Subject: [ANNOUNCE] 3.8.13.14-rt31


Dear RT Folks,

I'm pleased to announce the 3.8.13.14-rt31 stable release.


You can get this release via the git tree at:

  git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git

  branch: v3.8-rt
  Head SHA1: cd0a51313b506fb1837b5877f76a62dbabe3d75e


Or to build 3.8.13.14-rt31 directly, the following patches should be applied:

  http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.8.tar.xz

  http://www.kernel.org/pub/linux/kernel/v3.x/patch-3.8.13.xz

  http://www.kernel.org/pub/linux/kernel/projects/rt/3.8/stable/patch-3.8.13.14.xz

  http://www.kernel.org/pub/linux/kernel/projects/rt/3.8/patch-3.8.13.14-rt31.patch.xz



You can also build from 3.8.13.14-rt30 by applying the incremental patch:

  http://www.kernel.org/pub/linux/kernel/projects/rt/3.8/incr/patch-3.8.13.14-rt30-rt31.patch.xz



Enjoy,

-- Steve
