Yes, I just got the reply. Here it is:
Patches for third party games can only be distributed through Steam once the following two actions have occurred:
(1) The Publisher has provided us with the necessary files
(2) The Publisher has given us permission to release the update
The latest patches will be released as soon as possible, and will be downloaded automatically when available.
If you have questions about the availability of a specific patch, please contact the support department for the game in question.
Your patience is appreciated, please let us know if you have any other questions.
So it's Focus holding this up. Will someone at Larian PLEASE look into this?
