-      * Remove `static` keyword
-      * Static method syntax
-      * `as Trait`

    * 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
       * `super` is a keyword, and may be prefixed to paths
       * Trait bounds are separated with `+` instead of whitespace
       * Traits are implemented with `impl Trait for Type`
         instead of `impl Type: Trait`
+      * Lifetime syntax is now `&'l foo` instead of `&l/foo`
       * The `export` keyword has finally been removed
       * The `move` keyword has been removed (see "Semantic changes")

       * Pattern matching over vectors improved and expanded
       * `const` renamed to `static` to correspond to lifetime name,
         and make room for future `static mut` unsafe mutable globals.

+      * Replaced `#[deriving_eq]` with `#[deriving(Eq)]`, etc.
       * `Clone` implementations can be automatically generated with
         `#[deriving(Clone)]`
+      * Casts to traits must use a pointer sigil, e.g. `@foo as @Bar`

       * Method visibility is inherited from the implementation declaration
