Great, works fine here as well.

Cool. I pulled it in, did a changelog, tagged it and now I'm in the
final testing before I push it all out (ETA 30min). I will wait with the
announcement for you to prepare the windows executable from either the
git tag or the release tarball. Docs about building for windows would
be a nice bonus, but for the release I only would like the windows
binary. Please include the version in the filename and also prepare a
.md5 file with the checksum. This way it can go straight to the
release folder with the tarball. Obviously take your time for this.
The final announcement can wait a day or two if you have more
important or better stuff to do. :)
