name: (dev) Zig version update
about: The process we follow to perform a Zig version update
title: 'all: nominate Zig YYYY.MM'
labels: all, zig-update
assignees: 'slimsag'

---

Periodically we [nominate a new Zig nightly version](https://machengine.org/about/nominated-zig) to be the version that Mach targets, and begin the meticulous process of updating every Mach project to use that new version.

This is the tracking issue to do that for the next scheduled nomination (see the date in the issue title.)

You may have been linked to this issue because you sent a pull request to update a Mach project to use a new Zig API - if that is the case we do appreciate the PR and will look at merging it once this process begins. In the meantime, your PR may stay open for a while. You can either use a fork of the project, or [use the version of Zig that Mach currently supports.](https://machengine.org/about/zig-version)

## Update process

* [ ] It is time to begin (see date in issue title, we aim to begin this checklist between the 1st-4th of that month.)
* [ ] The [_Nomination history_](https://machengine.org/about/nominated-zig/#nomination-history) has a new section for the latest nightly Zig version at [ziglang.org/download](https://ziglang.org/download/), with a warning at the top `**IN-PROGRESS:** This version is currently being nominated, see [the tracking issue](https://github.com/hexops/mach/issues/1135) for details. Once everything looks good, the new Zig version is confirmed to be working with Mach, we will declare success, close the issue, and remove this in-progress warning.`.
* [ ] #general Discord message: `Beginning the process of nominating a new Zig version! (you should wait to upgrade until we've updated everything to confirm it works) $GITHUB_ISSUE`
