Looking at Debian’s release-critical bugs, you can see that Trixie is close:
Testing now has fewer critical bugs than Stable, and the number is dropping quickly.
About 200 bugs still need to be fixed to get the number down to where the previous releases were done.
Maybe you can help? Bugs blocking the next release can be as simple as missing translations for the upgrade instructions.
It’s been reported (Debian mailing list, Phoronix, Linuxiac) that Debian 13 will likely be out this summer. The hard freeze is on May 15 and usually that means the actual release is pretty close, just a couple of months away.
Phoronix speculated that ,since Debian 12 went from initial freeze to stable release in 5 months, Debian 13 could release around August.
