When building with Jenkins, it is useful to store the build number in the project, so you can reference the version when reporting bugs and such.
Perhaps when packaging manually, it seems feasible to edit the Project Version in the game settings, but with an automated build system, it would be very beneficial to have an automated way of updating a major/minor version number or something similar.
And a follow up question:
is it possible to output the project version to the window title of the game? Currently it only shows the ProjectName from Config\DefaultGame.ini. In the game settings, it gives you the option to edit Project Displayed Title, but doesn’t mention a token for the project version.
