PHP 8.0.26 Released!

The ReturnTypeWillChange class

(PHP 8 >= 8.1.0)

Introduction

Most non-final internal methods now require overriding methods to declare a compatible return type, otherwise a deprecated notice is emitted during inheritance validation. In case the return type cannot be declared for an overriding method due to PHP cross-version compatibility concerns, a #[ReturnTypeWillChange] attribute can be added to silence the deprecation notice.
