     * Rust now works on 64-bit Windows.
 
   * Language
-    * A new slicing syntax (e.g. `[0..4]`) has been introduced behind
-      the 'slicing_syntax' feature gate, and can be overloaded with
-      the `Slice` or `SliceMut` traits.
     * Indexing can be overloaded with the `Index` and `IndexMut`
       traits.
     * The `if let` construct takes a branch only if the `let` pattern
       matches, currently behind the 'if_let' feature gate.
-    * `let` and `match` bindings and argument names in macros are now
-      hygienic.
+    * 'where clauses', a more flexible syntax for specifying trait
+      bounds that is more aesthetic, have been added for traits and
+      free functions. Where clauses will in the future make it
+      possible to constrain associated types, which would be
+      impossible with the existing syntax.
+    * A new slicing syntax (e.g. `[0..4]`) has been introduced behind
+      the 'slicing_syntax' feature gate, and can be overloaded with
+      the `AsSlice` or `AsSliceMut` traits.
+    * The syntax for matching of sub-slices has been changed to use a
+      postfix `..` instead of prefix (.e.g. `[a, b, c..]`), for
+      consistency with other uses of `..` and to future-proof
+      potential additional uses of the syntax.
+    * The syntax for matching inclusive ranges in patterns has changed
+      from `0..3` to `0...4` to be consistent with the exclusive range
+      syntax for slicing.
+    * Matching of sub-slices in non-tail positions (e.g.  `[a.., b,
+      c]`) has been put behind the 'advanced_slice_patterns' feature
+      gate and may be removed in the future.
+    * Components of tuples and tuple structs can be extracted using
+      the `value.0` syntax, currently behind the `tuple_indexing`
+      feature gate.
     * The `#[crate_id]` attribute is no longer supported; versioning
       is handled by the package manager.
-    * Mutation and assignment is no longer allowed in pattern guards.
-    * Generic structs and enums can now have trait bounds.
-    * `use foo = bar` is now written `use bar as foo`.
+    * Renaming crate imports are now written `extern crate foo as bar`
+      instead of `extern crate bar = foo`.
+    * Renaming use statements are now written `use foo as bar` instead
+      of `use bar = foo`.
+    * `let` and `match` bindings and argument names in macros are now
+      hygienic.
     * The new, more efficient, closure types ('unboxed closures') have
       been added under a feature gate, 'unboxed_closures'. These will
       soon replace the existing closure types, once higher-ranked
       trait lifetimes are added to the language.
+    * `move` has been added as a keyword, for indicating closures
+      that capture by value.
+    * Mutation and assignment is no longer allowed in pattern guards.
+    * Generic structs and enums can now have trait bounds.
     * The `Share` trait is now called `Sync` to free up the term
       'shared' to refer to 'shared reference' (the default reference

   * Libraries
     * Library documentation has been improved for a number of modules.
