WinFF 1.5.5 is mostly just a cleaned up and repacked winff 1.5.4 for possibly the final version.
For now (and maybe ever), I am going to be hosting winff on my personal site.
This maybe the final version of WinFF except for preset updates. The WinFF website is being retired after 10 years. Thanks to Paul Gevers, Ian Stoffberg, and all other contributers for all you have done.
