+  *) Add a "destroy" handler to ENGINEs that allows structural cleanup to
+     be done prior to destruction. Use this to unload error strings from
+     ENGINEs that load their own error strings. NB: This adds two new API
+     functions to "get" and "set" this destroy handler in an ENGINE.
+     [Geoff]
+
+  *) Change the various "***_up()" functions, that increment reference
+     counts on the various structure types, to "***_up_ref()". The naming
+     is more consistent with existing code and generally a better choice.

+
+  *) Alter all existing ENGINE implementations (except "openssl" and
+     "openbsd") to dynamically instantiate their own error strings. This
+     makes them more flexible to be built both as statically-linked ENGINEs
+     and self-contained shared-libraries loadable via the "dynamic" ENGINE.
+     Also, add stub code to each that makes building them as self-contained
+     shared-libraries easier (see README.ENGINE).
+     [Geoff Thorpe]
+
+  *) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE
+     implementations into applications that are completely implemented in
+     self-contained shared-libraries. The "dynamic" ENGINE exposes control
+     commands that can be used to configure what shared-library to load and
+     to control aspects of the way it is handled. Also, made an update to
+     the README.ENGINE file that brings its information up-to-date and
+     provides some information and instructions on the "dynamic" ENGINE
+     (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc).

+     "ERR_unload_strings" function.
+     [Geoff Thorpe]

   *) Rabin-Miller test analyses assume uniformly distributed witnesses,
      so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
      followed by modular reduction.
