We distinguish between 'end of support' and 'end of life':
End of support:
We no longer support the platform version but you can still run your projects. Please be aware that this platform won't receive quality or security updates.
End of life:
you can no longer run the version on our platform
We will notify customers using platforms that are planned for "End of life" ahead of time, with clear instructions of how to avoid any disruption and a reasonable time window to implement any necessary changes.
[Attlaz makes no guarantees of supporting products which have reached their End of Life. Behaviors and APIs relating to End of Life products may be removed entirely. Future releases will not include support for end-of-life features. Platform SLAs do not apply to features that have reached the end of their life.]
