Racket v7.9
* Racket CS may become the default Racket implementation in the next
release. If, between this release and the next, no bugs are discovered
in Racket CS that are more serious than those typically discovered in
Racket BC, then Racket CS will become the default for the next
release. (Serious Racket CS bugs were found since the v7.8 release,
but they're ever fewer and farther between.)
* Various improvements to Check Syntax arrows and
renaming, thanks to Sorawee Porncharoenwase
* Full support for struct type properties in Typed Racket, developed by
Fred Fu.
* Racket CS now supports parallel garbage collection, along with
improvements for place-local-allocation and incremental promotion.
* Unix platforms now use the XDG filesystem conventions for the
locations of per-user configuration and library files by default, but
legacy paths are still used where they exist already.
* Scribble improvements by Sorawee Porncharoenwase, William Bowman, and
Shu-Hung You.
* Improvements to the plot library from Alex Harsányi and Bert De
Ketelaere.
* The `datum` form from `syntax/datum` works with syntax pattern
variables and `syntax-parse` attributes.
* Unicode input works with recent versions of libedit in addition
to libreadline. On Mac OS, a compatible version of libedit is
included with Racket.
