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 won't be able to access the TDP user interface and APIs. After the upgrade is complete, customers should check their pipelines for failures or cancellations and reprocess those pipelines if any are found. Customers should also do a smoke test of their configuration settings to make sure that there are no failures.

After the upgrade, the TetraScience team verifies 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.

For more information about the release schedule, including the GxP release schedule and timelines, see the Product Release Schedule.

For more details about the timing of the upgrade, customers should contact their customer success manager.
