+Deliver message batches
+-----------------------
+[https://issues.jboss.org/browse/JGRP-2003]
 
-bla
------------------------------------------
-[]
+Receiver (ReceiverAdapter) now has an additional callback receive(MessageBatch batch). This allows JGroups
+to pass an entire batch of messages to the application rather than passing them up one by one.
+
+
+Refactored ENCRYPT into SYM_ENCRYPT and ASYM_ENCRYPT
+----------------------------------------------------
+[https://issues.jboss.org/browse/JGRP-2021]
+
+Plus fixed security issues in the refactored code. Removed ENCRYPT.
+
+
+Measure round-trip times for RPCs via probe
+-------------------------------------------
+[https://issues.jboss.org/browse/JGRP-2049]
+
+Keys 'rpcs' and 'rpcs-details' dump information about average RTTs between individual cluster members
+
+
+Change message bundler at runtime
+---------------------------------
+[https://issues.jboss.org/browse/JGRP-2058]
+
+Message bundlers can be changed at runtime via probe. This is useful to see the effect of different
+bundlers on performance, even in the same test run.

+Reduction of memory size of classes

+Replace Java serialization with JGroups marshalling
+---------------------------------------------------
+[https://issues.jboss.org/browse/JGRP-2033]
+
+Some internal classes still used Java serialization, which opens up security holes
+(google 'java serialization vulnerability').

+Message bundler improvements
+----------------------------
+[https://issues.jboss.org/browse/JGRP-2057]
+
+E.g. removal of SingletonAddress: not needed anymore as shared transports have been removed, too.
+
+
+Protocol: addition of up(Message) and down(Message) callbacks
+-------------------------------------------------------------
+[https://issues.jboss.org/browse/JGRP-2067]
+
+This massively reduces the number of Event creations.
+
+
+TransferQueueBundler: remove multiple messages
+----------------------------------------------
+[https://issues.jboss.org/browse/JGRP-2076]
+
+Instead of removing messages one-by-one, the remover thread now removes as many messages as are in
+the queue (contention) into a local queue (no contention) and then creates and sends message batches off of
+the local queue.
