In Frankfurt, the policy framework finished its support of TOSCA Compliant Policy Types. New Policy Types were implemented to support these domains:

• Control Loop Operations
• Control Loop Guard Queries
• OOF Project Optimization placement
• SDNC Naming Algorithms

Native Policy Support for each PDP was implemented. Now users can use the APIs to create policies specific to a PDP such as Drools Rules, XACML XML policies and Apex policies.

• Drools Native DRL
• XACML Native XML
• Apex Native Javascript

Consolidated the health check of all the components into the PAP. Previously each component had to be queried for health status, now a single call to the PAP can retrieve the health of all the components. NOTE: This does not include legacy components.

• Statistics for XACML and Apex PDP components enhanced.

Control Loop actor code was re-designed and cleaned up enabled faster integration of new actors and operations for control loops.

Drools Rules Simplification.

• A new API is introduced to deploy policies on specific PDPGroups
• Fetch policy deployment status: Clients will be able to poll the PAP API to find out when policies have been successfully or unsuccessfully deployed to the PDP's.

• Decision API for monitoring policies was enhanced to support an abbreviated list of policies.
• Decision API now supports naming policies for CCSDK project.
• Decision API now supports a closest match algorithm for optimization policies and enhancements were made to better support policies with "matchable" properties.
• Support for PASSIVE Mode
• Now returns error when a policy cannot be loaded

• Support for offline mode which allows users to run drools in a locked environment.
• Parameterize mvn repo urls and proxy settings which allows the users to build the docker images for drools-pdp and drools-application using their own CI pipelines.
• New Controller TOSCA Compliant Operational Policies.
• New Controller TOSCA Compliant Native Controller and Artifact Policies.
• Enhanced Telemetry API to support Native and Controller TOSCA Policy Types.
• Validation of Operational and Native Policies against their policy type.
• Rate limiting of ONSET events to prevent flooding from identical events from DCAE.
• Docker for a generic Drools-PDP standalone that can be used for other applications.

• Multiple Policy Deployment now supported
• Apex now sends the Statistics data in every heartbeat sent to PAP
• Changed JavaScript executor from Nashorn to Rhino as part of Java 11 upgrade.
• Passing parameters from ApexConfig to policy logic.
• Added support for interaction with CDS over gRPC

• Added a new simplified API to create one or more policies in a single API call.

• 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.
