[racket-dev] release blurb for 5.1.1

 * 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.

That was in v5.1.
