1 Redis 2.2 release notes
2
3 Migrating from 2.0 to 2.2
4 =========================
5
6 Redis 2.0 is mostly a strict subset of 2.2. Some return value changed in edge
7 cases, basicaly it is very unlikely that you will experience any problem
8 upgrading your 2.0 instances to 2.2, as 2.2 can work as a drop in replacement
9 for 2.0.

20 What's new in Redis 2.2.3
21 =========================
22
23 * Fixed issue #503. MONITOR + QUIT (and other combinations) could crash
24 the server.
25 * OBJECT command implemented. See http://redis.io/commands/object
26 * Fixed a problem in redis-cli related to escapes in the form "\x..".
27 * Fixed a minor memory leak in redis-cli
28 * Saved RDB on SIGTERM on archs where it was not working properly.

30 What's new in Redis 2.2.2
31 =========================
32
33 Redis 2.2.2 is a bugfix release. Changelog:
34
35 * AOF file descriptor leak after the first rewrite fixed.
36 * Return value of GETRANGE / SUBSTR is now an empty string if the interval
37 specified is not valid, or the key does not exist. Was a null bulk reply
38 before, but this is against the Redis way.

40 What's new in Redis 2.2.1
41 =========================
42
43 Redis 2.2.1 is a bugfix release. Changelog:
44

46 introduced in the latest release when fixing an SPOP replication/AOF related
47 bug.

49 What's new in Redis 2.2.0 final
50 ===============================
51
52 Redis 2.2.0 final is both a bug fix and minor enhancement release:
53
54 * SPOP is now replicated correctly in AOF and across slaves.
55 * CONFIG SET/GET for all the special encoding parameters of sets, lists, hashes.
56 * Now BRPOPLPUSH will reply with single null bulk on timeout.
57 * Specifying port 0 in redis.conf will tell Redis to don't listen on TCP socket.
58 * Propagate key eviction to slaves and AOF, similarly to expires.

60 What's new in Redis 2.1.10 (2.2 Release Candidate 4)
61 ====================================================
62
63 Redis 2.2 RC4 is a bug fix and minor enhancement release:
64
65 * Fixed timeout error in replication where master took a big time to BGSAVE.
66 * Introduced explicit PING between master and slave, to reliably detect when
67 the link is down, even if the socket remains apparently connected.
68 * Fixed compilation on FreeBSD.
69 * Removed a small portability issue in redis-benchmark.

97 This is the first Release Candidate of Redis 2.2, in our experience the
98 server is very stable, but in the latest weeks we rewrote part of the internals
99 in order to use a lot less memory while the saving child process is performing
100 a BGREWRITEAOF or a BGSAVE, so handle with care for a couple of weeks.

authored
102 Oh, and I've some very good news: the majority of apps can work if you simply replace 2.2 in your old 2.0 environment. I can't think of any breakage.

104 WHAT'S NEW IN REDIS 2.2 compared to the 2.0 version?
105 ====================================================
4c4dec7 @antirez release notes added

106
107 * Specially encoded data types, small lists and sets can now use up to an order of magnitude less memory.
108 * VM partial rewrite for code cleaness and memory usage.
109 * Change to the implementation of the top level dictionary for better memory efficienty.
110 * redis-cli is hugely improved: tab completion, inline help (Thanks to TJ Holowaychuk), raw output, rewritten using the new hiredis C library.
111 * Networking internals rewritten for efficiency. You can expect LRANGE and similar commands to be at least 10 times faster.
112 * Most read only commands are now copy-on-write friendly, this means that Redis will use little memory when a saving child is active and the parent process is mostly stressed by read queries.
113 * Non blocking replication even from the point of view of the slave, with configurable behavior about what to do when the link is disconnected. You can select if serving old data or replying with an error.
114 * Check-and-set (CAS) transactions with the new WATCH command.
115 * Now write operations work against keys with an EXPIRE set! Imagine the possibilities.
116 * New maxmemory eviction policies. It is possible to select among LRU, farest TTL expire, and other algorithms, and if when the memory limit is reached only keys with an expire set or all the keys should be expired.

117 * SETBIT / GETBIT / SETRANGE / GETRANGE / STRLEN. Now your strings are your arrays!

118 * Syslog support (Thanks to Jonah H. Harris)
119 * Unix domain socket support.
120 * New List related functions LINSERT, LPUSHX, RPUSHX (Thanks to Robey Pointer)
121 * BRPOPLPUSH (Thanks to Michel Martens and Damian Janowski)
122 * Much more interesting informations in the INFO output.
123 * Sorted sets are now less memory hungry.
