* 2020-0?-??: Version 1.6.1-rc.1
* 2021-06-??: Version 1.7.0
* Make TLS Handshake timeout max 4/5th of timeout for the query,
just like connection setup timeout was, so fallback transport
have a chance too when TCP connection setup is less well
detectable (as with TCP_FASTOPEN on MacOS).
* Issue #466: Memory leak with retrying queries (for examples
with search paths). Thanks doublez13.
* Issue #480: Cross compiling is broken with CMake
* Issue #480: Handling of strptime when Cross compiling with CMake.
A new option to FORCE_COMPAT_STRPTIME (default disabled) will
(when disabled) make cmake assume the target platform has a POSIX
compatible strptime when cross-compiling.
* Setting of the number of milliseconds send data may remain
unacknowledged by the peer in a TCP connection (when supported
by the OS) with getdns_context_set_tcp_send_timeout()
Thanks maciejsszmigiero.
* Issue #497: Fix typo in CMAKE included files, so Stubby can use
TLS v1.3 with chipersuites options ON. Thanks har-riz.
* Basic name compression on server replied messages. Thanks amialkow!
This alleviates (but might not completely resolve) issues #495 and
#320 .
* 2020-02-28: Version 1.6.0
* Issues #457, #458, #461: New symbols with libnettle >= 3.4.
