Howdy! Similar to [Suibeom’s topic here](https://forum.codecrafters.io/t/zig-minor-version/15427), I’m interested in utilizing some `std.io.Reader` definitions from Zig v0.15.2, although I am working on the shell challenge. Can this be updated?

Related, I noticed that the update for the previously mentioned topic was a PR to the appropriate challenge repo to change the Dockerfile to use the updated version. Is there a preference for how to request the updates, through this forum or the GitHub repo directly? I’m happy to help by making the PR, but I’m not sure of what needs to be tested prior to acceptance.

Howdy @aosterhage, I’ve upgraded the supported Zig version to 0.15.2 for all challenges.

To start using it, make sure to [update the buildpack version](https://forum.codecrafters.io/t/new-feature-update-language-version/15245) in your repo as well.

Feel free to post any further version requests here on the forum!
