You need to consider if there is anything you absolutely need in a new version. To quote that little fat pink professor woman from Harry Potter: “Progress for progess’ sake must be avoided”. I am still with 4.22 because there is nothing in 4.23 ir 4.24 I would use and the bugs just aren’t worth it. Unless I read here that there is a version in the near future that is working without major problem, I will be releasing my game with 4.22.
The marketplace guys tell us that they are only allowed to post product updates for the last 3 Unreal versions and I suspect that is an underhanded trick by Epic to force people to upgrade just to be able to buy the newest assets.
