       * Pattern matching over vectors improved and expanded
       * Typechecking of closure types has been overhauled to
         improve inference and eliminate unsoundness
-      * Macros leave scope at the end of modules, unless that module is
-        tagged with #[macro_escape]
 
    * Libraries
