Nightly Changelog

Notable changes:

  • Due to security vulnerabilities and maintainability issues, the S3 service is deprecated in TrueNAS CORE 13.0 and scheduled for removal in CORE 13.1. Beginning in CORE 13.0-U6, the CORE web interface generates an alert when the deprecated service is either actively running or is enabled to start on boot. Users should migrate to a separately maintained MinIO plugin or otherwise move any production data away from the S3 service storage location before upgrading to a 13.1 pre-release version. See the CORE 13.0 tutorial for detailed migration instructions. See also Feature Deprecations.
  • The web UI Shell is removed in CORE 13.1. Users can continue to access the shell using SSH or a local connection.
