Team Fusion’s work is now offered as an official content update and patch for Cliffs of Dover on Steam, that includes all the current changes and fixes. There is now no need to download Team Fusion patches one by one and install them manually. If you already have your Cliffs of Dover updated with the previous TF patches (version 4.312) you do not need to download this new patch. All this patch does is combine all previous patches into one.
The update is optional for now. To enable it, right-click on IL-2 Sturmovik: Cliffs of Dover entry in your Steam library and choose Properties. Once there, go to the Betas tab and choose 'teamfusionupdate' entry from the drop-down list. That's it - Steam should start the download shortly. When it finishes, your version of the game is updated with the latest Team Fusion patch (version 4.312).
In the near future, this update will be codified by Team Fusion and officially entered into the source code and file system for the product itself. The title will then be permanently updated through Steam negating the need for a separate patch. Again, this will come later this year.
