The Cro Development team proudly announced version 0.8.7 of Cro, the set of Raku libraries for building reactive distributed systems, lovingly crafted to take advantage of all Raku has to offer.

Binary Regexes

Matthew ‘Stephen’ Stuckwisch was triggered by a question on StackOverflow, to revisit their ideas of what would be needed to allow regexes to be applied to binary data. Which resulted in quite a lot of useful links and discussion!

Grant Update

Weeklies

Weekly Challenge #139 is available for your perusal.

A new release manager, please

The Rakudo Team is still looking for someone willing and able to take on the role of the release manager of the upcoming MoarVM, NQP and Rakudo releases. You don’t have to be an ace programmer, or have intimate knowledge of the code base. The only thing you need is some time, and maybe some hardware to run tests, and be able to follow the Release Guide.

If you are interested in doing this responsible job, please make yourself known on the #raku-dev channel on Libera.chat. Your efforts will be greatly appreciated!

Updated Raku Modules

Winding down

A little bit of a quiet week, it feels, with only a single new module. But still nice to see that at least 13 people have released updated modules, one of them the new version of Cro! And again a thought provoking discussion this week. Check again next week for more Rakudo news. And it can’t be said enough: stay healthy and stay safe. See you then!
