 * 1.8.0 (2012-XX-XX)
 
+ * simplified usage of the autoescape tag; the only argument is now the escaping strategy or false (with a BC layer)
  * added a way to dynamically change the auto-escaping strategy according to the template "filename"
  * changed the autoescape option to also accept a supported escaping strategy (for BC, true is equivalent to html)
  * added an embed tag

 When automatic escaping is enabled everything is escaped by default except for
 values explicitly marked as safe. Those can be marked in the template by using
 the :doc:`raw<../filters/raw>` filter:
