use_spin feature requires nightly. Is this intentional?

[dylanede]

The readme suggests that the use_spin feature does not require nightly, however it enables the nightly feature of spinning_top, which means that it relies on nightly and the const_fn rustc unstable feature. Is this an error in the readme, or in the enabling of the nightly feature on spinning_top?

Thanks for reporting! This is not intentional, seems like we forgot to check this in our CI. I'll look into it.
