This new release was planned for a long time. I started working on it at the Pyramid NOLA sprint last February. Since I just finished a project and am looking for new work I had some time to finally finish Lingua 2.
Lingua is a Python package that helps you find translateable texts in your code, and generate POT-file for them. Previous versions handled this as an extractor plugin for Babel. With this release Babel is no longer used and Lingua now has a more powerful extraction framework itself.
