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.<br><br></i><i>1. (<a href="http://drupal.org/node/839524">issue</a>) </i>Several Search APIs changed: <ul style="margin-left: 40px;"><li>search_data() return value has changed to be a renderable array rather than rendered HTML</li>
<li>
hook_search_page() return value has changed to be a renderable array rather than rendered HTML</li><li>theme('search_result') and theme('search_results') and their
templates/processing functions now use a 'module' argument/variable in
place of 'type'</li></ul>2. (<a href="http://drupal.org/node/885000">issue</a>) drupal_placeholder() now takes a string as an argument instead of an array.<br><br>Thanks,<br>-Randy<br>
