The 1.1.2-2 release contains the following changes:

Overview

Kernel version:

- Removed a cpu usage kernel patch that was causing kernel panics.

Apache mod_betterlinux:

Added support for Apache 2.4.x

Minor changes, including making licensing information visable from the "General" tab.

-Resolved the reported cpud segfault libpthread-2.12.so error
-Performance improvements

Upgrading BetterLinux:

To upgrade BetterLinux 1.1.2-2 on a CentOS 6.4 or 6.3 server, you must manually change the betterlinux.repo and betterlinux-cpanel.repo files in /etc/yum.repo.d. Change the baseurl line "$releaseever" references to either "6.4" or "6.3" and save the files.

Example change:

Before the change:

baseurl=http://repo.betterlinux.com/1.0/centos/$releasever/$basearch/Packages/

After the change:

baseurl=http://repo.betterlinux.com/1.0/centos/6.4/$basearch/Packages/


Then run this:

    yum --disableexcludes=all upgrade betterlinux\*

If you plan to upgrade to CentOS 6.5, do the CentOS upgrade first; no repo file changes are required, just run the yum upgrade command like this:

    yum --disableexcludes=all upgrade betterlinux\*

Then reboot your system.
