distributed separately as the "raco-cross" package.

picts containing large bitmaps.

* Typed Racket more consistently refines field types of non-polymorphic
structs.

The Ubuntu PPA is also now updated to v8.2 on all supported releases (groovy no
longer supported):

https://launchpad.net/~plt/+archive/ubuntu/racket

As usual please report bugs here:

Now we just need the Debian ppas to update to 8.2 for x86 and arm. I'm more inclined for arm as building racket on a 64bit distro on a pi 400 hangs the OS.

I don't know what you refer to when you say "Debian ppas", but 8.2 is
available in Debian experimental for amd64, arm64, armhf, i386,
mips64el, mipsel, ppc64el, and s390x

Sorry I have Ubuntu in my head. I didn't find the experimental packages. I'll check again. Many thanks.

So I tried installing racket 8.2 from the experimental repos (downloaded it) and the dependencies (newer version of libc6) will break some things. So install at your own risk. I'll stick with 7.2 for now.

Yes, I should have mentioned those packages only work with a debian
testing/unstable install. I will make backports after the next debian
stable release (hopefully in a few weeks).

No rush! Just thought I'd let people know. Thanks for your work.
