+Author: William Marlow <william.marlow@ibm.com>

+
+    Initial OpenSSL 3.0 support
+    
+    * Don't use deprecated functions when building against OpenSSL 3.0.
+    * Recognise that OpenSSL 3.0 can signal a dirty shutdown as a protocol.
+      error in addition to the expected IO error produced by OpenSSL 1.1.1
+    * Update regress_mbedtls.c for compatibility with OpenSSL 3
+
