I don't have an answer to the question of the next patch title, but I
would like to hear some progress news from the team too.
I know work is continuing on a number of proposed new maps, objects and bug fixes, so this
should mean the patches will continue.
Other than that I've seen no news from the team since the 4.15.1 release, when they said that work was still continuing on the C-47 family and some other aircraft.
