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.

15 What's new in Redis 2.2.8
16 =========================
17
18 * A new form of dict.c (hash table implementation) iterator that performs less
19 copy-on-write of pages, introduced in Redis 2.2.7, caused ZINTERSTORE,
20 ZUNIONSTORE, SINTER, SINTERSTORE commands to behave in the wrong way.
21 This bug is now fixed.
22 * Print version info before running the test with 'make test'. This is mainly
23 useful for the Continuous Integration system we run.
24 * Fix for DEBUG DIGEST, key may expire on lookup, producing the wrong result.
25 * Replication with expire test modified to produce no or less false failures.
26 * Fixed Z*STORE when dealing with intsets, regression test added.

28 What's new in Redis 2.2.7
29 =========================
30
31 * Fixed bug #543-2 (the issue was reopened with a completely different report)
32 that caused Redis to randomly crash on list push performed against lists
33 with other clients blocked with BLPOP (or variants).
34

35 What's new in Redis 2.2.6
36 =========================
37
38 * Fixed bug #543. If you saw Redis instances crashing on List operations
39 (only happening with a non-default max entry size ziplist setting in
40 redis.conf) it was almost certainly this problem.
41 * Fixed a bug with replication where SLAVEOF NO ONE caused a slave to close the
42 connection with all its slaves.

49 What's new in Redis 2.2.4
50 =========================

54 What's new in Redis 2.2.3
55 =========================
56
57 * Fixed issue #503. MONITOR + QUIT (and other combinations) could crash
58 the server.
59 * OBJECT command implemented. See http://redis.io/commands/object
60 * Fixed a problem in redis-cli related to escapes in the form "\x..".
61 * Fixed a minor memory leak in redis-cli
62 * Saved RDB on SIGTERM on archs where it was not working properly.

64 What's new in Redis 2.2.2
65 =========================
66
67 Redis 2.2.2 is a bugfix release. Changelog:
68
69 * AOF file descriptor leak after the first rewrite fixed.
70 * Return value of GETRANGE / SUBSTR is now an empty string if the interval
71 specified is not valid, or the key does not exist. Was a null bulk reply
72 before, but this is against the Redis way.
73

antirez authored
74 What's new in Redis 2.2.1
75 =========================
76
77 Redis 2.2.1 is a bugfix release. Changelog:
78
79 * Fixed an SPOP crash. When using SPOP in a MULTI/EXEC block there was a problem
80 introduced in the latest release when fixing an SPOP replication/AOF related
81 bug.
82

83 What's new in Redis 2.2.0 final
84 ===============================
85
86 Redis 2.2.0 final is both a bug fix and minor enhancement release:
87
88 * SPOP is now replicated correctly in AOF and across slaves.
89 * CONFIG SET/GET for all the special encoding parameters of sets, lists, hashes.
90 * Now BRPOPLPUSH will reply with single null bulk on timeout.
91 * Specifying port 0 in redis.conf will tell Redis to don't listen on TCP socket.
92 * Propagate key eviction to slaves and AOF, similarly to expires.

94 What's new in Redis 2.1.10 (2.2 Release Candidate 4)
95 ====================================================
96
97 Redis 2.2 RC4 is a bug fix and minor enhancement release:
98
99 * Fixed timeout error in replication where master took a big time to BGSAVE.
100 * Introduced explicit PING between master and slave, to reliably detect when
101 the link is down, even if the socket remains apparently connected.
102 * Fixed compilation on FreeBSD.
103 * Removed a small portability issue in redis-benchmark.

128 What's new in Redis 2.1.9 (2.2 Release Candidate 1)
129 ===================================================

130
131 This is the first Release Candidate of Redis 2.2, in our experience the
132 server is very stable, but in the latest weeks we rewrote part of the internals
133 in order to use a lot less memory while the saving child process is performing
134 a BGREWRITEAOF or a BGSAVE, so handle with care for a couple of weeks.

9fecc40 @antirez release notes, info on 2.0 compatibility
antirez authored
136 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.

138 WHAT'S NEW IN REDIS 2.2 compared to the 2.0 version?
139 ====================================================
4c4dec7 @antirez release notes added
antirez authored
140
141 * Specially encoded data types, small lists and sets can now use up to an order of magnitude less memory.
142 * VM partial rewrite for code cleaness and memory usage.
143 * Change to the implementation of the top level dictionary for better memory efficienty.
144 * redis-cli is hugely improved: tab completion, inline help (Thanks to TJ Holowaychuk), raw output, rewritten using the new hiredis C library.
145 * Networking internals rewritten for efficiency. You can expect LRANGE and similar commands to be at least 10 times faster.
146 * 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.
147 * 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.
148 * Check-and-set (CAS) transactions with the new WATCH command.
149 * Now write operations work against keys with an EXPIRE set! Imagine the possibilities.
150 * 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.

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

152 * Syslog support (Thanks to Jonah H. Harris)
153 * Unix domain socket support.
154 * New List related functions LINSERT, LPUSHX, RPUSHX (Thanks to Robey Pointer)
155 * BRPOPLPUSH (Thanks to Michel Martens and Damian Janowski)
156 * Much more interesting informations in the INFO output.
157 * Sorted sets are now less memory hungry.

158 * Non blocking loading of .rdb / AOF file on startup, with progress information in the INFO output.
