 - Supported versions:

+  - TLS 1.2 and TLS 1.3 but version negotiation is not supported.
 
-  - TLS 1.3 and 1.2 can be disable/enable with build option. One of them MUST be
-    enabled. Supported build options:
+  - TLS 1.3 can be enabled in the build (MBEDTLS_SSL_PROTO_TLS1_3 configuration
+    option) without TLS 1.2 (MBEDTLS_SSL_PROTO_TLS1_2 configuration option).
