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