- Liam Fallon Fixes for Policy Versioning
- When retrieving a Policy Type, inherited policy types are now included in the API call along with referenced Data Types.
- Pamela Dragosh Configurable Pre-loading and pre-deployment of policies. When ONAP is brought up, the user can configure a set of default policies that can be created and deployed.
- Pamela Dragosh Enhancements to Lifecycle APIs
- Added a new simplified API to create one or more policies in a single API call.
- Ram Krishna Verma James Hahn Treatment of PASSIVE state for PDPs: If a PDP fails to deploy one or more policies specified in a PDP-UPDATE message, PAP will undeploy those policies that failed to deploy to the PDP. This entails removing the policies from the Pdp Group(s), issuing new PDP-UPDATE requests, and updating the notification tracking data.
