+# Subject: [PATCH] [3.6] bpo-33127: Compatibility patch for LibreSSL 2.7.0
+# (GH-6210) (GH-6214)
+#
+# 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@××××××.org>.
+# (cherry picked from commit 4ca0739c9d97ac7cd45499e0d31be68dc659d0e1)
+
+# Co-authored-by: Christian Heimes <christian@××××××.org>
+# Patch modified by Aaron Bauman <bman@g.o> for 3.5.5
