A little more than a week later, Tenacity 1.3 beta 2 is already out. This is a hotfix release that fixes MP3 exports on Windows requiring LAME to be loaded. On a side note, a little activity from Weblate came in, so you might see one or two translations very slightly modified in some way.
FFmpeg libraries are also provided here as well like in beta 1, but these are the exact same libraries as the ones presented alongside 1.3 beta 1. They are provided here for convenience.
