VMware upgraded ThinApp to version 4.0.2 a few days ago. Not much new outside of resolving and fixing a few bugs or issues.
The one addition that gets called out in the release notes is that the release adds the Wow64 parameter to the Package.ini file. You can use this parameter to help run 32-bit applications on a 64-bit Windows operating system.
