I believe that former version will unmask only given version while 
latter version will unmask all unstable versions of fontforge, forcing 
users to update every time new version is available. So, using former 
version, x86 keyworded systems will be updated to 20060406 version, and 
will stay on it until more recent version will be marked as stable.
