Hello, Stellaris Community!

Europe swelters under the summer’s first heatwave, and yesterday we updated the 4.4.5 ‘Pegasus’ Open Beta on the stellaris_test branch with some more changes.

One of the big changes in this update is a revamp on the Automation menus for ships, intended to give you more control over what they’re doing. 

Harvest from empty space, not my friends.

The Return of our Ethical Refactoring

Well that title certainly sounds ominous.

Back in February, we briefly added a “risky” change to the 4.3 ‘Cetus’ Open Beta, relating to having mixed ethics within a single pop group. At the time we deemed it “not ready for release”, but we’re still interested in getting it into the 4.5 ‘Cygnus’ Custodian Update, as it’s absolutely essential for Willpower (releasing in 4.6).

Since it’s so important for our future plans, we want to put this through a longer Open Beta period, which means we’ll have two of them running at once.

The 4.5 ‘Cygnus’ Open Beta is a very early build, so includes a number of other experimental changes which may or may not make it to the final release - consider everything in this branch as tentative and yet to be balanced.

MacOS builds can also run 4.5 natively on Apple Silicon as a universal (arm64 + x86_64) binary, no longer requiring Rosetta 2 translation. We’d like to get stability and performance information from the community about this change. (Internally, it seems to be pretty nice.)

I was hoping to get the 4.5 Open Beta up alongside this dev diary, but we ran into some issues that we were still tracking down while I was writing this dev diary earlier this week. We hope to resolve those and have the 4.5 ‘Cygnus’ Open Beta available before the weekend on the stellaris_test_4.5 beta branch, though it may slip to early next week.

We expect to update the 4.5 ‘Cygnus’ Open Beta with more changes next week (a day or two after 4.4.5 releases). It’s looking like Nomadic Cosmogenesis and Storm Chasers might have first drafts in that update, along with some fixes to Nomadic Purge Vassals (and purging in general).

What’s Next?

Next week’s dev diary will focus on the 4.5 ‘Cygnus’ Open Beta update, and will be the last dev diary until August, though there are likely to be ongoing updates to the 4.5 Open Beta during July.

See you then!
