What’s in this release

  • AccessControl: scope resolver cache is invalidated when a datasource is deleted to prevent stale permission/authorization state.
  • Rendering: Image Renderer now supports custom CA certificates, allowing rendering from endpoints secured with private or internal CAs.
  • Platform: Go toolchain updated to 1.25.8 for build/runtime fixes and dependency updates.

Upgrade notes

  • Migration fix for CollateAlertRuleGroup improves MariaDB compatibility — if you run Grafana with MariaDB, apply the upgrade and check migration logs for any errors.
  • No specific rollback instructions are provided in the release notes; follow your usual rollback procedures if you need to revert.
