Given how much new content is presented in Stellaris: Federations, we’d expect the latest patch notes to be fairly lengthy — and they are. Following on update 2.6.0, the so-called Verne update, is update 2.6.1. Originally offered as an opt-in beta, Steam users can download 2.6.1 right now.

ALSO: PS5 backwards compatibility looks like might be just for PS4 games

Chief among the Stellaris: Federations 2.6.1 patch notes are several balance adjustments. Repeatable technologies now apply all of their points toward Diplomatic Weight, and those effects have been increased. The Galatron also now increases Diplomatic Weight by 100 percent, while fleet power’s effect has on it been reduced.

Update 2.6.1 also introduces several changes to AI. Fleets now factor in enemies on route to targets, and will flee if resistance is too high. AI will also no longer ignore hostile forces in occupied systems, and will merge fleet groups whenever possible.

The changes here considerable, so be sure to go over all the latest details with the Stellaris: Federations patch notes for update 2.6.1 featured below.
