Re: [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.

I don't think the one new combinator we have is really going to have that big of an impact on our programmers (and partly because I think we don't really have the right answer yet for how to fit things into Racket & Typed Racket properly).

Re: [racket-dev] release blurb for 5.1.1
The new `racket/syntax' library contains facilities useful for writing macros. The `syntax/srcloc' and `syntx/location' libraries have been added for manipulating source locations. The new `ffi/file' library is useful for writing foreign library bindings that cooperate with Racket's security guard mechanism.

Re: [racket-dev] release blurb for 5.1.1
Here's what I have: - Single-precision floating-point number support is now enabled by default. Single-precision floats now print differently from their default double-precision counterparts, primitives to convert between or distinguish the two have been added, and reader syntax for single-precision specials is now available. - Typed Racket's numeric tower has been entirely overhauled. Typed Racket programs can now use more precise types than before, and check more numeric properties, such as sign or range properties. - Typed Racket's fixnum optimizations have been improved and should apply more broadly. - The performance of Typed Racket's typechecker has been improved. In particular, dispatch on large union types should typecheck much faster than before. - Scribble now supports figures with "here" placement for LaTeX output.
