2023.17 ReleasePeriod

This week saw a number of remarkable releases: first of all a new version of Rakudo (2023.04), which was released by Justin DeVuyst (with the binary packages for various Linux distributions by Claudio Ramirez, including for the latest Ubuntu and Fedora). This was followed up by the release of Rakudo Star 2023.04 by Anton Oks.

Earlier in the week, Jonathan Worthington released the 2023.04 version of the Comma IDE, the Integrated Development Environment for the Raku Programming Language. A time of harvesting indeed!


The Raku Conference 2023 will be hybrid! To incorporate the positive aspects of online events, you can attend in person in Riga, or online from anywhere on the planet. And there is still time to submit a presentation!

And this just in: specially priced Student in-person tickets!

Fez Outage

While preparing this week’s Rakudo Weekly News, it became clear that there had not been any new modules published since Wed, 19 Apr 2023 17:34:36 GMT. After further investigation, this turned out to have been caused by a silent outage of the fez upload service. It would accept any uploaded distributions without any error message, yet failed to store or index or publish the module. This has now been corrected. But any modules uploaded in this period, sadly will have to be uploaded again.

The good news of this is that no new modules were published using the p6c or CPAN backends in this period, a clear indication that those storage systems for the Raku module ecosystem are being used less and less.
