The binary installer for WinBoard 4.4.4 is now available from the download section of this forum! (Sticky thread in the "WB development and bugfixing" section.)
Note the 4.4.x series is a bugfix-only branch with a feature stop. So for the really advanced stuff you would need a version from the development branch. The most recent version of the development branch is obtainable through a link from that same download section, as a bare executable.
