           generate Ed25519 keys by default. Ed25519 public keys
           are very convenient due to their small size. Ed25519 keys are
           specified in RFC 8709 and OpenSSH has supported them since version 6.5
           (January 2014).
       <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
           the Subsystem directive now accurately preserves quoting of
           subsystem commands and arguments. This may change behaviour for exotic
           configurations, but the most common subsystem configuration
           (sftp-server) is unlikely to be affected.

     <li>...      <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
           add keystroke timing obfuscation to the client. This attempts
           to hide inter-keystroke timings by sending interactive traffic at
           fixed intervals (default: every 20ms) when there is only a small
           amount of data being sent. It also sends fake "chaff" keystrokes for
           a random interval after the last real keystroke. These are
           controlled by a new ssh_config ObscureKeystrokeTiming keyword.
       <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
           <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
           Introduce a transport-level ping facility. This adds
           a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
           implement a ping capability. These messages use numbers in the "local
           extensions" number space and are advertised using a "ping@openssh.com"
           ext-info message with a string version number of "0".
      <li>sshd(8): allow override of Subsystem directives in sshd Match blocks.

     <ul>      <ul>
     <li>...      <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
           fix scp in SFTP mode recursive upload and download of
           directories that contain symlinks to other directories. In scp mode,
           the links would be followed, but in SFTP mode they were not.
       <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
           handle cr+lf (instead of just cr) line endings in
           sshsig signature files.
       <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
           interactive mode for ControlPersist sessions if they
           originally requested a tty.
       <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
           make PerSourceMaxStartups first-match-wins
       <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
           limit artificial login delay to a reasonable maximum (5s)
           and don't delay at all for the "none" authentication mechanism.
       <li>sshd(8): Log errors in kex_exchange_identification() with level
           verbose instead of error to reduce preauth log spam. All of those
           get logged with a more generic error message by sshpkt_fatal().
       <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
           correct math for ClientAliveInterval that caused the probes
           to be sent less frequently than configured.
       <li>fix regression in OpenSSH 9.4 (mux.c r1.99) that caused
           multiplexed sessions to ignore SIGINT under some circumstances.
