* PHP 8.3 #[\Override] https://php.watch/versions/8.3/override-attr With PHPStan `checkMissingOverrideMethodAttribute` https://phpstan.org/config-reference#checkmissingoverridemethodattribute And modified the call to phpstan-next on the model of https://github.com/FreshRSS/Extensions/pull/228 (more robust than the find method, which gave some strange errors) * Update extension example accordingly
