Breaking changes in 1.0.0

1. Promise instead of callback.

Before 1.0.0 callback function was used to handle the result of modal dialog:

swal(
  {title: 'Are you sure?', showCancelButton: true}, 
  function(isConfirm) {
    ...
  }
);

Starting with v1.0.0 promise should be used instead of the callback:

swal({title: 'Are you sure?', showCancelButton: true}).then(
  function(isConfirm) {
    ...
  }
);

isConfirm is:

• true for confirm button
• false for calcel button
• undefined for outside click or if modal was closed by timer

2. IE is not supported by default

To enable IE10+ support, include es6-promise:

<script src="bower_components/es6-promise/promise.min.js"></script>
