</ul>
</ul>
<li>OpenSSH 8.1
<ul>
<li>New Features
<ul>
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: Allow %n to be
expanded in ProxyCommand strings
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>,
<a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>: Allow
prepending a list of algorithms to the default set by
starting the list with the '^' character, E.g.
"HostKeyAlgorithms ^ssh-ed25519"
<li><a href='https://man.openbsd.org/ssh-keygen.1'>ssh-keygen(1)</a>:
add an experimental lightweight signature and verification
ability. Signatures may be made using regular ssh keys held
on disk or stored in a ssh-agent and verified against an
authorized_keys-like list of allowed keys. Signatures embed
a namespace that prevents confusion and attacks between
different usage domains (e.g. files vs email).
<li><a href='https://man.openbsd.org/ssh-keygen.1'>ssh-keygen(1)</a>:
print key comment when extracting public key from a private
key. <a href='https://bugzilla.mindrot.org/show_bug.cgi?id=3052'>bz#3052</a>
<li><a href='https://man.openbsd.org/ssh-keygen.1'>ssh-keygen(1)</a>:
accept the verbose flag when searching for host keys in
known hosts (i.e. "ssh-keygen -vF host") to print the
matching host's random-art signature
too. <a href='https://bugzilla.mindrot.org/show_bug.cgi?id=3003'>bz#3003</a>
<li>All: support PKCS8 as an optional format for storage of
private keys to disk. The OpenSSH native key format remains
the default, but PKCS8 is a superior format to PEM if
interoperability with non-OpenSSH software is required, as
it may use a less insecure key derivation function than
PEM's.
</ul>
<li>Bugfixes
<ul>
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: if a
PKCS#11 token returns no keys then try to login and
refetch them. Based on patch from Jakub
Jelen; <a href='https://bugzilla.mindrot.org/show_bug.cgi?id=2430'>bz#2430</a>
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>:
produce a useful error message if the user's shell is set
incorrectly during "match exec"
processing. <a href='https://bugzilla.mindrot.org/show_bug.cgi?id=2791'>bz#2791</a>
<li><a href='https://man.openbsd.org/sftp.1'>sftp(1)</a>:
allow the maximum uint32 value for the argument passed to
-b which allows better error messages from later
validation.
<a href='https://bugzilla.mindrot.org/show_bug.cgi?id=3050'>bz#3050</a>
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>:
avoid pledge sandbox violations in some combinations of
remote forwarding, connection multiplexing and
ControlMaster.
<li><a href='https://man.openbsd.org/ssh-keyscan.1'>ssh-keyscan(1)</a>:
include SHA2-variant RSA key algorithms in KEX proposal;
allows ssh-keyscan to harvest keys from servers that
disable old SHA1
ssh-rsa. <a href='https://bugzilla.mindrot.org/show_bug.cgi?id=3029'>bz#3029</a>
<li><a href='https://man.openbsd.org/sftp.1'>sftp(1)</a>:
print explicit "not modified" message if a file was
requested for resumed download but was considered already
complete.
<a href='https://bugzilla.mindrot.org/show_bug.cgi?id=2978'>bz#2978</a>
<li><a href='https://man.openbsd.org/sftp.1'>sftp(1)</a>:
fix a typo and make <esc><right> move right to the
closest end of a word just like <esc><left> moves
left to the closest beginning of a word.
<li><a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>:
cap the number of permitopen/permitlisten directives
allowed to appear on a single authorized_keys line.
<li>All: fix a number of memory leaks (one-off or on exit paths).
<li>Regression tests: a number of fixes and improvements,
including fixes to the interop tests, adding the ability
to run most tests on builds that disable OpenSSL support,
better support for running tests under Valgrind and a
number of bug-fixes.
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>,
<a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>:
check for convtime() refusing to accept times that resolve
to LONG_MAX Reported by Kirk Wolf bz2977
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>:
slightly more instructive error message when the user
specifies multiple -J options on the command-line. bz3015
<li><a href='https://man.openbsd.org/ssh-agent.1'>ssh-agent(1)</a>:
process agent requests for RSA certificate private keys
using correct signature algorithm when requested. bz3016
<li><a href='https://man.openbsd.org/sftp.1'>sftp(1)</a>:
check for user@host when parsing sftp target. This allows
user@[1.2.3.4] to work without a
path. <a href='https://bugzilla.mindrot.org/show_bug.cgi?id=2999'>bz#2999</a>
<li><a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>:
enlarge format buffer size for certificate serial number
so the log message can record any 64-bit integer without
truncation. <a href='https://bugzilla.mindrot.org/show_bug.cgi?id=3012'>bz#3012</a>
<li><a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>:
for PermitOpen violations add the remote host and port to
be able to more easily ascertain the source of the
request. Add the same logging for PermitListen violations
which where not previously logged at all.
<li><a href='https://man.openbsd.org/scp.1'>scp(1)</a>,
<a href='https://man.openbsd.org/sftp.1'>sftp(1)</a>:
use the correct POSIX format style for left justification
for the transfer progress
meter. <a href='https://bugzilla.mindrot.org/show_bug.cgi?id=3002'>bz#3002</a>
<li><a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>
when examining a configuration using sshd -T, assume any
attribute not provided by -C does not match, which allows
it to work when sshd_config contains a Match directive
with or without -C.
<a href='https://bugzilla.mindrot.org/show_bug.cgi?id=2858'>bz#2858</a>
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>,
<a href='https://man.openbsd.org/ssh-keygen.1'>ssh-keygen(1)</a>:
downgrade PKCS#11 "provider returned no slots" warning
from log level error to debug. This is common when
attempting to enumerate keys on smartcard readers with no
cards plugged
in. <a href='https://bugzilla.mindrot.org/show_bug.cgi?id=3058'>bz#3058</a>
<li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>,
<a href='https://man.openbsd.org/ssh-keygen.1'>ssh-keygen(1)</a>:
do not unconditionally log in to PKCS#11 tokens. Avoids
spurious PIN prompts for keys not selected for
authentication
in <a href='https://man.openbsd.org/ssh.1'>ssh(1)</a> and
when listing public keys available in a token
using <a href='https://man.openbsd.org/ssh-keygen.1'>ssh-keygen(1)</a>.
<a href='https://bugzilla.mindrot.org/show_bug.cgi?id=3006'>bz#3006</a>
</ul>
</ul>
<li>Mandoc
<ul>
<li>Slowly start implementing tagging support for
<a href="https://man.openbsd.org/man.7">man(7)</a> pages:
tag alphabetic arguments of <code>.IP</code>, <code>.TP</code>,
and <code>.TQ</code> macros.
<li>In HTML output, wrap text and phrasing elements in paragraphs
unless already contained in flow containers; never put them
directly into sections. This helps to format paragraphs with
the CSS class selector <code>.Pp</code>.
<li>Implement the <a href="https://man.openbsd.org/roff.7">roff(7)</a>
<code>.break</code> request to break out of a <code>.while</code>
loop.
<li>If messages are shown and output is printed without a pager,
display a heads-up on standard error output at the end because
otherwise, users may easily miss the messages.
<li>Let <code>mandoc.css</code> support
<code>prefers-color-scheme: dark</code>.

<a href="https://man.openbsd.org/man.1">man(1)</a>
show the NAME section.
