+  *) 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.

   *) Configuration change; it's now possible to build dynamic engines
-     without having to build shared libraries and vice versa.  The
-     only requirement for building dynamic engines is the presence of
-     the DSO module, so configuring "disable-dso" will automatically
-     disable dynamic engines.  Dynamic engines are enabled by default,
-     and can be disabled with "enable-static-engine".
-     This only applies to the engines in engines/, those in
-     crypto/engine/ will always be built into libcrypto (i.e. "static").

+     If this isn't desirable, the configuration options "disable-pic"
