I agree that Larian really should put version numbers on their patch release notes, so we can be sure.
Version 1.4.9.65 was definitely patch 1 - I immeditately noticed the difference in some of my enchantments.
The problem with patch 2 was that it didn't change anything in the gameplay (at leat not that they announced), it was just a fix for some graphics issues and bugs that seemed to result from patch 1. I never had any issues with any version, so I can't tell if they were fixed.
Either way, there was a second steam patch to version 1.4.9.70 - but whether this is actually "patch 2" or just a fix for the Steam version of Patch 1 is something Larian will have to advise.
