I just nearly finish Ziglings and it's great! Though the skipped exercises around async is confusing as a newcomer. From the Codberg issues and PRs, it seems like perhaps an update is in the works. Otherwise, I learned a lot and would recommend it!
I've been holding off on Zig because it hasn't reached 1.0 milestone, but I'm starting to think that it might be time to start digging in. Is Ziglings kept up with language changes being made in Zig? It would be very frustrating to find that Ziglings is out of sync with the newer version of Zig that you might be using at the time.
