+       * src/summaryview.c
+               - Set sensitivity of delete actions
+               - Added function check_permission() that will check if the
+                 user is authorized to delete a message. For news, it
+                 will check if the author is the same.
+               - Enabled deletion when there is no trash folder.
+
+       * src/news.[ch]
+               - Added news_cancel_article() to cancel articles
+               - Implemented news_remove_message() (public function)
