I've finally taken the time to take care of the corosync and pacemaker ebuilds. The new versions are now available in portage.
Corosync 1.4.3 (10/04/2012)¶
This is one of the last supported old stable release of the Corosync Cluster Engine. FYI, I've also bumped the new corosync-2.0.0 version but it needs more testing before I hard-unmask it.
Pacemaker 1.1.7 (28/03/12)¶
This is a bug fix release of Pacemaker. See the changelog for details.
Special thanks to my fellow Gentoo Linux developer Kacper Kowalik (xarthisius) for his help on these bumps.
