This is a high-level summary of the most important changes. For a full list of changes, see the git commit log; for example, https://github.com/openssl/openssl/commits/ and pick the appropriate release branch.

Changes between 1.1.1a and 1.1.1b [26 Feb 2019]

*) 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. [Matt Caswell]

*) 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 switch SSL_MODE_DTLS_SCTP_LABEL_LENGTH_BUG (off by default) enabling interoperability with such broken implementations. However, enabling this switch breaks interoperability with correct implementations.

*) Fix a use after free bug in d2i_X509_PUBKEY when overwriting a

re-used X509_PUBKEY object if the second PUBKEY is malformed. [Bernd Edlinger]

*) Move strictness check from EVP_PKEY_asn1_new() to EVP_PKEY_asn1_add0().

[Richard Levitte]

*) Remove the 'dist' target and add a tarball building script. The

'dist' target has fallen out of use, and it shouldn't be necessary to configure just to create a source distribution. [Richard Levitte]
