The Zig language is under very active development. In order to be current,
Ziglings tracks **development** builds of the Zig compiler rather than
versioned **release** builds. The last stable release was `0.9.1`, but Ziglings

as high as that shown in the example version check above.
It is likely that you'll download a build which is _greater_ than the minimum.
