"The Typed Racket API for fast floating-point bitmaps (flomaps) is now 
public. Image processing operations include pointwise arithmetic, 
gradients, blur, resizing with correct downsampling, arbitrary spatial 
transformations, and pict-like combiners."

The changes to plot are small enough to leave out.

- Optimization Coach (formerly Performance Report) now reports
  information about Racket's inlining optimizations. Optimization Coach
  can be launched in any language through the View menu.

 * Submodules are nested module declarations that can be loaded and run
   independently from the enclosing module. For an overview of
   submodules, see

     http://blog.racket-lang.org/2012/06/submodules.html

 * A new `ffi/com' library replaces MysterX; a compatibility `mysterx'
   library remains, but without ActiveX support. The new
   `ffi/unsafe/com' library offers a more primitive and direct way to
   use COM classes and methods.

>   - new error message convention

 * Most error messages use a new multi-line format that is designed to
   be more consistent, easier to read, and accommodate more
   information.

james:
- added would-be-future (a5676e9a)

Would-be-future is a special type of future that always executes sequentially and records all potential barricades a regular future would encounter.

- added futures visualizer (b6f71ec4)

The futures visualizer is a graphical profiling tool for parallel programs using futures. The tool shows a detailed execution timeline depicting the migration of futures between threads, and gives detailed information about each runtime synchronization that occurred during program execution.

   These are probably not worth including.

Re: Release Announcement for v5.3

If we're going to include the contract related bullets below, then we
should probably mention struct/dc, too. But I think this is too many
bullets for this amount of stuff. How about something like this:

 - the contract library has better support for interfaces, generics,
prompts, continuation-marks, and structs

and then put those bullets, plus a bullet for struct/dc into the
racket HISTORY file (if they're not already there).

That's fine with me.
