V653 - V703

A new entry is added each week, and contains the release notes for all of the Tonic versions that were released during that week.

Releases V684 through V695 were removed from quay because of a regression that was fixed in later releases.

V692 - V703

February 3, 2023

Update to PII detection - PII container removed

As of V697, updated how Tonic performs PII detection. The name detection process now also scans for international names with origins from 103 different countries.

The PII detection process now runs from the Tonic worker instead of in a separate container.

To avoid errors when you upgrade, future versions up to V999 will have a placeholder PII container. The container is not active and is not used to run Tonic.

Before you upgrade to V1000 or later, you must remove the PII container from your instance. To remove the container:

  • For a Docker deployment, in docker-compose.yaml, remove the tonic_pii_detection section. You can see the relevant section in this pull request that removed the section from the file that we distribute.

  • For a Kubernetes deployment:

    • Remove the file tonic-pii-detection-deployment.yaml.

    • Remove the file tonic-pii-detection-service.yaml.

    • Update tonic-worker-deployment.yaml to remove the entry for TONIC_PII_DETECTION_URL.

    • Update values.sample.yaml to remove the entry for pii_detection.

You can see the updates in this pull request that made the updates to the files that we distribute.

If you do not remove the PII container before you upgrade to V1000 or later, then when you upgrade Tonic, you will encounter image pull errors.
