   * The server still does not always require (or print) the `::` prefix.  That will change.
 * As a result of adding `::` for enums, we can then remove the requirement to use `&` as a prefix for attribute names.
   * This change may require changes to all of the configuration.  We will try to allow `&` or not, but that may not be possible.
-* Dynamic expansions will change from `%{md5:foo}` to `%md5(foo)`.
-  * The new syntax is much clearer
-  * Expansions such as `%{User-Name}` will still work.  But `%{1+2}` will also work!
-  * `%{foo:-%{bar}}` will be replaced by `%{foo || bar}`, which is clearer and uses less nesting
+* Dynamic expansions have changed from `%{md5:foo}` to `%md5(foo)`.
+  * The new syntax is much clearer, and supports multiple comma-separated arguments: `%function(a, b, c)`
+  * Expansions such as `%{User-Name}` will still work.  We plan on making `%{1+2}` work, too.

 Please be aware that v4 is in "alpha" right now.  If it works, great.
 If it doesn't work, then please return to using v3.
