What to do to make a release:
- Have code that builds and works on all ports
- Update README, CHANGELOG and manpage
- Merge code into release branch
- Update version in code (for -v option, in both server and client)
- Export branch into directory
- Run testcases
- Build windows distfile (make cross-mingw-dist), edit version file inside, and rename zipfile to version number
- Clean directory, and tar it
- Upload files to server
