Redis 3.0.6 和 2.8.24 發布，請盡快更新
Redis 今天發布了兩個更新版本，分別是 3.x 的 3.0.6 以及 2.x 的 2.8.24 版本。
其中 3.0.6 修復了關鍵的 bug，應該立即更新：
Upgrade urgency: MODERATE. We fixed a crash that happens very rarely, so updating does not hurt, but most users are unlikely to experience this condition because it requires some odd timing. However if you are a Redis Cluster user, upgrading is strongly adviced since this release includes very important improvements to Redis Cluster.[FIX] lua_struct.c/getnum security issue fixed. (Luca Bruno discovered it, patched by Sun He and Chris Lamb) [FIX] Redis Cluster replica migration fixed. See issue #2924 for details. (Salvatore Sanfilippo) * [FIX] Fix a race condition in processCommand() because of interactions with freeMemoryIfNeeded(). Details in issue #2948 and especially in the commit message d999f5a. (Race found analytically by Oran Agra, patch by Salvatore Sanfilippo)
[NEW] Backported from the upcoming Redis 3.2: MIGRATE now supports an extended multiple-keys pipelined mode, which is an order of magnitude faster. Redis Cluster now uses this mode in order to perform reshardings and rebalancings. (Salvatore Sanfilippo) [NEW] Backported from the upcoming Redis 3.2: Redis Cluster has now support for rebalancing via the redis-trib rebalance command. Demo here: https://asciinema.org/a/0tw2e5740kouda0yhkqrm5790 Official documentation will be available ASAP. (Salvatore Sanfilippo) [NEW] Redis Cluster redis-trib.rb new "info" subcommand. [NEW] Redis Cluster tests improved. (Salvatore Sanfilippo) * [NEW] Log offending memory access address on SIGSEGV/SIGBUS (Salvatore Sanfilippo)</pre>
2.8.24 也修復了關鍵的 bug，請立即更新：
