Which release do I choose? Security coverage information

• Sites on 9.4.x or earlier should update immediately to Drupal 9.4.14 instead of this release, but update to 9.5 or higher soon.

Important update information

Changes to site-owner-managed files

• Following this release, Drupal will block access to private files at certain specially crafted paths. Previous versions of Drupal allowed access to these paths, and in most cases blocking access is the correct behavior.

  There may be some sites that rely on allowing access to these paths, or the changes in this release may cause other problems with file access. These sites can add the following line to settings.php:

  $settings['file_sa_core_2023_005_schemes'] = ['private'];
  

  This will preserve the old behavior for files saved in the private files directory, using the private stream wrapper from Drupal core. Sites that need to preserve the old behavior for files using other stream wrappers, from contributed or custom modules, should list those stream wrappers instead of 'private'.

  The comments in default.settings.php have additional information.

  Using this setting will bypass the access checks added in this release, which may allow public access to files that are meant to be private. This setting is a temporary backward-compatibility layer for misconfigured sites. It will be removed in a future release since it is insecure.
