+* TimeWithZone#marshal_load does zone lookup via Time.get_zone, so that tzinfo/Olson identifiers are handled [Geoff Buesing]
+
 * Time.zone= accepts TZInfo::Timezone instances and Olson identifiers; wraps result in TimeZone instance [Geoff Buesing] 
 
 * TimeWithZone time conversions don't need to be wrapped in TimeOrDateTime, because TZInfo does this internally [Geoff Buesing]
