Anton Antonov has produced a another nice video with Mondrian paintings, again showing the use of their Raku modules.

London Workshop 2024

The first batch of talks for the London Workshop (on Saturday 26 October) has been accepted. Some of them about Raku. More Raku presentations are most definitely welcome.

Also, rumour has it that Richard Hainsworth is planning on organizing a Raku Developer Summit in Cardiff (only about a 2 hour or so train ride away from London) on the Monday/Tuesday (28/29 October) after that. So remember those dates!

Rakudo Compiler Release

Justin DeVuyst has produced the seventh Rakudo compiler release of 2024: 2024.07, a mostly bug-fixing release. But also 5% faster if running on Intel hardware! Binary packages will become available shortly, as well as updates to Rakudo Star, if they are not already. Kudos to all involved!
