-Redis 2.6 release notes
+Redis 2.7 release notes
 =======================
 
-** IMPORTANT ** Check the 'Migrating from 2.4 to 2.6' section at the end of
-                this file for information about what changed between 2.4 and
-                2.6 and how this may affect your application.
+This is the unstable version of Redis 2.8, currently work in progress.
 
---------------------------------------------------------------------------------
-Upgrade urgency levels:
+When it will be ready it will be releaed as Redis 2.8.0
 
-LOW:      No need to upgrade unless there are new features you want to use.
-MODERATE: Program an upgrade of the server, but it's not urgent.
-HIGH:     There is a critical bug that may affect a subset of users. Upgrade!
-CRITICAL: There is a critical bug affecting MOST USERS. Upgrade ASAP.
---------------------------------------------------------------------------------
-
----[ Redis 2.6.0 ]
-
-* [BUGFIX]   Allow AUTH when server is in -BUSY state because of a slow script.
-* [BUGFIX]   MULTI/EXEC flow now makes sense when observed in MONITOR
-* [BUGFIX]   SCRIPT KILL now uses different error prefixes for different errors.
-* [BUGFIX]   Default memory limit for 32bit archs lowered from 3.5 to 3 GB.
-* [BUGFIX]   redis-check-dump is now compatible with RDB files generated by 2.6.
-* [IMPROVED] New field in INFO: slave_read_only.
-
----[ Redis 2.5.14 (2.6 Release Candidate 8) ]
-
-* [BUGFIX]   Fixed compilation on FreeBSD.
-* [IMPROVED] SRANDMEMBER <count> that returns multiple random elements.
-* [IMPROVED] Sentinel backported to 2.6. It will be taken in sync with 2.8.
-* [IMPROVED] Helper function for scripting to return errors and status replies.
-* [IMPROVED] SORT by nosort [ASC|DESC] uses sorted set elements ordering.
-* [BUGFIX]   Better resistence to system clock skew.
-* [IMPROVED] Warn the user when the configured maxmemory seems odd.
-* [BUGFIX]   Hashing function is now murmurhash2 for security purposes.
-* [IMPROVED] Install script no longer uses a template but redis.conf itself.
-
----[ Redis 2.5.13 (2.6 Release Candidate 7) ]
-
-UPGRADE URGENCY: HIGH
-
-* [BUGFIX]   Theoretical bug in ziplist fixed.
-* [BUGFIX]   Better out of memory handling (Log produced in log file).
-* [BUGFIX]   Incrementally flush RDB file on slave side while performing the
-             first synchronization with the master. This makes Redis less
-             blocking in environments where disk I/O is slow.
-* [BUGFIX]   Don't crash with Lua's redis.call() without arguments.
-* [BUGFIX]   Don't crash after a big number of Lua calls on 32 bit systems
-             because of a failed assertion.
-* [BUGFIX]   Fix SORT behaviour when called from scripting.
-* [BUGFIX]   Adjust slave PING period accordingly to REDIS_HZ define.
-* [BUGFIX]   BITCOUNT: fix crash on overflowing arguments.
-* [BUGFIX]   Return an error when SELECT argument is not an integer.
-* [BUGFIX]   Blocking operations on lists were completely reimplemented for
-             correctness. Now blocking list ops and pushes originated from
-             Lua scripts will play well together and will be replicated
-             and transmitted to the AOF correctly.
-* [IMPROVED] Send async PING before starting replication to avoid blocking if
-             master allows us to connect but it is actually not able to reply.
-* [IMPROVED] Support slave-priority for Redis Sentinel.
-* [IMPROVED] Hiredis library updated.
-
----[ Redis 2.5.12 (2.6 Release Candidate 6) ]
-
-UPGRADE URGENCY: MODERATE.
-
-* [BUGFIX]   Fixed a timing attack on AUTH (Issue #560).
-* [BUGFIX]   Don't assume that "char" is signed.
-* [BUGFIX]   Check that we have connection before enabling pipe mode.
-* [BUGFIX]   Use the optimized version of the function to convert a double to
-             its string representation. Compilation was disabled because of
-             a typo in the #if statement.
-* [IMPROVED} REPLCONF internal command introduced, now INFO shows slaves with
-             correct port numbers. This makes 2.5.12 Redis Sentinel compatible.
