Sorry for the delay this time.
There was an issue with the v8.0 package in which package install would
print an error sometimes. This should be fixed in this release.
If you encounter that or other packaging bugs, please report here:

How can I run Racket 8.1 on Android? I'd love to run DrRacket natively and/or run raco under Termux. Where can I find out more information? Thanks, _Greg

Hi Greg,
I can run Racket on my Android phone via https://github.com/t184256/nix-on-droid , but last time I tried I couldn't get raco to work because of some weird file paths in Android/Termux.
I have never tried running DrRacket though.
