Racket v7.8
* Racket CS may become the default Racket implementation in the next
release. With the improvements in this release, Racket CS provides all
of the functionality of Racket BC (the current default
implementation). 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.
* Racket CS supports AArch32 and AArch64, including places and
futures. The implementation should be considered experimental in this
initial release.
* Racket CS supports an "incremental" garbage-collection mode that can
eliminate long GC pauses for some applications, such as animations and
interactive games.
* Racket CS unboxes local floating-point arithmetic (like Racket BC).
* DrRacket's spell check features lower overhead and has fewer bugs.
* Web Server performance under high concurrency is [better by up to an
order of magnitude](https://github.com/racket/web-server/pull/94/).
The Web Server is also more resistant to clients attempting to use
unconstrained resources.
* The math library includes the Kronecker product.
* Windows supports finer granularity for `sleep` when sleeping for short
periods of time, improving performance in animation.
* The new prop:struct-field-info property provides static information
about field names.
* Debugging context in Racket CS is limited to 64,000 frames
(approximately the same as Racket BC). This reduces the time taken to
handle out-of-memory failures.
* In `plot`, the legend font and the plot font can be controlled
independently, and error-bars have an `#:invert?` option.
* The plot and math libraries have new maintainers: Alex Harsányi for
plot and Pavel Pancheka and Jens Axel Søgaard for math.
