Most up to date P22?

Can anyone tell me what the most up to date build version number of Painter 22 for Mac OS is?

Reason I ask is that I’ve done a clean instal of my machine and am reinstalling the app now.  Installed P22 and checked for updates through the built in app update menu and it says none are available.  I do know that there was an update/hot fix released for 22 at sometime but it doesn’t appear to showing up.

any insight would be welcome.  Thanks all.
