Hi all, Jamor here with some good news: Stellaris: Adams Update 1.6 is live right now!

The timing of this update is very symbolic for us, as it marks the one year anniversary of Stellaris being unleashed upon the galaxy. We've come a long way since release and we're happy to have you with us on this ongoing journey.

While there are some small content additions, our main concept for this update was housekeeping and quality of life: the sheer number of new features we've added since launch has inevitably caused some things to work less perfectly than we want, so we have put in hundreds of bug fixes and quality of life improvements to improve your play experience.

To really celebrate our anniversary in style we're rolling out an Anniversary Edition bundle today, containing the base game plus all expansions to date. For those new to our universe, it's the most complete option to start your journey, and for our existing players it's a great way to upgrade your experience with a nice discount.

And finally, it is my very great privilege to announce a gift to all our players: a free DLC anniversary portrait pack, including the Creatures of the Void preorder species portraits plus three new ones made specially for the anniversary:



Please accept this as our sincere thanks to you all for a year of interstellar adventure, and come along with us as we continue our voyage into the endless stars.

******* IMPORTANT! ********
Saves from 1.5.1 should work in 1.6.0, however we couldn't test every possible case and it's possible some issues may occur. If that happens to you in a game you want to complete, you can always roll back to a previous version.
