For all of our programs except WinRescue, the Upgrade/Update and Download Registered Version options take you to the same place.
We only keep the latest versions on our website. So if you downloaded it from our website, it is the latest version.
You did not say which program you are inquiring about so I cannot tell you if that is the latest date or not.
The download page has a box at the bottom titled - Latest Version Number. The link there will take you to information about the latest version which includes the date. Just do not download the program from the links in the latest version information page because you will get the trial version instead of the registered version.
