 ## Recent breaking changes
 
-- v4.0.1 renamed the `readonly` prop to `disabled` which now prevents all form or user interaction with this component including opening the dropdown list which was still possible before. See [#45](https://github.com/janosh/svelte-multiselect/issues/45) for details. The associated CSS class applied to the outer `div` was likewise renamed to `div.multiselect.{readonly=>disabled}`.

 - v4.0.3 CSS variables starting with `--sms-input-<attr>` were renamed to just `--sms-<attr>`. E.g. `--sms-input-min-height` is now `--sms-min-height`.
 
-- v5.0.0 Support both simple and object options. Previously string or number options were converted to objects internally and returned by `bind:selected`. Now, if you pass in `string[]`, that's what you'll get from `bind:selected`.
