Release Notes: The 'needs_compiler' property was added. File::ShareDir will be automatically added to 'requires' if 'share_dir' is set. The 'build installdeps' action was added to install needed dependencies via a user-configurable command line program (defaults to 'cpan').
Release Notes: A "prereq_data" action was added. There is better interaction with CPANPLUS::Dist::Build. Tests will use File::Temp. There are several other bugfixes.
