I haven't tried but it did change Borderlands2.exe
It's another of those little mini-updates.

1.1.2
– Prevents data instability when launched with unsupported commands.
(Wouldn't a unsupported command be ignored?)
EDIT: Wonder if it does something else too, patch again changed a few other core files of the game instead of just the game exe and game launcher so maybe there's something else.

Whatever changes it made, it certainly didn't improve the new pink weapons. They still suck compared to most blue and purple weapons.
so far the new patch crashes my game with trainer, just fyi
same problem here, my game crashes too
