Among other changes 10.4 adds post-quantum keys (composite ML-DSA 44 and Ed25519), not enabled by default.
When pq key agreement was added in 2019, it took almost 3 years for it to become enabled by default. This isn't criticism, just an observation. I don't have a pressing need for pq sigs. Always happy for new OpenSSH releases though!

The draft was only published a few months ago:

The draft is a 'personal document', so not associated with the IETF/WG.

Still looks like ascii, doesn’t automatically wrap, nor is it responsive.
Anyone know if these projects accept PRs to improve these kinds of things, like legibility? Or is it a point of pride?
Is hmac-sha1 and umac-64 still enabled by default?
Yes:
* https://man.openbsd.org/ssh_config.5#MACs
* https://man.openbsd.org/sshd_config.5#MACs
ETM, encrypt-than-mac, variants are at the front of the preference list.
