v0.5.0 (2014-04-01)

As a lot of you have already noticed. The sparse 0.5.0 has been tagged and upload to the kernel.org for a while.

One of the most noticeable change of the sparse 0.5.0 is the license. The sparse project has finally move to the MIT license. Thanks for the hard work of Dan Carpenter and Franz Schrober, who contact and collect permissions from the sparse developers. We actually manage to get all developer’s blessing on the MIT license.

This release also has some enhancement matching the latest kernel source annotations. It will reduce the noise level of the sparse warnings.

So there you have it. The official announcement of the sparse 0.5.0.
