[Barrelfish-users] [Barrelfish] New Barrelfish Release

[David Cock]

Dear all,

We are pleased to announce a new release of the Barrelfish OS. This 
release includes large page support on ARM, and a significant overhaul 
of the build system.  Runtime and memory consumption of Hake have 
dropped by a factor of 10 and 20, respectively.  The new build system 
also introduces the concept of 'build platforms' - top-level targets for 
each platform (e.g. x86_64 or PandaboardES).  Almost all Makefile 
targets are now generated by Hake - very little remains in 
symbolic_targets.mk.

Support for Intel SCC and for ARM11MP (ARMv6) has been dropped in this 
release, as we no longer maintain the corresponding hardware.  Code for 
these platforms will continue to be available via previous release tags 
in the repository.

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

Cheers,
-- David
