[Pacemaker] Announcing 1.1.12 - Final

[Andrew Beekhof]

I am pleased to report that 1.1.12 is finally done.

This is a really great release and includes three key improvements:  

- ACLs are now on by default
- pacemaker-remote now works for bare-metal nodes
- Thanks to a new algorithm, the CIB is now two orders of magnitude faster. 
  This means less CPU usage by the cluster itself and faster failover times.

I will be building for Fedora shortly, those on other distros (and the impatient) can build their own rpm packages with the instructions below.

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

3. Build Pacemaker

    # make release

4. Copy and deploy as needed


Some stats for this release:

- Changesets: 795
- Diff:       195 files changed, 13772 insertions(+), 6176 deletions(-)
