Yes - I think Trolltech probably assume people will be distributing the Qt
DLL with their apps on Windows so it doesn't matter about the version
granularity. However because Qt/Win Free is GPL people would not only have
to distribute the Qt DLL with their apps, but also make the full source
available. Far better to get people to simply point users to the kde-cygwin
site to download the binary and source. However if we adopt this policy it
would be better to switch to only using the major version number, as you
say, so that people can always download the latest version without any
