+ Changes between 1.0.2f and 1.1.0 [xx XXX xxxx]
+
+ *) Deprecate SRP_VBASE_get_by_user.
+ SRP_VBASE_get_by_user had inconsistent memory management behaviour.
+ In order to fix an unavoidable memory leak (CVE-2016-0798),
+ SRP_VBASE_get_by_user was changed to ignore the "fake user" SRP
+ seed, even if the seed is configured.
+
+ Users should use SRP_VBASE_get1_by_user instead. Note that in
+ SRP_VBASE_get1_by_user, caller must free the returned value. Note
+ also that even though configuring the SRP seed attempts to hide
+ invalid usernames by continuing the handshake with fake
+ credentials, this behaviour is not constant time and no strong
+ guarantees are made that the handshake is indistinguishable from
+ that of a valid user.
+ [Emilia Käsper]
+
+ *) Configuration change; it's now possible to build dynamic engines
+ without having to build shared libraries and vice versa. This
+ only applies to the engines in engines/, those in crypto/engine/
+ will always be built into libcrypto (i.e. "static").
+
+ Building dynamic engines is enabled by default; to disable, use
+ the configuration option "disable-dynamic-engine".
+
+ The only requirements for building dynamic engines are the
+ presence of the DSO module and building with position independent
+ code, so they will also automatically be disabled if configuring
+ with "disable-dso" or "disable-pic".
+
+ The macros OPENSSL_NO_STATIC_ENGINE and OPENSSL_NO_DYNAMIC_ENGINE
+ are also taken away from openssl/opensslconf.h, as they are
+ irrelevant.
+ [Richard Levitte]
+
+ *) Configuration change; if there is a known flag to compile
+ position independent code, it will always be applied on the
+ libcrypto and libssl object files, and never on the application
+ object files. This means other libraries that use routines from
+ libcrypto / libssl can be made into shared libraries regardless
+ of how OpenSSL was configured.
+
+ If this isn't desirable, the configuration options "disable-pic"
+ or "no-pic" can be used to disable the use of PIC. This will
+ also disable building shared libraries and dynamic engines.
+ [Richard Levitte]
+
+ *) Removed JPAKE code. It was experimental and has no wide use.
+ [Rich Salz]
+
+ *) The INSTALL_PREFIX Makefile variable has been renamed to
+ DESTDIR. That makes for less confusion on what this variable
+ is for. Also, the configuration option --install_prefix is
+ removed.
+ [Richard Levitte]
+
+ *) Heartbeat for TLS has been removed and is disabled by default
+ for DTLS; configure with enable-heartbeats. Code that uses the
+ old #define's might need to be updated.
+ [Emilia Käsper, Rich Salz]
+
+ *) Rename REF_CHECK to REF_DEBUG.
+ [Rich Salz]
+
+ *) New "unified" build system
+
+ The "unified" build system is aimed to be a common system for all
+ platforms we support. With it comes new support for VMS.
+
+ This system builds supports building in a different directory tree
+ than the source tree. It produces one Makefile (for unix family
+ or lookalikes), or one descrip.mms (for VMS).
+
+ The source of information to make the Makefile / descrip.mms is
+ small files called 'build.info', holding the necessary
+ information for each directory with source to compile, and a
+ template in Configurations, like unix-Makefile.tmpl or
+ descrip.mms.tmpl.
+
+ We rely heavily on the perl module Text::Template.
+ [Richard Levitte]
+
+ *) Added support for auto-initialisation and de-initialisation of the library.
+ OpenSSL no longer requires explicit init or deinit routines to be called,
+ except in certain circumstances. See the OPENSSL_init_crypto() and
+ OPENSSL_init_ssl() man pages for further information.
+ [Matt Caswell]
+
+ *) The arguments to the DTLSv1_listen function have changed. Specifically the
+ "peer" argument is now expected to be a BIO_ADDR object.
+
+ *) Rewrite of BIO networking library. The BIO library lacked consistent
+ support of IPv6, and adding it required some more extensive
+ modifications. This introduces the BIO_ADDR and BIO_ADDRINFO types,
+ which hold all types of addresses and chains of address information.
+ It also introduces a new API, with functions like BIO_socket,
+ BIO_connect, BIO_listen, BIO_lookup and a rewrite of BIO_accept.
+ The source/sink BIOs BIO_s_connect, BIO_s_accept and BIO_s_datagram
+ have been adapted accordingly.
+ [Richard Levitte]
+
+ *) RSA_padding_check_PKCS1_type_1 now accepts inputs with and without
+ the leading 0-byte.
+ [Emilia Käsper]
+
+ *) CRIME protection: disable compression by default, even if OpenSSL is
+ compiled with zlib enabled. Applications can still enable compression
+ by calling SSL_CTX_clear_options(ctx, SSL_OP_NO_COMPRESSION), or by
+ using the SSL_CONF library to configure compression.
+ [Emilia Käsper]
+
+ *) The signature of the session callback configured with
+ SSL_CTX_sess_set_get_cb was changed. The read-only input buffer
+ was explicitly marked as 'const unsigned char*' instead of
+ 'unsigned char*'.
+ [Emilia Käsper]
+
+ *) Always DPURIFY. Remove the use of uninitialized memory in the
+ RNG, and other conditional uses of DPURIFY. This makes -DPURIFY a no-op.
+ [Emilia Käsper]
+
+ *) Removed many obsolete configuration items, including
+ DES_PTR, DES_RISC1, DES_RISC2, DES_INT
+ MD2_CHAR, MD2_INT, MD2_LONG
+ BF_PTR, BF_PTR2
+ IDEA_SHORT, IDEA_LONG
+ RC2_SHORT, RC2_LONG, RC4_LONG, RC4_CHUNK, RC4_INDEX
+ [Rich Salz, with advice from Andy Polyakov]
+
+ *) Many BN internals have been moved to an internal header file.
+ [Rich Salz with help from Andy Polyakov]
+
+ *) Configuration and writing out the results from it has changed.
+ Files such as Makefile include/openssl/opensslconf.h and are now
+ produced through general templates, such as Makefile.in and
+ crypto/opensslconf.h.in and some help from the perl module
+ Text::Template.
+
+ Also, the center of configuration information is no longer
+ Makefile. Instead, Configure produces a perl module in
+ configdata.pm which holds most of the config data (in the hash
+ table %config), the target data that comes from the target
+ configuration in one of the Configurations/*.conf files (in
+ %target).
