Output for git.master, git.master_jit, rfc.property-hooks
Deprecated: Return type of MyDOM::saveXML($context = null, $options = 0) should either be compatible with DOMDocument::saveXML(?DOMNode $node = null, int $options = 0): string|false, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /in/iWvBG on line 13
