I wouldn't expect much changes, if any a all, between today (Aug 5th) and the expected release date (Aug 9th).
As you said, Debian 13 officially lands on August 9, so it’s close—but in my (admittedly limited) experience, the testing branch still feels pretty rough. I ran into way more dependency chaos—and a bunch of missing or deprecated packages—than I expected.
If you’re relying on container images that have already moved to Trixie, heads up: it’s not quite seamless yet. Might be safer to stick with Bookworm a bit longer, or at least test thoroughly before making the jump.
Frankly, not waiting half a week is bright orange flag to me.
Finally, we provide bug and security updates for the previous stable release for over a year, so no user has any rush to upgrade now, they can safely choose any time between now and until August 2026.
