OpenSSL 1.1.1 was released today. The blog post lists all major improvements.

* TLS 1.3
* API and ABI compatible with OpenSSL 1.1.0
* LTS release (support schedule TBD)

All tests on master are passing with OpenSSL 1.1.1. I still want to hold off and wait a couple of patch releases, before we start to ship Windows and macOS builds with 1.1.1. Some aspects of the TLS 1.3 handshake are different to TLS 1.2. I might have to implement some additional APIs for post handshake authentication.

Hi macOS and Windows devs,

as I explained in we need to update Python 3.7 to OpenSSL 1.1.1 eventually. 1.1.0 will reach EOL in September.

[From the cited python-dev email]:

"Python 3.7 and master (3.8) are affected. As of now, both branches use
OpenSSL 1.1.0 and must be updated to 1.1.1 soonish. Ned has scheduled
3.7.3 release for 2019-03-25. That's still well within the release
schedule for 1.1.0. I suggest that we update to 1.1.1 directly after the
release of Python 3.7.3 and target 3.7.4 as first builds with TLS 1.3
support. That gives Victor, Steve, and me enough time to sort out the
remaining issues."

So setting the priority here to "deferred blocker" as a reminder to take care of this prior to 3.8.0b1 (2019-05-26) and 3.7.4rc1 (2019-06-10) at the latest.
