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. Sites such as raku.land and the IRC logs server beta run Cro in production. Check out all the fixes, improvements and new features such as async reverse proxying and improved warnings from rendering templates with undefined values.
Generating a lot of frames
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!
Daniel Sockwell has written two updates on the progress of the Persistent Data Structures Grant.
Data::Record’s Identity Crisis
That time of the year is coming closer!
Only a few weeks to go, and it’s Advent Calendar time again! Make sure you get a slot in this year’s Advent Calendar for the Raku Programming Language, by adding your blog post proposal to the preliminary list of authors and articles!
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!

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!
