@PowerKiKi This is in release notes for expressive 3.0.0alpha3 and at this point all was good, check zend-expressive-router:3.0.0alpha1:
https://github.com/zendframework/zend-expressive-router/tree/3.0.0alpha1/src

[PowerKiKi]

This is no longer correct in alpha3, exactly since zendframework/zend-expressive-router@84a0f54#diff-25d902c24283ab8cfbac54dfa101ad31. I think doc should be kept up to date as much as possible.

@PowerKiKi still I think it's changelog and at time of this release all was fine, this is not a migration guide so we shouldn't change changelog as it was correct and became incorrect because one of dependencies changed.

@PowerKiKi — @webimpress is correct. The changelog entry is correct for the release in which it was made.

When I prepare the final 3.0.0 changelog, I'll be merging all of the alpha entries, and, at that time, these will be corrected to the final versions.
