[Pacemaker] Announcing Pacemaker v1.1.11

Thu Feb 13 17:26:39 UTC 2014

I am excited to announce the release of Pacemaker v1.1.11

  https://github.com/ClusterLabs/pacemaker/releases/tag/Pacemaker-1.1.11

There were no changes between the final release and rc5.

This has been a very successful release process.  I'm proud of the testing
and contributions the community put into this release.  Thank you all for
your support, this community is great :D

Looking forward to Pacemaker 1.1.12, we have a lot of new functionality on
the horizon. Scaling pacemaker from a dozen or so nodes to hundreds possibly
thousands of nodes is a very real and attainable goal for us this year.  An
announcement about 1.1.12 features and beta testing should arrive in the next
few months.

If you are a user of `pacemaker_remoted`, you should take the time to read

To build `rpm` packages:

1. Clone the current sources:

       # git clone --depth 0 git://github.com/ClusterLabs/pacemaker.git
       # cd pacemaker

2. Install dependancies (if you haven't already)

       [Fedora] # sudo yum install -y yum-utils
       [ALL]        # make rpm-dep
