Hi I would like to finally get into zig, and the new io interface and juicy main delivered in 0.16 seem to be a great momento to jump into the languaje. Can you update the buildpack for zig 0.16.0 for the shell challenge?

Hey @elpablete, we’ve upgraded the supported Zig version to v0.16 for the Shell challenge. You can restart the challenge to start using it.
