summary:
[2.7] bpo-33127: Compatibility patch for LibreSSL 2.7.0 (GH-6210) (GH-6215)
LibreSSL 2.7 introduced OpenSSL 1.1.0 API. The ssl module now detects
LibreSSL 2.7 and only provides API shims for OpenSSL < 1.1.0 and
LibreSSL < 2.7.
Documentation updates and fixes for failing tests will be provided in
another patch set.
Signed-off-by: Christian Heimes <christian at python.org>.
(cherry picked from commit 4ca0739c9d97ac7cd45499e0d31be68dc659d0e1)
