Alexander Kiryuhin announced the 2020.12 Rakudo Compiler Release of the Raku Programming Language. JJ Merelo made sure there’s an up-to-date Alpine-Linux docker image, as well as a raku-test image. And Claudio Ramirez made sure there are Rakudo compiler packages for many Linux distributions. Kudos to all involved!
In related joyous news, Jonathan Worthington released a new version of the Comma Complete IDE (the paid version for subscribers only). The free Comma Community IDE version will be released in January 2021.
