rustup is outdated!
To avoid broken installations, as soon as possible please run:
brew upgrade
Or, if you're OK with a less reliable fix: brew upgrade rustup

Not sure why the warning has appeared now.

I do not think we are using rustup, at least as far as I recall. This may be an issue with the GitHub runner default installed packages. We should check to see if an update to the runner image fixes it, in which case we can avoid adding it as a dependency in our build scripts.

closing as we do not use rustup directly.

[jhlegarreta]

I'm fine with closing this, but CIs still show dozens of warnings related to this, so if this is not the right solution we should come up with something else.

[hjmjohnson]

@jhlegarreta It looks like you deleted the branch, so the issue can not be re-opened.

[jhlegarreta]

@hjmjohnson Re-opened.

[thewtex]

This should not hurt, so merging.
