Hi,

We are happy to announce astng 0.20.0 and pylint 0.20.0 releases.

Pylint http://www.logilab.org/project/pylint is a static code checker based on Astng, both depending on logilab-common 0.49.

Astng http://www.logilab.org/project/logilab-astng builds an enhanced Abstract Syntax Tree for Pylint.

Astng 0.20.0 is a major refactoring and speed improvement, all along fixing a lot of important bugs: http://www.logilab.org/project/logilab-astng/0.20.0

Pylint 0.20.0 uses the new Astng, and fixes a lot of bugs too, adding some new functionalities:

#5564: Parameters with leading "_" shouldn't count as "local" variables #18860: warn on assert( a, b ?) #9776: warning if return or break inside a finally #9982: specific message for NotImplemented exception

For a full list, check http://www.logilab.org/project/pylint/0.20.0
