>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #3134576. --> Reported by: [wrd](https://www.drupal.org/user/670860) >>> <p>While the main drd module's info.yml file has been updated to include the core_version_requirement for D9 compatibility, the various submodules included with it have not.</p> <p>This may be intentional -- perhaps they still need to be updated. I'm not sure how to tell. But in case it was merely an oversight, this patch adds the key to each of the six info.yml files so that the module doesn't (hopefully) cause the module administration page to whitescreen. </p>
