Hey folks, unfortunately Eladrin's been off ill this week, so we don’t have a full Dev Diary for this week. However I do have tentative patch notes for the 4.5.2 patch to share with you.

As always, thank you for playing Stellaris and giving us the feedback/bug reports, they help a great deal.

If all goes to plan, this should be released next week, on Tuesday, October 6th.

What’s Next?

Next week, Eladrin should be back (unless he’s still battling the Scourge).

See you then!
