Hi Ricky,

Thanks for your question.  The fix will be to include deleted
instances of recurring events in the feed when an updated-min
parameter is present.  It will also remove the EXDATE syntax from
recurring events.  These changes should take effect for all events,
regardless of when they are created.

Cheers,

-Ryan
