* The "DrScheme" application (which simply ran DrRacket in the last few releases) has been removed. The "MrEd" GUI executables for Windows and Mac OS X have also been removed, although the "mred" console executable remains for Unix and Mac OS X to support old scripts.
* The `racket/gui' library now supports multi-column list boxes and scrolling panels. * The new `racket/stream' library provides `stream-first', `stream-rest', a lazy `stream-cons', and so on. Streams are a subtype of sequences, so streams and the `for' forms work together. Some sequence generators, such as `in-range', now produce streams. A `racket/sequence' library replaces the old `racket/stream' library. * JIT improvements include a small change to aid x86 branch prediction on function-call returns, which can speed up some programs significantly.
