[ClusterLabs] Corosync 3.1.1 is available at corosync.org!

[Jan Friesse]

I am pleased to announce the latest maintenance release of Corosync
3.1.1 available immediately from GitHub release section at 
https://github.com/corosync/corosync/releases or our website at
http://build.clusterlabs.org/corosync/releases/.

This release contains important bug fixes and also a few new features:

  - Added a new API to get extended node/link information which is now 
used by corosync-cfgtool (especially when the new -n parameter is used). 
See corosync-cfgtool(8) for more information.

  - The API for cfg tracking was fixed so it now working again. This API 
was removed during the Corosync 2 development cycle and it means that 
shutdown tracking (using cfg_try_shutdown()) had stopped working.

Now it is back, so an application may register to receive a callback 
when corosync is stopped cleanly (using corosync-cfgtool -H) and can 
also prohibit corosync from stopping.

There is a new --force option (which is now the default in the systemd 
unit file/init script) which will always cause Corosync to shut down.

This feature is going to be used by an as-yet unreleased Pacemaker 
version (currently in the master branch) to veto corosync shutdown.
