ClusterLabs is happy to announce the first release candidate for
Pacemaker version 1.1.15. Source code is available at:

https://github.com/ClusterLabs/pacemaker/releases/tag/Pacemaker-1.1.15-rc1

The most significant enhancements in this release are:

* A new "alerts" section of the CIB allows you to configure scripts that
will be called after significant cluster events. (For details, see the
recent "Coming in 1.1.15: Event-driven alerts" thread on this mailing list.)

* A new pcmk_action_limit option for fence devices allows multiple fence
actions to be executed concurrently. It defaults to 1 to preserve
existing behavior (i.e. serial execution of fence actions).

* Pacemaker Remote support has been improved. Most noticeably, if
pacemaker_remote is stopped without disabling the remote resource first,
any resources will be moved off the node (previously, the node would get
fenced). This allows easier software updates on remote nodes, since
updates often involve restarting the daemon.

* You may notice some files have moved from the pacemaker package to
pacemaker-cli, including most ocf:pacemaker resource agents, the
logrotate configuration, the XML schemas and the SNMP MIB. This allows
Pacemaker Remote nodes to work better when the full pacemaker package is
not installed.

* Have you ever wondered why a resource is not starting when you think
it should? crm_mon will now show why a resource is stopped, for example,
because it is unmanaged, or disabled in the configuration.

* Three significant regressions have been fixed. Compressed CIBs larger
than 1MB are again supported (a regression since 1.1.14), fenced unseen
nodes properly are not marked as unclean (also a regression since
1.1.14), and failures of multiple-level monitor checks should again
cause the resource to fail (a regression since 1.1.10).

As usual, the release includes many bugfixes and minor enhancements. For
a more detailed list of changes, see the change log:

Everyone is encouraged to download, compile and test the new release. We
do many regression tests and simulations, but we can't cover all
possible use cases, so your feedback is important and appreciated.

Many thanks to all contributors of source code to this release,
including Andrew Beekhof, Bin Liu, David Shane Holden, Ferenc Wágner,
Gao Yan, Hideo Yamauchi, Jan Pokorný, Ken Gaillot, Klaus Wenninger,
Kristoffer Grönlund, Lars Ellenberg, Michal Koutný, Nakahira Kazutomo,
Ruben Kerkhof, and Yusuke Iida. Apologies if I have overlooked anyone.
