Upgrade Status (for Drupal 9)

module_name
upgrade_status
Description

Very useful module for scanning installed modules (including your own custom code) for compatibility issues - gives a detailed report of necessary fixes.

NB: scanning using the UI (rather than Drush) won't work on a dev server without a valid SSL certificate.
