I think we should mention the icons, for two reasons: 1. Neil did a ton of work, and it should be recognized. 2.

There's no mention of the new icons at all now (not the library).
Superficial, but will probably make many happy.

It's not clear on a quick glance that this is a TR thing. (Also,
"customize" sounds a little like underselling it, but maybe there's no
good way to talk about what can be done with it.)

"up to 4 times faster" sounds fishy -- I think that just "faster"
sounds better. Also, should move up.

[racket-dev] Release Announcement for v5.2.1, second draft
Below is the second draft of the release announcement items for
v5.2.1. Let me know if I've missed something.
--
* Performance improvements include the use of epoll()/kqueue()
instead of select() for the Racket thread scheduler,
cross-module inlining of small functions, and the use of SSE
instead of x87 for JIT-compiled floating-point operations on
platforms where SSE is always available (including x86_64
platforms). A related change is the interning of literal
numbers, strings, byte strings, characters, and regexps that
appear in code and syntax objects.
* MysterX's ActiveX support is deprecated and will be removed in
the next release. MysterX's core COM functionality will become
deprecated in the next release, but COM functionality will be
supported for the foreseeable future as a compatibility layer
over a forthcoming `ffi/com' library.
* The performance of Redex's matcher has been substantially
improved; depending on the model you should see improvements
between 2x and 50x in the time it takes to reduce terms.
* The `typecheck-fail' form allows macro creators to customize the
error messages that Typed Racket produces. This is especially
useful when creating pattern matching macros.
* The `2htdp/universe' library's `big-bang' form supports an
experimental game pad key handler.
(edu: The handler accepts a limited number of keys, similar to a
game pad; the addition of a game-pad handler also overlays the
attached game pad icon on the big-bang canvas. A compatible
addition will appear in WeScheme.)
* In the DMdA teaching languages, infinite recursive signatures
("streams", for example) with no intervening `mixed' are now
supported, and the signatures of record definitions without fields
now have generators for use with `property'.
* The `db' library now supports nested transactions and PostgreSQL
arrays. Bugs involving MySQL authentication and memory corruption
in the SQLite bindings have been fixed.
* The Macro Stepper tool in DrRacket no longer executes a program
after expanding it.
* Plots look nicer, render up to 4 times faster, and are more
correct at very small and very large scales. New features
include customizable dual axis ticks and transforms (e.g. log
axes, date and currency ticks, axis interval collapse and
stretch), stacked histograms, and 3D vector fields. The legacy
`fit' function and libfit have been removed.

If we're announcing it, this could work: * A new `images' library produces ray-traced icons and logos, and provides macros to embed these and other computed bitmaps into compiled programs. DrRacket is the first major consumer. When I make the rendering API public - which includes the ray tracer, pict-like combiners for two-and-a-half-dimensional bitmaps, and fast image processing primitives, all in Typed Racket - there will be more to say. Do we want to wait to announce `images' until then? I thought it was already public. If not, maybe we should drop this item. Ryan _ Racket Developers list: http://lists.racket-lang.org/dev

[racket-dev] Racket logo: SVG version
I recently searched for a vector or high-resolution raster version of the Racket logo (that would be suitable for print) but did not have any luck. In a 2009 thread on the users mailing list [1], I found that the current logo is rendered using POV-Ray, so a vector format of the logo likely does not exist. I tried recreated the logo myself, and I am attaching the result to this email, in case it may be of use to the Racket team. Note that this SVG 1.1 file makes use of an opacity gradient as well as a blend filter; the result is not rendered consistently across multiple applications. Of the applications that I have tried, it looks fine in InkScape 0.47 but not in Firefox/Aurora 9.0.1 (both on 64-bit Debian Linux).
