• The Topic is the topic
• Swarms of Exceptions

Discussions

Alexey Melezhik started up two discussions: one about RakuDist/Whateverable/Alpine and one about black box testing for ake runs.

• Jan-Olof Hendig updated MoarVM to use libuv 1.38.0 and fixed some double frees.
• Christian Bartolomäus fixed the MoarVM build on FreeBSD.

Long time contributor and creator of Panda, Tadeusz Sośnierz, has written a blog post about the LGBT situation in Poland, which really hit home for yours truly. So in closing, one can only say: keep healthy, keep safe and see you next week for yet another instalment of the Rakudo Weekly News!
