The OpenSSH 8.3 release is out. This primarily a bug-fix release with a
handful of minor new features. It does, however, carry a prominent notice
that ssh-rsa signature algorithm will be disabled in “a near-future
release“. The announcement includes information on how to determine
whether hosts you care about are affected.
