Hello all,
The latest minor patch for Stellaris is ready and released, fixing a number of issues and further balancing the new mechanics.

We’re also planning a follow-up 3.9.3 patch for mid to late October, which will include some of the issues brought up during the Open Beta that require new text, more fixes that did not meet the 3.9.2 deadline, and a handful of other improvements.

Please find the patch notes below.
