Hi @wills4, There is no specific documentation available about HFIX-C4306 but you can obtain detailed information about specific hotfixes by opening a Support Request (SR) with Pega. 

Access My Support Portal: Go to the My Support Portal on PDN

Create a New Request: Click on the orange button that says 'Create'.

Select Request Type: In the 'Request Type' dropdown list, select 'Existing Hotfix Request'.

Enter Hotfix ID: Enter the HFIX-C4306 in the 'Requested Hotfix ID' field.

Verify Product and Version: Ensure that the Product and Version you select match the Product and Version the hotfix was built for. If there is a mismatch, the system will return an error and you won't be able to submit the request until this is resolved.

Fill in the Details: Complete the rest of the fields with the necessary information.
