Ok this is a pretty basic button, maybe kinda useless as u can see updates in this forum, but what about a changelog ingame that in it got the changes applied to game?
When you press the button, it will appear a big square in the screen that contains the changes, you can close Pressing the X (can be at right up corner or left up corner)
The Changelog will contain the Version at up while that the changes will remain at down
Example: (Very trash ik,)
Also it will be able to scroll down if u cant see all the changes, in left right there will be old versions that u can read their changelog that u didn’t read too.
