 * IO::File and IO::Dir will go away, and &dir will return values of type
   IO::Path (which is currently the superclass of IO::File and IO::Dir).
 
+* Leading whitespace in rules and under :sigspace will no longer be
+  converted to <.ws> .  For existing regexes that expect this conversion,
+  add a <?> in front of leading whitespace to make it meta again.
+  Scheduled for the 2012.08 release.

+* The ?-quantifier on captures in regexes currently binds the capture
+  slot to a List containing either zero or one Match objects; i.e., it
+  is equivalent to "** 0..1".  In the future, the ?-quantifier will
+  bind the slot directly to a captured Match or to Nil.  Existing code
+  can manage the transition by changing existing ?-quantifiers to
+  use "** 0..1", which will continue to return a List of matches.

 * The method Str.bytes will be removed. To get the number of codepoints
   in a string, use .codes instead. To get the number of bytes in a
   given encoding, use $str.encode($encoding).bytes .