-* [IMPROVED] Truncate short write from the AOF for a cleaner restart. On short
-             writes (for instance out of space) Redis will now try to remove
-             the half-written data so that the next restart will work without
-             the need for the "redis-check-aof" utility.
-* [IMPROVED] New in INFO: aof_last_bgrewrite_status
-* [IMPROVED] Allow Pub/Sub in contexts where other commands are blocked.
-* [BUGFIX]   mark fd as writable when EPOLLERR or EPOLLHUP is returned by
-             epoll_wait.
-
----[ Redis 2.5.11 (2.6 Release Candidate 5) ]
-
-UPGRADE URGENCY: HIGH.
-
-* [BUGFIX]   Fixed Hash corruption when loading an RDB file generated by
-             previous versions of Redis that encoded hashes using
-             a different ziplist encoding format for small integers.
-             All the fileds that are integers in the range 0-255 may not
-             be recognized, or duplicated un updates, causing a crash
-             when the ziplist is converted to a real hash. (Issue #547).
-* [BUGFIX]   Fixed the count of memory used by output buffers in the
-             setDeferredMultiBulkLength() function.
-
----[ Redis 2.5.10 (2.6 Release Candidate 4) ]
-
-UPGRADE URGENCY: HIGH.
-
-* [BUGFIX]   Allow PREFIX to be overwritten on "make install".
-* [BUGFIX]   Run the test with just one client if the computer is slow.
-* [BUGFIX]   Event port support in our event driven libray.
-* [BUGFIX]   Jemalloc updated to 3.0.0. This fixes a possibly AOF rewrite issue.
-             See https://github.com/antirez/redis/issues/504 for info.
-* [BUGFIX]   Fixed issue #516: ZINTERSTORE / ZUNIONSTORE with mixed sets/zsets.
-* [BUGFIX]   Set fd to writable when poll(2) detects POLLERR or POLLHUP event.
-* [BUGFIX]   Fixed RESTORE hash failure (Issue #532).
-* [IMPROVED] Allow an AOF rewrite buffer > 2GB (Related to issue #504).
-* [IMPROVED] Server cron function frequency is now configurable (REDIS_HZ).
-* [IMPROVED] Better, less blocking expired keys collection algorithm.
-* [FEATURE]  New commands: BITOP and BITCOUNT.
-* [FEATURE]  redis-cli --pipe for mass import.
-
-What's new in Redis 2.5.9 (aka 2.6 Release Candidate 3)
-=======================================================
-
-UPGRADE URGENCY: critical, upgrade ASAP.
-
-* [BUGFIX] Fix for issue #500 (https://github.com/antirez/redis/pull/500).
-           Redis 2.6-RC1 and RC2 may corrupt ziplist-encoded sorted sets
-           produced by Redis 2.4.x.
-* [BUGFIX] Fixed several bugs in init.d script.
-* [BUGFIX] syncio.c functions modified for speed and correctness. On osx
-           (and possibly other BSD-based systems) the slave would block on
-           replication to send the SYNC command when the master was not
-           available. This is fixed now, but was not affecting Linux installs.
-* Now when slave-serve-stale-data is set to yes and the master is down, instead
-  of reporting a generic error Redis replies with -MASTERDOWN.
-
-What's new in Redis 2.5.8 (aka 2.6 Release Candidate 2)
-=======================================================
-
-UPGRADE URGENCY: high for all the users of the KEYS command, otherwise low.
-
-* [BUGFIX] Fix for KEYS command: if the DB contains keys with expires the KEYS
-           command may return the wrong output, having duplicated or missing
-           keys. See issue #487 and #488 on github for details.
-
-What's new in Redis 2.5.7 (aka 2.6 Release Candidate 1)
-=======================================================
-
-UPGRADE URGENCY: upgrade not recommended because this is an RC release.
-
-* This is the first release candidate for Redis 2.6. We are not aware of
-  bugs, but part of this code is young and was never tested in production
-  environments, so handle with care.
-
-An overview of new features and changes in Redis 2.6.x
-======================================================
-
-* Server side Lua scripting, see http://redis.io/commands/eval
-* Virtual Memory removed (was deprecated in 2.4)
-* Hardcoded limits about max number of clients removed.
