    * Libraries
-      * Lots of effort to organize the container API's around `core::container`
-      * `core::send_map` renamed to `core::hashmap`
       * Added big integers to `std::bigint`
       * Removed `core::oldcomm` module
       * Added pipe-based `core::comm` module
-      * Reimplemented `std::treemap`
       * Numeric traits have been reorganized under `core::num`
-      * `core::dvec` removed. Use `@mut ~[T]` or other language types
       * `vec::slice` finally returns a slice
       * `debug!` and friends don't require a format string, e.g. `debug!(Foo)`
+      * Containers reorganized around traits in `core::container`
+      * `core::dvec` removed, `~[T]` is a drop-in replacement
+      * `core::send_map` renamed to `core::hashmap`
+      * `std::treemap` reimplemented as an owned balanced tree
+      * `std::deque` and `std::smallintmap` reimplemented as owned containers
+      * `core::trie` added as a fast ordered map for integer keys
