ACM can manage the lifecycle of + rApps made up of an arbitrary number of microservices and rules/learning models/schemas in the form of metadata. In the London release, + the state machine is improved to allow priming of rApp types, and to support deploymeent/undeployment and locking/unlocking of rApps. + Update of the properties of rApps is also supported at run time. In addition, + `ITU Recommendation X.731 <https://www.itu.int/rec/T-REC-X.731-199201-I/en>`_ is now supported for state reporting from rApp microservices. + + See: + - `POLICY-4401 <https://jira.onap.org/browse/POLICY-4401>`_ - R12: Improvements specific to clamp + +* Improved database support in CLAMP ACM + + CLAMP ACM now supports MySql 8.x as a database and supports secured DB communication. + + See: + - `POLICY-4395 <https://jira.onap.org/browse/POLICY-4395>`_ - R12: Database related issues + +* Metadata driven API Generation + + Up until now, the Policy Framework components used handwritten code to implement their REST interfaces and the Swagger 2 API documentation was generated from + annotations in the code. From the London release on, the REST API code is generated from OpenAPI 3.0 (Swagger 3.0) documents. In addition, the API documentation + is substantially enhanced.

In addition to gathering metrics on REST call + performance and policy deployment and execution time, we have defined SLA values for these metrics. We have implemented automated tests that run + as part of the CSIT testing that ensure the SLAs are complied with. + + See: + - `POLICY-4124 <https://jira.onap.org/browse/POLICY-4124>`_ - R12: Add metrics to measure SLAs + +* Improved Testing + + Testing is much improved in the London release. + -
