4.2.7-rc1

(fix): When leveraging the include_union_utils configuration flag, the Pydantic models will no longer include transitive dependencies within update_forward_ref calls, since these should not be necessary. This effectively scopes back the changes introduced in 4.0.0-rc5, which included changes to improve circular reference handling in Pydantic models.

4.2.7-rc0

(fix): Dynamic header suppliers, as used within the OAuth provider are now invoked on every request, not just the first. This was a regression introduced within an earlier version that is now fixed. As a results of this fix, the refresh_token is now correctly refreshed.
