Thanks, looks great! I've edited your PR title to remove the issue number (as it would distract from the PR number when merged). The PR description mentioning "resolves #nnnn" is perfect and sufficient.

We merge PRs simultaneously to our GitHub and MS-internal repos in a semi-manual process, batched up to save time. Your PR will be part of the next batch, likely next week (depending on how busy I am). I'll post comments here as I prepare your PR for merging.

I'm mirroring this to the MSVC-internal repo - please notify me if any further changes are pushed.

Thanks for updating this version macro, and congratulations on your first microsoft/STL commit! 😻 🎉 🚀
