>    and the dohclient test code has the -n option.

>    probed more frequently.

> - Merge PR #313 from Ralph Dolmans: Replace edns-client-tag with

> - Merge PR #283 : Stream reuse.  This implements upstream stream

> - Fix to connect() to UDP destinations, default turned on,
>    this lowers vulnerability to ICMP side channels.
>    Option to toggle udp-connect, default is enabled.

> - 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,
