    * Syntax changes
       * The self type parameter in traits is now spelled `Self`
       * The `self` parameter in trait and impl methods must now be explicitly
         named (for example: `fn f(&self) { }`). Implicit self is deprecated.
+      * Static methods no longer require the `static` keyword and instead
+        are distinguished by the lack of a `self` parameter
       * Replaced the `Durable` trait with the `'static` lifetime
       * The old closure type syntax with the trailing sigil has been
         removed in favor of the more consistent leading sigil
