Hello, There are some undocumented changes in hook_node_info(): http://drupal.org/node/64279#comment-143533 The hook returns an array. In 4.7, the array has the key 'base', which is replaced by the key 'module' in head. How should the project.module be updated? function project_node_info() { return array( 'project_project' => array('name' => t('project'), 'base' => 'project_project'), 'project_issue' => array('name' => t('issue'), 'base' => 'project_issue')); } It defines two different node types, and the base is used to call callback functions, for some node types hooks like hook_access(). Thus, project_project_access() and project_issue_access() are called according to the node type. How is this supposed to work in head? Is 'module' the exact equivalent of 'base'?
