    * ??? changes, numerous bugfixes
 
    * Syntax changes
-      * `#[deriving(Encodable)]`, `#[deriving(Decodable)]`
+      * `use mod` is no longer valid.
+      * `fail!` and `assert!` accept `~str`, `&'static str` or `fmt!`-style
+        argument list.
+      * `Encodable`, `Decodable`, `TotalOrd`, `TotalEq`, `DeepClone` can all
+        be automatically derived with `#[deriving(...)]`.
+      * The `Durable` trait is replaced with the `'static` bounds.
+      * At long last, 'argument modes' no longer exist.
+      * The `bytes!` macro returns a vector of bytes for string, u8, char,
+        and unsuffixed integer literals.
 
    * Semantic changes
+      * The borrow checker has been rewritten with flow-sensitivity, fixing
+        many bugs and inconveniences.
       * The `self` parameter no longer implicitly means `&'self self`,
         and can be explicitly marked with a lifetime.
       * Structs with the `#[packed]` attribute have byte alignment and
         no padding between fields.
+      * The `for` loop protocol now requires `for`-iterators to return `bool`
+        so they compose better.
+      * `Option<~T>` is now represented as a nullable pointer.
+      * `@mut` does dynamic borrow checks correctly.
+      * Macros TODO
+      * The `main` function is only detected at the topmost level of the crate.
+        The `#[main]` attribute is still valid anywhere.
+      * Struct fields may no longer be mutable. Use inherited mutability.
+      * The `#[non_owned]` attribute makes a type that would otherwise be
+        `Owned`, not. TODO this may change to non_send before 0.7
+      * The `#[mutable]` attribute makes a type that would otherwise be
+        `Const`, note. TODO this may change to non_freeze before 0.7
+      * Unbounded recursion will abort the process after reaching the limit
+        specified by the `RUST_MAX_STACK` environment variable.
+      * The `vecs_implicitly_copyable` lint mode has been removed. Vectors
+        are never implicitly copyable.
 
    * Libraries

       * std: `path` type renamed to `Path`.
       * std: Many standalone functions removed in favor of methods in
-        `vec`, `str`, TODO. In the future methods will also work as functions.
+        `vec`, `str`. In the future methods will also work as functions.
