New features　　============
　　
　　Probe improvements
　　------------------
　　[https://issues.jboss.org/browse/JGRP-2004]
　　[https://issues.jboss.org/browse/JGRP-2005]
　　
　　- Proper discarding of messages from a different cluster with '-cluster' option.
　　- Less information per cluster member; only the requested information is returned
　　- Detailed information about RPCs (number of sync, async RPCs, plus timings)
　　- http://www.jgroups.org/manual/index.html#_looking_at_details_of_rpcs_with_probe
　　
　　
　　
　　Optimizations
　　=============
　　
　　DONT_BUNDLE and OOB: messages are not removed from batch when execution fails
　　-----------------------------------------------------------------------------
　　[https://issues.jboss.org/browse/JGRP-2015]
　　
　　- Messages are not removed from batch when execution fails
　　- Rejections are not counted to num_rejected_msgs
　　
　　
　　COMPRESS: removed 1 byte[] buff copy
　　------------------------------------
　　[https://issues.jboss.org/browse/JGRP-2017]
　　
　　An unneeded copy of the compressed payload was created when sending and compressing a message. The fix should reduce
　　memory allocation pressure quite a bit.
　　
　　
　　RpcDispatcher: don't copy the first anycast
　　-------------------------------------------
　　[https://issues.jboss.org/browse/JGRP-2010]
　　
　　When sending an anycast to 3 destinations, JGroups sends a copy of the original message to all 3. However, the first
　　doesn't need to be copied (less memory allocation pressure). For an anycast to a single destination, no copy is
　　needed, either.
　　
　　

　　Compaction of in-memory>　　----------------------------
　　[https://issues.jboss.org/browse/JGRP-2011]
　　[https://issues.jboss.org/browse/JGRP-2012]
　　
　　- Reduced> 24 bytes

　　- Request/UnicastRequest/GroupRequest: reduced>　　
　　
　　RequestCorrelator.done() is slow
　　--------------------------------
　　[https://issues.jboss.org/browse/JGRP-2013]
　　
　　Used by RpcDispatcher. Fixed by eliminating the linear search done previously.
　　
　　
　　
　　Bug fixes
　　=========
　　
　　FILE_PING: consider special characters in file names
　　----------------------------------------------------
　　[https://issues.jboss.org/browse/JGRP-2014]
　　
　　Names like "A/web-cluster" would fail on Windows as the slash char ('/') was treated as demarcation char in some clouds.
