+ 7. It has always been implicit in the design and the documentation that
+    "the Exim user" is not root.  src/EDITME said that using root was
+    "very strongly discouraged".  This is not enough to keep people from
+    shooting themselves in the foot in days when many don't configure Exim
+    themselves but via package build managers.  The security consequences of
+    running various bits of network code are severe if there should be bugs in
+    them.  As such, the Exim user may no longer be root.  If configured
+    statically, Exim will refuse to build.  If configured as ref:user then Exim
+    will exit shortly after start-up.  If you must shoot yourself in the foot,
+    then henceforth you will have to maintain your own local patches to strip
+    the safeties off.
+
+ 8. There is a new expansion operator, bool_lax{}.  Where bool{} uses the ACL
+    condition logic to determine truth/failure and will fail to expand many
+    strings, bool_lax{} uses the router condition logic, where most strings
+    do evaluate true.
+    Note: bool{00} is false, bool_lax{00} is true.
