*** Racket 8.0 is here! ***
Racket version 8.0 is now available from
https://racket-lang.org/
Racket 8.0 marks the first release where Racket CS is the default
implementation. Creating, polishing, and adopting Racket CS has been a
4-year effort involving the entire Racket community. At this point,
Racket CS is faster, easier to maintain and develop, and compatible
with existing Racket programs. Racket CS will continue to improve, but
at this point it is ready to be the primary variant of Racket for all
Racketeers. More details about the current state of Racket CS are
available in the recent blog post (https://blog.racket-lang.org/).
Other notable changes:
* Racket CS has better parallel garbage collection, a 10%-30% reduction
in the size of generated code, and various targeted optimizations.
* A rewrite of the test-engine package allows the `#lang` versions of
teaching languages to produce linked test-failure messages.
* The release comes with a new mark-up DSL for composing text to
appear in the REPL (simple-tree-text-markup).
* Redex has an added `define-overriding-judgment` form and improved
error source location reporting.
* Windows scrolling speed reflects the system preference.
* The db package uses the utf8mb4 charset for MySQL connections.

Are there no 32-bit intel binaries available?

The Linux one that was on everybody's PC before PC's went 64-bit.

I still use that old computer now and then with a stable
Devuan release, especially when I'm on the move.
(though normally at home I have a 64-bit one).

I think your 32-bit options at this point are these:
1) Use one of the nightly builds, e.g. https://plt.cs.northwestern.edu/snapshots/
2) Compile it yourself, using the source bundle.
3) (Of course, you could use an older version. Looks ilke 7.3 is the last one released in a 32-bit Linux build.)
Let me know if I’ve forgotten any other options!

It looks as if there's no Racket on Chez for 32-bit Linux, though there does

Due to changes in how the new CS compiler works, some files have been
moved between the three .deb packages that are in the distribution.
(details: pre-compiled .zo and .dep files are now in the architecture
dependent "racket" package instead of the "racket-common" package)
There might be a higher chance than usual of breakage because of the
major version change. Please do report any packaging bugs on github:

I've added 32-bit i386 Linux CS to the set of snapshots at Utah:

A 32-bit Linux build makes sense as part of the snapshot service, since
part of the job of the service is to make sure things keep working on
various platforms.

fix the packages later by adjusting the dependency flags.
In the meantime, if you get an error on upgrade you should be able to
work around it by just uninstalling the racket packages and
re-installing the latest ones.

version 8.0+ppa1-6 of the package. If anyone still has any upgrade
issues with this version please let me know (you can comment on the
github issue https://github.com/takikawa/racket-ppa/issues/10).
