Please note, all future DCS World DLC released on Steam from 12th May 2017 on will now use Steam Keys instead of Star-Force keys.
Here are some modules released on Steam after 12-May-2017:
DCS: M-2000C; DCS: Nevada map; DCS: Spitfire; DCS: AJS-37; DCS: Normandy map; DCS: WW2 Assets pack; DCS: Su-33; DCS: AV-8B Night Attack V/STOL; DCS: F/A-18C; DCS: Persian Gulf map
as well as many new campaigns starting from the Museum Relic campaign.
You always can find the date in the Steam store - Sort by Release date
These modules can be bound and activated on the DCS World e-shop version from the site.
To do this, on the DCS website, on the profile page, find a special Steam account block

2) After logging in to the Steam site, you return to our site and, if successful, the "GET LICENSES" button will be available.
Click the "Get licenses" button.
3) As a result, you can obtain a list of the products whose licenses that:
1. Already have a DCS account (Steam or not Steam)
2. Can be transferred to your account from Steam
3. Can not be transferred because they are in different types of protection
4) Click the "Transfer licenses" button.
As a result, the licenses available for transfer will be bound to the DCS account.
5) When you re-enter this page, the Steam license list will be displayed.
6) You can request licenses again to replenish them if you purchased new DCS products on Steam. New licenses also can be bound, as in the previous paragraph.
7) When you click the "Unbind" button, all your Steam transferred licenses will be revoked and the binding removed.
