Description:

Modules, themes and profiles may no longer set core: 9.x in their info.yml files. The correct way to specify core compatibility is with the core_version_requirment key. See the original change record for the core_version_requirement key for allowed values. core: 8.x can still be used for modules that need to specify core compatibility with version before Drupal 8.7.7.
