 * 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
