Important: #83724 - API and behavior change in request handler classes¶
See Issue #83724
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
- Instead of returning
Extending one of the core request handlers without adding type declarations (to overloaded methods), will trigger a PHP fatal error.
All 3rd party extensions extending one of the core request handlers.
