The nextMonth, previousMonth, nextYear, and previousYear instance methods of the Uize.Widget.Calendar class have been killed.

This change is not backwards compatible. In the unlikely event that you would want to programmatically advance the month or year of a Uize.Widget.Calendar instance, you can easily do so by using the set and get instance methods, as in...

myCalendar.nextMonth ()      ->  myCalendar.set ({month:myCalendar.get ('month') + 1})
myCalendar.previousMonth ()  ->  myCalendar.set ({month:myCalendar.get ('month') - 1})
myCalendar.nextYear ()       ->  myCalendar.set ({year:myCalendar.get ('year') + 1})
myCalendar.previousYear ()   ->  myCalendar.set ({year:myCalendar.get ('year') - 1})
