Important: #83724 - API and behavior change in request handler classes

See Issue #83724

Description

In preparation for a better PSR-7 and a new PSR-15 integration the internal request handler classes have been changed:

  • All methods gained strict argument type and return type declarations.
  • Instead of calling HttpUtility::redirect() a RedirectResponse is returned.
  • Instead of returning null a NullResponse is returned.

Impact

Extending one of the core request handlers without adding type declarations (to overloaded methods), will trigger a PHP fatal error.

Affected Installations

All 3rd party extensions extending one of the core request handlers.
