Once again, a lot of work has been achieved since the latest 1.1
release. Claudiu, who joined the maintainer team (Torsten and me) did a
great work in the past few months. Also lately Torsten has backported a lot of
things from their internal G[oogle]Pylint. Last but not least, various people contributed by
reporting issues and proposing pull requests. So thanks to everybody!
Notice Pylint 1.2 depends on astroid 1.1 which has been released at the same
time. Currently, code is available on Pypi, and Debian/Ubuntu packages should be ready shortly on Logilab's acceptance repositories.
Below is the changes summary, check the changelog for more info.
New and improved checks:
- New message 'eval-used' checking that the builtin function eval was used.
