Output for git.master, git.master_jit, rfc.property-hooks
Deprecated: Return type of Test::attach($object, $data = null) should either be compatible with SplObjectStorage::attach(object $object, mixed $info = null): void, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /in/mXdWO on line 8
