MR3 1.0 has been released by DataMonad. The documentation on MR3 is now at MR3docs, and the old site will no longer be updated.
https://www.datamonad.com/ https://mr3docs.datamonad.com/ With the release of MR3 1.0, I have written an article on testing MR3. It's a long article, but could be useful to those interested in trying MR3 in production. https://www.datamonad.com/post/2020-02-19-testing-mr3/ Cheers, --- Sungwoo Park
