Choose affected toolFAQ
Are these launch patch notes?
This is an official announcement timeline. The newest entries cover invited Final Beta access and pre-download; the remaining entries mainly cover official reveal, Coziness Test, and Stardrift Test notices.
Why track test updates?
They explain which systems appeared in public official posts and help players avoid mixing closed-test dates with launch information.
What is the latest tracked official notice?
The latest checks describe invited Final Beta pre-download from September 19 and a September 20 test start, alongside the Winter 2026 public window; the September 14 prize-draw deadline has passed.
Do patch notes confirm database values?
No. Patch notes can confirm official status or test context, while fish, recipe, gift, and furniture values still need current-build checks.
Should I treat closed-test changes as launch rules?
No. Coziness and Stardrift notes are test context until a public build or official launch notice confirms the same rule.
Where should I verify a new update?
Open the official source link first, then check whether the notice affects release, download, platforms, events, or database pages.
