Previously, when added to the Steam library, free games and add-ons began to automatically download. From now on, users have a choice!
On the project pages, next to the “Play” button that starts the download, there is an Add to Library button – it adds a game or DLC to the library, but does not start the installation after clicking.
In addition, some extensions, when added to the library, launched the game – this should not be the case now.
