Error updating to 0.26 - trait bound `std::iter::FusedIterator` is not satisfied

While updating to 0.26, we get the following new error message:

error[E0277]: the trait bound `arch::x86_64::RegsIter: std::iter::FusedIterator` is not satisfied

Could this be related to #311 ? Any idea how to approach /debug this?

It was an old version of strum_macros, thanks!
