2.1.1

• Fixed: Issue #50. RecurrenceIterator gives incorrect result when exception
  events are out of order in the iCalendar file.
• Fixed: Issue #48. Overridden events in the recurrence iterator that were past
  the UNTIL date were ignored.

2.1.0

• This version is fully backwards compatible with 2.0.*. However, it contains a
  few new API's that mimic the VObject 3 API. This allows it to be used a
  'bridge' version. Specifically, this new version exists so SabreDAV 1.7 and
  1.8 can run with both the 2 and 3 versions of this library.

• Added: Property\MultiDateTime::hasTime().
• Added: Property::getValue().

  class names, so they are actually overridable.
