-  because there was something wrong with input data.

-* Removed `RecurrenceIterator` (use Recur\EventIterator instead).
-* Now using php-cs-fixer to automatically enforce and correct CS.
-* #233: The `+00:00` timezone is now recognized as UTC. (@c960657)
-* #237: Added a `destroy()` method to all documents. This method breaks any
-  circular references, allowing PHP to free up memory.
-* #197: Made accessing properties and objects by their name a lot faster. This
-  especially helps objects that have a lot of sub-components or properties,
-  such as large iCalendar objects.
-* #197: The `$children` property on components has been changed from `public`
-  to `protected`. Use the `children()` method instead to get a flat list of
-  objects.
-* #244: The `Float` and `Integer` classes have been renamed to `FloatValue`
-  and `IntegerValue` to allow PHP 7 compatibility.

-  into individual objects (thanks @DominikTo and @armin-hackmann).
-* Added: VFREEBUSY component, which allows easily checking wether timeslots are
-  available.

-  underscores).
-* Added: Also added the 'IGNORE_INVALID_LINES' option, to completely disregard
-  any invalid lines.
-* Fixed: A bug in Windows timezone-id mappings for times created in Greenlands
-  timezone (sorry Greenlanders! I do care!).
-* Fixed: DTEND was not generated correctly for VFREEBUSY reports.
-* Fixed: Parser is at least 25% faster with real-world data.
-
-
-2.0.0 (2012-08-08)
