Subject: Linux 3.12.30
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I'm announcing the release of the 3.12.30 kernel.
All users of the 3.12 kernel series may upgrade.
This is more or less a performance release.
It was possible only thanks to help from Mel.
The updated 3.12.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
linux-3.12.y
and can be browsed at the normal kernel.org git web browser:
