Xapp changes) // RIC-796 sub mgr and xapp-frame error cases // RIC-793 Prevent A1 Job ID conflicts from multiple RICs using the same A1 producer (SMO) // Partial only: RIC-647 Reimplement (first step of reimplementation A1 mediator in golang to avoid A1 being the only python container in RIC platform // RIC-709 E2 stats exposing individual counters instead of groups // RIC-714 support for DMS REST interface in addition to DMS CLI // RIC-113 DB: SDL CLI for debugging and testing // RIC-110 FindKeys/GetAllKeys SDL API to support glob-style patterns // RIC-676 Update to Ubuntu 20.04 as base image for all containers // improvements in xApp testing // 29 Epics planned: link and 30 items as stretch goals: link

Achieved E release highlights = high-level release notes (TODO) below (note that the release image list is here (once releases): TODO)

From the 29 epics planned (link) we implemented so far 11 (link). 11 items have been moved out of the E release, e.g, because of implementation delays (link). We expect 6 items to still complete and one item (RIC-375) is still under discussion what to do with it (link).
