Stellaris' patch 3.9 is a product of the Custodian initiative, whose establishment saw the grand strategy game's development team split into two.
Stellaris Patch 3.9 Release Date
One half focuses on paid expansion content, while another hacks away at ensuing free patches release every 3 months or so.
This is useful when trying to determine the update's release date, even before Paradox announces it. The Gemini update went live in the first half of May 2023.
We currently expect update 3.9 to arrive at some point in fall 2023 and the developer has confirmed that to be the case.