-* AOF low level semantics is generally more sane, and especially when used
-  in slaves.
-* Milliseconds resolution expires, also added new commands with milliseconds
-  precision (PEXPIRE, PTTL, ...).
-* Better memory usage for "small" lists, ziplists and hashes when fields or
-  values contain small integers.
-* Read only slaves.
-* New bit opeations: BITCOUNT and BITOP commands.
-* Clients max output buffer soft and hard limits. You can specifiy different
-  limits for different classes of clients (normal,pubsub,slave).
-* More incremental (less blocking) expired keys collection algorithm, in
-  practical terms this means that Redis is more responsive when a very
-  big number of keys expire about at the same time.
-* AOF is now able to rewrite aggregate data types using variadic commands,
-  often producing an AOF that is faster to save, load, and is smaller in size.
-* Every redis.conf directive is now accepted as a command line option for the
-  redis-server binary, with the same name and number of arguments.
-* Hash table seed randomization for protection against collisions attacks.
-* Performances improved when writing large objects to Redis.
-* Integrated memory test, see redis-server --test-memory.
-* INCRBYFLOAT and HINCRBYFLOAT commands.
-* New DUMP, RESTORE, MIGRATE commands (back ported from Redis Cluster to 2.6).
-* CRC64 checksump in RDB files.
-* Better MONITOR output and behavior (now commands are logged before execution).
-* "Software Watchdog" feature to debug latency issues.
-* Significant parts of the core refactored or rewritten. New internal APIs
-  and core changes allowed to develop Redis Cluster on top of the new code,
-  however for 2.6 all the cluster code was removed, and will be released with
-  Redis 3.0 when it is more complete and stable.
-* Redis ASCII art logo added at startup.
-* Crash report on memory violation or failed asserts improved significantly
-  to make debugging of hard to catch bugs simpler.
-* redis-benchmark improvements: ability to run selected tests,
-  CSV output, faster, better help.
-* redis-cli improvements: --eval for comfortable development of Lua scripts.
-* SHUTDOWN now supports two optional arguments: "SAVE" and "NOSAVE".
-* INFO output split into sections, the command is now able to just show 
-  pecific sections.
-* New statistics about how many time a command was called, and how much
-  execution time it used (INFO commandstats).
-* More predictable SORT behavior in edge cases.
-* Better support for big endian and *BSD systems.
-* Build system improved.
-
-Migrating from 2.4 to 2.6
-=========================
-
-Redis 2.4 is mostly a strict subset of 2.6. However there are a few things
-that you should be aware of:
-
-* You can't use .rdb and AOF files generated with 2.6 into a 2.4 instance.
-* 2.6 slaves can be attached to 2.4 masters, but not the contrary, and only
-  for the time needed to perform the version upgrade.
-
-There are also a few API differences, that are unlikely to cause problems,
-but it is better to keep them in mind:
-
-* SORT now will refuse to sort in numerical mode elements that can't be parsed
-  as numbers.
-* EXPIREs now all have millisecond resolution (but this is very unlikely to
-  break code that was not conceived exploting the previous resolution error
-  in some way.)
-* INFO output is a bit different now, and contains empty lines and comments
-  starting with '#'. All the major clients should be already fixed to work
-  with the new INFO format.
-* Slaves are only read-only by default (but you can change this easily
-  setting the "slave-read-only" configuration option to "no" editing your
-  redis.conf or using CONFIG SET.
-
-The following INFO fields were renamed for consistency:
-
-     changes_since_last_save -> rdb_changes_since_last_save
-     bgsave_in_progress -> rdb_bgsave_in_progress
-     last_save_time -> rdb_last_save_time
-     last_bgsave_status -> rdb_last_bgsave_status
-     bgrewriteaof_in_progress -> aof_rewrite_in_progress
-     bgrewriteaof_scheduled -> aof_rewrite_scheduled
-
-The following redis.conf and CONFIG GET / SET parameters changed:
-
-    * hash-max-zipmap-entries, now replaced by hash-max-ziplist-entries
-    * hash-max-zipmap-value, now replaced by hash-max-ziplist-value
-    * glueoutputbuf option was now completely removed (was deprecated)
