Guide to API changes

Is there a document that details the changes to the API so that I can work out what I need to do or what I need to get a programmer to do to fix Draggable Views since the latest version of Views has broken that module.

The error I get is:

Fatal error: Call to a member function uses_fields() on a non-object in /home/mepppen3/public_html/drupal/sites/all/modules/views/includes/view.inc on line 556

That line is in the middle of this bit of code:

$this->init_style();
if ($this->style_plugin->uses_fields()) {
$this->_build('field');
}

The Views complains of a Missing Style Plugin. I am not a programmer but I can read code and make small changes when required or I can pay for someone to fix it if I have the information on what has changed (I am not sure the developer is around at the moment to fix that module).

Thanks!
