一、Redis 3.2 rc 1

　　Redis 3.2 rc 1 正式发布，主要更新如下所示：

　　1. [NEW] Lua scripts "effect replication". Makes possible to write scriptswith side effects, use of random commands, and so forth.(Salvatore Sanfilippo)

　　2. [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)

　　3.[NEW] Lua debugger. A complete stepping, remote debugger for Lua scripts.　Video here: https://www.youtube.com/watch?v=IMvRfStaoyM

　　4.[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)

　　5.[NEW] Modify Jemalloc size classes to make certain Redis objects fit　better, improving memory efficiency. (Oran Agra)

　　6.[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)

　　7.[NEW] Support daemon supervision by upstart or systemd (Pierre-Yves Ritschard)

　　8.[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)

　　9. [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).

　　10.[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)

　　11. [NEW] Faster RDB loading via the RESIZEDB opcode to avoid useless hash tables rehashings. (Salvatore Sanfilippo)

　　12. [NEW] HSTRLEN command. (@landmime and Salvatore Sanfilippo)

　　13.[NEW] CONFIG SET/GET implementations refactored, partially rewritten,now exposing more config options. (Salvatore Sanfilippo)

　　14.[NEW] CLUSTER NODES major speedup. (Salvatore Sanfilippo)

　　15.[NEW] CLIENT KILL TYPE MASTER, to kill (disconnect) masters from slaves.(Salvatore Sanfilippo)

　　16.[NEW] Jemalloc updated to 4.0.3 (Salvatore Sanfilippo)

　　17. [NEW] DEBUG RESTART/CRASH-AND-RECOVER [delay] (Salvatore Sanfilippo)

　　18.[NEW] CLIENT REPLY command implemented: ON, OFF and SKIP modes.(Salvatore Sanfilippo)

　　19. [NEW] Crash report produced by Redis on crash improved. (Salvatore Sanfilippo)

　　20.[NEW] Better memory test on crash. (Salvatore Sanfilippo)
