Changes between 1.1.1a and 1.1.1b [xx XXX xxxx]
+ *) Added SCA hardening for modular field inversion in EC_GROUP through
+ a new dedicated field_inv() pointer in EC_METHOD.
+ This also addresses a leakage affecting conversions from projective
+ to affine coordinates.
+ [Billy Bob Brumley, Nicola Tuveri]
+
+ *) Change the info callback signals for the start and end of a post-handshake
+ message exchange in TLSv1.3. In 1.1.1/1.1.1a we used SSL_CB_HANDSHAKE_START
+ and SSL_CB_HANDSHAKE_DONE. Experience has shown that many applications get
+ confused by this and assume that a TLSv1.2 renegotiation has started. This
+ can break KeyUpdate handling. Instead we no longer signal the start and end
+ of a post handshake message exchange (although the messages themselves are
+ still signalled). This could break some applications that were expecting
+ the old signals. However without this KeyUpdate is not usable for many
+ applications.

*) Fix a bug in the computation of the endpoint-pair shared secret used
by DTLS over SCTP. This breaks interoperability with older versions
of OpenSSL like OpenSSL 1.1.0 and OpenSSL 1.0.2. There is a runtime
