sabre/vobject 4 released

We just released sabre/vobject 4. This is a new major version, and comes with a number of new features and also BC breaking changes. The API is largely the same, but there are a few subtle differences.

New feature highlights

• Support for PHP 7.
• Requires PHP 5.5.
• Support for xCal and xCard, which are XML representations of iCalendar and vCard.
• Added a 'BirthdayCalendarGenerator'. Give it a list of vCards, and it will create an iCalendar object with birthdays.
• Lots of speed and memory improvements.
• Support for the new VAVAILABILITY iCalendar component.
• Added a command-line utility to merge duplicate vcards.
• Using DateTimeImmutable everywhere we used DateTime.
• Denial of service-protection in the RecurrenceIterator.
• Better RDATE support.

The full changelog can be found on Github
