[Barrelfish-users] New Barrelfish Release

[Simon Gerber]

Dear all,

We are pleased to announce a new release of the Barrelfish OS. Along
with various bugfixes, this release has improved support for Xeon Phi
(including booting Phi cores using the new coreboot infrastructure) as
well as improvements to our OpenMP runtime.

Additionally, we've adopted Linux's contribution process. If you want to
contribute patches to Barrelfish, add a Signed-off-by: line to the
commit message of your contribution. This certifies that you wrote it or
otherwise have the right to pass your contribution on as an open-source
patch. The detailed rules can be found in our README file [1]

As always, you can get the latest version by cloning or pulling from our
git repository [2].

Cheers,
-- Simon
