JH/30 Bug 1897: fix callouts connection fallback from TLS to cleartext.
+PP/01 Changed default Diffie-Hellman parameters to be Exim-specific, created
+ by me. Added RFC7919 DH primes as an alternative.
+
+PP/02 Unbreak build via pkg-config with new hash support when crypto headers
+ are not in the system include path.

Exim version 4.87
