  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.
