Full release notes are available at https://www.openssh.com/txt/release-10.1 Selected highlights from the release notes: Potentially-incompatible changes * ssh(1): add a warning when the connection negotiates a non-post quantum key agreement algorithm. * ssh(1), sshd(8): major changes to handling of DSCP marking/IPQoS * ssh(1), sshd(8): deprecate support for IPv4 type-of-service (ToS) keywords in the IPQoS configuration directive. * ssh-add(1): when adding certificates to an agent, set the expiry to the certificate expiry time plus a short (5 min) grace period. * ssh-agent(1), sshd(8): move agent listener sockets from /tmp to under ~/.ssh/agent for both ssh-agent(1) and forwarded sockets in sshd(8). Security * ssh(1): disallow control characters in usernames passed via the commandline or expanded using %-sequences from the configuration file, and disallow \0 characters in ssh:// URIs. New features * ssh(1), sshd(8): add SIGINFO handlers to log active channel and session information. Sponsored by: The FreeBSD Foundation
