Deprecated Features

The features that have been deprecated for this release or that are on a deprecation path appear below. For more deprecations, see Deprecation Notices.

Known and Possible Issues

For a list of known and possible issues, see the Known and Possible Issues sections in the previous 3.4.x release notes:


TetraScience continually monitors and tests the TDP codebase to identify potential security issues. Various security related enhancements were addressed.

Upgrade Considerations

During the upgrade, there might be a brief downtime when users will not be able to access the platform. This includes the TDP user interface and the APIs. After the upgrade is complete, customers should check their pipelines for failures or cancellations and reprocess those if found. Customers should also do a smoke test of their custom configurations to ensure there are no failures.

Post-upgrade, the TetraScience team ensures that the platform infrastructure is working as expected through a combination of manual and automated tests. If any failures are detected, the issues are immediately addressed or the release is rolled back.
