Projects that have deprecation checking results with errors to fix. These could still include parse errors found in the process of deprecation checking, but most of the errors found are real deprecated API uses. We further segment these errors into Drupal and not Drupal deprecated API uses. Most of the Drupal ones are even covered by drupal-rector automation (thanks to Palantir.net funding) to fix them automatically as much as possible. There are also a number of third party API deprecations, some of which we segment out for easier tracking. Use Upgrade Status locally to verify your progress fixing these problems.
Results are from dataset #58581 from 2023-12-03T12:36. Report is ran by the Drupal Association regularly.
