Instead of updating the releases frequently, does it make sense to have one fixed release and other as 'latest'?

Thank you for adding this workflow! It’s going to be very helpful for our users.

I believe this configuration currently splits the tests alphabetically by default. Would it make sense to add comments or examples showing how to split tests based on file size or previous timing data as well?

I'm curious - does CircleCI handle test splitting by distributing them across multiple separate machines, or are the tests simply divided among different cores on the same machine?

NOTE: CircleCI's free plan doesn't support parallelism for macOS cloud runners. Hence those users won't be able to use test-splitting with the current workflow's mac executor configuration. Decided not to add this info as a comment in our workflow since it will increase maintenance burden.
