Hello everyone,
on behalf of the Cython project team, I'm proud to announce the final
release of Cython 0.17. This is a major step forward in the development of
the Cython programming language that will make life easier for a lot of
users, rounds up some rough edges of the compiler and adds (preli

Changelog: http://lxml.de/changes-3.0.html
In short, lxml is the most feature-rich and easy-to-use library
