Read this summary of the new features, changes, and updated information for your product from Xanadu to Yokohama. Tip: If there were no updates for a release notes section in a certain family release, we included a short note for your reference. For example, if a product did not have any updates in Tokyo, the row says "No updates for this release." ## Important information for upgrading Flows, subflows, and actions in Workflow Studio to Yokohama Before you upgrade to Yokohama, review these pre- and post-upgrade tasks and complete the tasks as needed. {#dfrn3-flowssubflowsandactionsinworkflowstudio-summary__entry__2} | Release | Release notes | |-|-| | Xanadu | After upgrading, users who previously had the fd_read_operations role will now see only basic execution details such as the run state and duration. This restriction prevents users with this role from seeing sensitive information in execution details. To provide read access to all execution details such as input configuration and runtime values, grant the user the new role fd_read_operations_all. | | Yokohama | No updates for this release. | [ ] ## New features Between your current release family and Yokohama, new features were introduced for Flows, subflows, and actions in Workflow Studio. {#dfrn3-flowssubflowsandactionsinworkflowstudio-summary__entry__8} | Release | Release notes | |-|-| | Xanadu | **[Xanadu Patch 3](https://www.servicenow.com/docs/access?context=xanadu-patch-3&family=xanadu&ft:locale=en-US)** [Generate data pill values during flow generation](https://www.servicenow.com/docs/access?context=flow-generation&family=xanadu&ft:locale=en-US) : Generate appropriate data pill values for supported flow triggers and action inputs.
