+Version 4.74
+------------
+
+ 1. SECURITY FIX: privilege escalation flaw fixed. On Linux (and only Linux)
+    the flaw permitted the Exim run-time user to cause root to append to
+    arbitrary files of the attacker's choosing, with the content based
+    on content supplied by the attacker.
+
+ 2. Exim now supports loading some lookup types at run-time, using your
+    platform's dlopen() functionality.  This has limited platform support
+    and the intention is not to support every variant, it's limited to
+    dlopen().  This permits the main Exim binary to not be linked against
+    all the libraries needed for all the lookup types.

 12. [POSSIBLE CONFIG BREAKAGE] ALT_CONFIG_ROOT_ONLY is no longer optional and
     is forced on.  This is mitigated by the new build option
-    TRUSTED_CONFIG_PREFIX_LIST which defines a list of pathname prefices which
-    are trusted; if a config file is owned by root and is under that prefix,
-    then it may be used by the Exim run-time user.
+    TRUSTED_CONFIG_LIST which defines a list of configuration files which
+    are trusted; one per line. If a config file is owned by root and matches
+    a pathname in the list, then it may be invoked by the Exim build-time
+    user without Exim relinquishing root privileges.
 
 13. [POSSIBLE CONFIG BREAKAGE] The Exim user is no longer automatically
     trusted to supply -D<Macro[=Value]> overrides on the command-line.  Going
-    forward, we recommend using TRUSTED_CONFIG_PREFIX_LIST with shim configs
-    that include the main config.  As a transition mechanism, we are
-    temporarily providing a work-around: the new build option
-    WHITELIST_D_MACROS provides a colon-separated list of macro names which
-    may be overriden by the Exim run-time user.  The values of these macros
-    are constrained to the regex ^[A-Za-z0-9_/.-]*$ (which explicitly does
-    allow for empty values).
