There are some reports that Apple has quietly released 10.3.1 update, which appears to be only for the Mac OS.
If we check 10.3 and do update we are told that 10.3 is the latest version.
If we check the about it reads 10.3.0.54.
We will wait to see what happens.
I’m checking 10.3 on a Mac now as well.
Apple iTunes 10.3 can be downloaded here
