  var addMonths = require("date-fns/src/add_months");
  
  // v1.0.0 onward
  var addMonths = require("date-fns/add_months");
  

• BREAKING: functions that had the last optional argument weekStartsAt (i.e. endOfWeek, isSameWeek, lastDayOfWeek, setDay, startOfWeek) now instead receive the object options with the property options.weekStartsOn as the last argument.

  // Before v1.0.0
  var result = endOfWeek(new Date(2014, 8, 2), 1);
  
  // v1.0.0 onward
  var result = endOfWeek(new Date(2014, 8, 2), { weekStartsOn: 1 });
  

• BREAKING: remove the function getTimeSinceMidnight that was used inside the other functions.
