Support Lifecycle Policy

Please be aware of the following constraints regarding legacy software:

  • The 3-Year Rule: As stated in Article 6 of the EULA, Astah discontinues technical support and download availability for any version three years after the release date of its first decimal-place version (e.g., v10.0, v10.1).

  • Security & Compatibility: Versions older than three years are no longer maintained. We strongly recommend using the latest version available on our website to ensure peak performance and security.
