of Redis 3.2. The changelog above shows +what's new in this release. In the next of the following weeks we'll test +in depth every feature and we'll release new RCs as bugs are discovered +and fixed. Note that while 3.2 looks solid already, it contains many changes +to its internals. It's still fresh code compared to 3.0. + +General changes: + +* [NEW] Lua scripts "effect replication". Makes possible to write scripts + with side effects, use of random commands, and so forth. + (Salvatore Sanfilippo) +* [NEW] Geo indexing support via GEOADD, GEORADIUS and other commands. + See http://redis.io/commands/geoadd for more information. + (Initially implemented in a fork of Redis called "Ardb". + Matt Stancliff "imported back" the work to Redis and created the + initial API and implementation. Salvatore Sanfilippo modified + the API and the implementation, fixed bugs, improved performances + and unified the duplicated code with t_zset.c) +* [NEW] Lua debugger. A complete stepping, remote debugger for Lua scripts. + Video here: https://www.youtube.com/watch?v=IMvRfStaoyM +* [NEW] SDS improvements for speed and maximum string length. + This makes Redis more memory efficient in different use cases. + (Design and implementation by Oran Agra, some additional work + by Salvatore Sanfilippo) +* [NEW] Modify Jemalloc size classes to make certain Redis objects fit + better, improving memory efficiency. (Oran Agra) +* [NEW] Better consistency behavior between masters and slaves for expired + keys. The slaves are only able to logically consider a key expired + even before receiving the `DEL` command from the master. This avoids + the delay there is sometimes between the natural expire of the key + and the moment the slave is notified. (Salvatore Sanfilippo) +* [NEW] Support daemon supervision by upstart or systemd (Pierre-Yves Ritschard) +* [NEW] New encoding for the List type: Quicklists. Very important memory + savings and storage space in RDB gains (up to 10x sometimes). + (Design and implementation by Matt Stancliff. RDB storage reworked + by Salvatore Sanfilippo) +* [NEW] SPOP with optional count argument. (Initial implementation by + Alon Diamant, mostly reimplemented by Salvatore Sanfilippo for speed + and in order to make the replication of a this class of commands, + having as logical effect the execution of multiple commands, possible). +* [NEW] Support for RDB AUX fields. Now RDB files contain additional info + like the creation date, version of Redis generating it and so forth. + (Salvatore Sanfilippo) +* [NEW] Faster RDB loading via the RESIZEDB opcode to avoid useless hash tables + rehashings. (Salvatore Sanfilippo) +* [NEW] HSTRLEN command. (@landmime and Salvatore Sanfilippo) +* [NEW] CONFIG SET/GET implementations refactored, partially rewritten, + now exposing more config options. (Salvatore Sanfilippo) +* [NEW] CLUSTER NODES major speedup. (Salvatore Sanfilippo) +* [NEW] CLIENT KILL TYPE MASTER, to kill (disconnect) masters from slaves. + (Salvatore Sanfilippo) +* [NEW] Jemalloc updated to 4.0.3 (Salvatore Sanfilippo) +* [NEW] DEBUG RESTART/CRASH-AND-RECOVER [delay] (Salvatore Sanfilippo) +* [NEW] CLIENT REPLY command implemented: ON, OFF and SKIP modes. + (Salvatore Sanfilippo) +* [NEW] Crash report produced by Redis on crash improved. (Salvatore Sanfilippo) +* [NEW] Better memory test on crash. (Salvatore Sanfilippo) + +Redis Cluster changes: + +* All the Redis Cluster changes in 3.2 were backported to 3.0, so there is + technically nothing new for now in this release. + +Redis Sentinel changes: + +* [NEW] Sentinel connection sharing. Makes Sentinels able to scale to + monitor many masters. (Salvatore Sanfilippo) +* [NEW] New SENTINEL INFO-CACHE command. (Matt Stancliff) +* More things backported to Redis 3.0 in the past, so no longer news of 3.2. + +Migrating from 3.0 to 3.2 +========================= + +Redis 3.0 is mostly a strict subset of 3.2, you should not have any problem +upgrading your application from 3.0 to 3.2. However this is a list of small +non-backward compatible changes introduced in the 3.2 release: + +* The default configuration file now binds to 127.0.0.1. +* Slaves try to no longer expose stale data about already expired keys. +* The RDB format changed. Redis 3.2 is still able to read 3.0 (and all the + past versions) files, but not the other way around. +* Behavior on crash may be different. The crash log format changed and + the memory test executed is now different. + +-------------------------------------------------------------------------------- + +Credits: For each release, a list of changes with the relative author is +provided. Where not specified the implementation and design is done by +Salvatore Sanfilippo. Thanks to Redis Labs for making all this possible. +Also many thanks to all the other contributors and the amazing community +we have. + +Commit messages may contain additional credits. + +Cheers, +Salvatore diff --git a/src/version.h b/src/version.h index dbb6197c82ef69c9dd141b7a6320911b300af7dd..3b8622ac05c07f77af446688ff71be1bc1ff349a 100644 --- a/src/version.h +++ b/src/version.h @@ -1 +1 @@ -#define REDIS_VERSION "3.1.999" +#define REDIS_VERSION "3.1.101"
