Hi Gophers!

It's been a while... But we bring you a new GoopherJS release, featuring long-awaited generics support. Thanks to @grantnelson-wf's persistence, GopherJS now fully supports generics according to the Go 1.19 spec. Given the magnitude and complexity of the change, we would like to make this a beta release, if you run into any bugs or issues, please feel free to report them. If no major issues are discovered, we will tag a stable 1.19 release, at last.

In the meantime, work on 1.20 is already starting, stay tuned!
