The full version is in the About Box, which is pretty standard for most computer
software.
You can programmatically query the third digit by evaluating $ReleaseNumber,
which is fully documented.
I'm not sure what information about third digit upgrades is on the website, but
Wikipedia about articles about major software packages quite often include this
level of information, and the one on Mathematica does, too. Minor version
upgrades are generally mentioned on this forum, as well.
Sincerely,
