Sandra,

We strongly recommend updating to the latest version. That is no longer supported–meaning, validation results **will vary greatly** from newer versions and also from what agency reviewers may see in their results. Use at your own risk.

We know that v2.2.0 is not supported since 31-Mar-2021 but can we check that this version will remain accessible on the long term?
