Yeah, it’s wild how many projects—especially container-based ones—have already jumped to Debian Trixie as their “stable” base, even though it’s still technically in testing. I got burned when linuxserver.io’s docker-webtop suddenly switched to Trixie and broke a bunch of my builds that were based on Bookworm.
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.
