Games and their developers seems to be in a never ending power struggle. When one update goes live, the team is already hard at work on the next. There's always a bug ready to be squashed, and it's the main focus of the next Stellaris patch - Stellaris 1.6 'Adams'.
Reportedly starting development the moment the Utopia expansion and its free 'Banks' update came along, the Paradox team already knew of a multitude of ways to tweak the game following the massive expansion. Having only launched on April 6, it's surprising to hear of another major update so soon - but it is without a release date right now.
Dev Diary #50 made not of a list of changes and a scaling list of priorities the Stellaris team had identified and outlined for their attention going forward. Calling it the time 'Beyond Utopia' there's already a preliminary list of what the 1.6 'Adams' update will bring - those with a strike-through have already been completed.
Much like the Banks and Utopia packs, patches going forward are either designed to squash bugs or introduce more ways to customise your empire or to tweak internal politics. Making special mention of the ability to build Dreadnoughts and Titans is a clear example of this.
The team will start talking about specifics over the next few weeks. And, of course, we'll update our patch page once the full list goes live. Until then, you'll just have to wait for the finer details.
