[development] Drupal 7 API Change notification: Form, File, XMLRPC API changes

[Randy Fay]

*We try to notify this list when API changes are made in Drupal 7, so
contrib and custom developers have a chance to fix their code before they
have the pain of figuring out why it's broken.

*File, Form, and XMLRPC APIs changed recently:


   - (issue <http://drupal.org/node/763376>) If you use*#limit_validation_errors
   * in a multistep form, especially #limit_validation_errors = array(),
   your multistep form may now be broken.
   - (issue <http://drupal.org/node/846296>) If you do *file downloads*,
   there is a new access check regimen to use. hook_file_download_access() and
   hook_file_download_access_alter() have been added.
   - (issue <http://drupal.org/node/353458>) *hook_file_references*() was
   removed, and the entire method of managing references to managed files was
   changed and simplified. The summary is in
   http://drupal.org/node/353458#comment-3193206. If your code implements
   hook_file_references() or otherwise uses managed files, you'll want to take
   a look at this.
   - (issue <http://drupal.org/node/881536>) *xmlrpc*() function was
   changed.  If your module uses xmlrpc(), it's broken until you fix it.
   Upgrade details are at http://drupal.org/update/modules/6/7#xmlrpc

Thanks,

-Randy
