<h3>Changes made between OpenBSD 7.1 and -current</h3>
<p>

<ul>

<li>Implemented a <code>max-communities</code> filter match for <a href="https://man.openbsd.org/bgpd.conf.5">bgpd.conf(5)</a>.
<!-- 2022/05/30 -->
<li>Added <a href="https://man.openbsd.org/sfgpio.4">sfgpio(4)</a>, a driver for the GPIO controller found on the SiFive FU740 SoC.
<li>Made <a href="https://man.openbsd.org/grep.1">grep(1)</a> provide full context when using match count (<code>-m</code>).
<li>Added an ACL list for multiple users attaching to the <a href="https://man.openbsd.org/tmux.1">tmux(1)</a> socket.
<li>Made a first pass at providing kstats for <a href="https://man.openbsd.org/mvneta.4">mvneta(4)</a> from the hardware counters.
<!-- 2022/05/29 -->
<!-- 2022/05/28 -->
<!-- 2022/05/27 -->

<!-- 2022/05/26 -->
<li>Made <a href="https://man.openbsd.org/ssh.1">ssh(1)</a> unconditionally call <a href="https://man.openbsd.org/freezero.3">freezero(3)</a> to guarantee that the password is removed from RAM even when sshpkt functions fail.
<li>Introduced a new daemon_execdir variable to <a href="https://man.openbsd.org/rc.d.8">rc.d(8)</a> for changing to a specified directory before running rc_exec.
