+ *) EGD is no longer supported by default; use enable-egd when
+ configuring.
+ [Ben Kaduk and Rich Salz]
+
+ *) The distribution now has Makefile.in files, which are used to
+ create Makefile's when Configure is run. *Configure must be run
+ before trying to build now.*
+ [Rich Salz]
+
+ *) The return value for SSL_CIPHER_description() for error conditions
+ has changed.

+
+ *) Support for RFC6698/RFC7671 DANE TLSA peer authentication.
+
+ Obtaining and performing DNSSEC validation of TLSA records is
+ the application's responsibility. The application provides
+ the TLSA records of its choice to OpenSSL, and these are then
+ used to authenticate the peer.
+
+ The TLSA records need not even come from DNS. They can, for
+ example, be used to implement local end-entity certificate or
+ trust-anchor "pinning", where the "pin" data takes the form
+ of TLSA records, which can augment or replace verification
+ based on the usual WebPKI public certification authorities.

+
+ *) Revert default OPENSSL_NO_DEPRECATED setting. Instead OpenSSL
+ continues to support deprecated interfaces in default builds.
+ However, applications are strongly advised to compile their
+ source files with -DOPENSSL_API_COMPAT=0x10100000L, which hides
+ the declarations of all interfaces deprecated in 0.9.8, 1.0.0
+ or the 1.1.0 releases.
+
+ In environments in which all applications have been ported to
+ not use any deprecated interfaces OpenSSL's Configure script
+ should be used with the --api=1.1.0 option to entirely remove
+ support for the deprecated features from the library and
+ unconditionally disable them in the installed headers.
+ Essentially the same effect can be achieved with the "no-deprecated"
+ argument to Configure, except that this will always restrict
+ the build to just the latest API, rather than a fixed API
+ version.
+
+ As applications are ported to future revisions of the API,
+ they should update their compile-time OPENSSL_API_COMPAT define
+ accordingly, but in most cases should be able to continue to
+ compile with later releases.
+
+ The OPENSSL_API_COMPAT versions for 1.0.0, and 0.9.8 are
+ 0x10000000L and 0x00908000L, respectively. However those
+ versions did not support the OPENSSL_API_COMPAT feature, and
+ so applications are not typically tested for explicit support
+ of just the undeprecated features of either release.
+ [Viktor Dukhovni]
+
+ *) Add support for setting the minimum and maximum supported protocol.
+ It can bet set via the SSL_set_min_proto_version() and
+ SSL_set_max_proto_version(), or via the SSL_CONF's MinProtocol and
+ MaxProtcol. It's recommended to use the new APIs to disable
+ protocols instead of disabling individual protocols using
+ SSL_set_options() or SSL_CONF's Protocol. This change also
+ removes support for disabling TLS 1.2 in the OpenSSL TLS
+ client at compile time by defining OPENSSL_NO_TLS1_2_CLIENT.
