+	* icalproperty.c.in Improved icalproperty_as_ical_string() to
+ 	eliminate the possibility of having a VALUE parameter that does
+ 	not match the actual kind of value.
+
+	* icalvalue.c.in made icalvalue_*_trigger() and
+ 	icalvalue_*_datetimeperiod non-autogenerated. These routines were
+ 	for combined value type -- non standard values that can have more
+ 	than on standard value type. These non-standard types now delegate
+ 	to stadard types.
