Trainer Tools and Resources
Seems the 1.1 patch is out for the retail edition now also, judging by that trainer list it seems the Steam edition was pretty frequently updated until recently.
Haven't found a way to see version information so I can't tell what exact build this is unfortunately but there it is incase there's any plans to update the trainer further for the retail version.
EDIT: Heh it was part of the file-name 3709
(Labeled as German on the site for some reason but it's likely inaccurate.)

EDIT: Updates the English version but does also support the German edition of the game with some localization specific fixes in addition to a number of bugfixes and enhancements.
