+Subject: [PATCH] Only set min_version on OpenSSL < 1.1.0
+
+Both Red Hat and Debian-like systems configure the minimum TLS version
+to be 1.2 by default, but allow users to change this via configs.
+
+On Red Hat and derivatives this happens via crypto-policies[1], which in
+writes settings in /etc/crypto-policies/back-ends/opensslcnf.config.
+Most notably, it sets TLS.MinProtocol there. For Debian there's
+MinProtocol in /etc/ssl/openssl.cnf. Both default to TLSv1.2, which is
+considered a secure default.
+
+In constrast, the SSLContext has a hard coded OpenSSL::SSL::TLS1_VERSION
+for min_version. TLS 1.0 and 1.1 are considered insecure. By always
+setting this in the default parameters, the system wide default can't be
+respected, even if a developer wants to.
+
+This takes the approach that's also done for ciphers: it's only set for
+OpenSSL < 1.1.0.
