> Features
> - Pass the comm_reply information to the inplace_cb_reply* functions
>    during the mesh state and update the documentation on that.
> - Fix #330: [Feature request] Add unencrypted DNS over HTTPS support.
>    This adds the option http-notls-downstream: yesno to change that,
>    and the dohclient test code has the -n option.
> - Merge PR #228 : infra-keep-probing option to probe hosts that are
>    down.  Add infra-keep-probing: yes option. Hosts that are down are
>    probed more frequently.
>    With the option turned on, it probes about every 120 seconds,
>    eventually after exponential backoff, and that keeps that way. If
>    traffic keeps up for the domain. It probes with one at a time, eg.
>    one query is allowed to probe, other queries within that 120 second
>    interval are turned away.
> - Merge PR #313 from Ralph Dolmans: Replace edns-client-tag with
>    edns-client-string option.
> - Merge PR #283 : Stream reuse.  This implements upstream stream
>    reuse for performing several queries over the same TCP or TLS
>    channel.
> - Fix to connect() to UDP destinations, default turned on,
>    this lowers vulnerability to ICMP side channels.
>    Option to toggle udp-connect, default is enabled.

> Bug Fixes
> - Fix #319: potential memory leak on config failure, in rpz config.
> - Fix dnstap socket and the chroot not applied properly to the dnstap
>    socket path.
> - Fix warning in libnss compile, nss_buf2dsa is not used without DSA.
> - Fix #323: unbound testsuite fails on mock build in systemd-nspawn
>    if systemd support is build.
> - Fix for python reply callback to see mesh state reply_list member,
>    it only removes it briefly for the commpoint call so that it does
>    not drop it and attempt to modify the reply list during reply.
> - Fix that if there are on reply callbacks, those are called per
>    reply and a new message created if that was modified by the call.
> - Free up auth zone parse region after use for lookup of host
> - Merge PR #326 from netblue30: DoH: implement content-length
>    header field.
> - DoH content length, simplify code, remove declaration after
>    statement and fix cast warning.
> - Fix that if there are reply callbacks for the given rcode, those
>    are called per reply and a new message created if that was modified
>    by the call.
> - Fix that the out of order TCP processing does not limit the
>    number of outstanding queries over a connection.
> - Fix python documentation warning on functions.rst inplace_cb_reply.
> - Log ip address when http session recv fails, eg. due to tls fail.
> - Fix to set the tcp handler event toggle flag back to default when
>    the handler structure is reused.
> - Clean the fix for out of order TCP processing limits on number
>    of queries.  It was tested to work.
> - Fix that http settings have colon in set_option, for
>    http-endpoint, http-max-streams, http-query-buffer-size,
>    http-response-buffer-size, and http-nodelay.
> - Fix memory leak of https port string when reading config.

>    custom region alloc init.
> - Fix #333: Unbound Segmentation Fault w/ log_info Functions From
