<!-- 2019/01/20 -->
<li>Adjusted mac filters to allow viewing vlan traffic and arp requests on vlans in <a href="https://man.openbsd.org/ixl">ixl(4)</a>.
<li>Added refresh for <a href="https://man.openbsd.org/arp">arp(8)</a> entries that are about to expire.
<li>Added support in <a href="https://man.openbsd.org/bgpd">bgpd(8)</a> and <a href="https://man.openbsd.org/bgpctl">bgpctl(8)</a> for group descriptions in control messages that accept a neighbor description.

<li>Added a -T option to test whether <a href="https://man.openbsd.org/ssh">ssh(1)</a> keys in an agent are usable.
<li>Imported xorgproto 2018.4.
<li>Added support for a new <a href="https://man.openbsd.org/kcov">kcov(4)</a> trace mode called KCOV_MODE_TRACE_CMP to trace comparison instructions and switch statements, usable during fuzzing to generate even more coverage.
<li>Set the shell to strip quotation marks from daemon_flags when starting a daemon with <a href="https://man.openbsd.org/rc.d>rc.d(8)</a>, making the details in pexp match what appears in the process list.

<li>Increased the socket buffer size for <a href="https://man.openbsd.org/sendsyslog">sendsyslog(2)</a> to 1 MB for fewer messages dropped by <a href="https://man.openbsd.org/syslogd">syslogd(8)</a>.

<li>Fix for <a href="https://man.openbsd.org/rcs">rcs(1)</a> to allow correct lock resolution before expansion of keywords, so expansion can happen with the correct values and files don't show up as modified.
<li>Added the ability for arm64 efiboot to boot from partitions other than "a".
<li>Spleen font enabled in <a href="https://man.openbsd.org/man8/wsfontload.8">wsfontload(8)</a>, along with font selection logic to allow selecting larger fonts when available at runtime in <a href="https://man.openbsd.org/rasops">rasops(9)</a>.
