[jgroups-dev] JGroups 2.10.0.CR1 released

FYI, I released 2.10.0.CR1. There is 1 issue (out of 77) open, and I 
hope to resolve it soon after I return from my trip to the US [1].

The major issues fixed in CR1 are:

    * https://jira.jboss.org/browse/JGRP-1205: tasks could be added to
      the retransmitter (NAKACK) after a channel was closed
    * S3_PING and FILE_PING:
          o https://jira.jboss.org/browse/JGRP-1214: CCME
          o https://jira.jboss.org/browse/JGRP-1217: use UUIDs rather
            than logical names to prevent collisions (different nodes
            using the same name)
          o https://jira.jboss.org/browse/JGRP-1216: removal of failed
            members. Member who were killed by terminating a virtualized
            instance would not get removed from S3 / filesystem,
            therefore creating stale data
          o https://jira.jboss.org/browse/JGRP-1215: at startup, S3_PING
            didn't throw any exceptions when a bucket couldn't be
            created, e.g. because someone else owned it. This will now
            throw an exception with an explanation and prevent the stack
            from starting
          o https://jira.jboss.org/browse/JGRP-1218: underscores are now
            allows in bucket names
          o https://jira.jboss.org/browse/JGRP-1219: use of the 'prefix'
            property to generate a unique bucket name, and prevent
            collisions
    * https://jira.jboss.org/browse/JGRP-1213: GossipRouter now uses
      pinging (if enabled) to remove members which crashed without
      closing their socket into GR. This can happen for example when a
      virtualized instance is terminated
    * Some other GossipRouter changes / improvements / bug fixes

The majority of the fixes / new functionality is related to S3_PING and 
FILE_PING. The motivation is to make it easier for JBossAS to run in an 
EC2 cloud, and offer an alternative to using a GossipRouter (on EC2, IP 
multicasting is not available, to help with discovery).

Enjoy !

P.S.: I hope to see some of you at JBossWorld next week !
