Latest version changelog

####25-Dec-2015 - version 2.2.4 released
Please update to this version ASAP due to connection leak discovered in previous versions since Redisson 2.1.4.

Feature - new object added RBlockingDeque
Feature - new object added RSemaphore
Feature - RMapCache.fastPut method with TTL support added
Feature - WeightedRoundRobinBalancer slaves balancer added
Improvement - Memory consumption optimization
Improvement - storing value with ttl = 0 in RSetCache or RMapCache saves it infinitely
Fixed - reconnection handling when Sentinel servers are restarted
Fixed - RedisConnectionException should be throw if Redisson can't connect to servers at startup
Fixed - Connection leak (regression bug since 2.1.4)
Fixed - ConnectionWatchdog throws exception when eventloop in shutdown state
Fixed - RReadWriteLock.forceUnlock works only for current thread
Fixed - MapKeyDecoder and MapValueDecoder are called in wrong order
Fixed - RReadWriteLock doesn't work in cluster mode
