(dev) Zig version update	The process we follow to perform a Zig version update	all: nominate Zig YYYY.MM		slimsag

Periodically we nominate a new Zig nightly version 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.

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 has a new section for the latest nightly Zig version at ziglang.org/download.
