 ================================================
 
 O-RAN Alliance (https://www.o-ran.org/) members and contributors have committed to evolving Radio Access Networks (RAN) around the world. Future RANs will be built on a foundation of virtualized network elements, white-box hardware and standardized interfaces that fully embrace O-RAN’s core principles of intelligence and openness. An ecosystem of innovative new products is already emerging that will form the underpinnings of the multi-vendor, interoperable, autonomous RAN, envisioned by many in the past, but only now enabled by the global industry-wide vision, commitment and leadership of O-RAN Alliance members and contributors.

 O-RAN SC is partnering with the O-RAN Alliance and Linux Foundation to support the software development for an open RAN solution that is available to everyone. The community will align with the architecture and specifications that are created in the O-RAN Alliance working groups to create a working software solution to enable an open and intelligent 5G RAN.

 Near-Real-time RIC X-APPs (RICAPP)
 ----------------------------------
 
-RICAPP D Release Feature Scope:
+RICAPP E Release Feature Scope:
 
-New xApps:
-1) Bouncer xApp (HCL, C++): RIC performance measurement xApp - in conjunction with the appropriate E2 Sim, can test E2 control loop latency (INSERT-CONTROL) as well as the scalability of the RIC with regard to the number of E2 Nodes supported.
-2) LP (Load Prediction, ChinaMobile, python): Initial version of a cell load predictor.
-3) HW-P (Hello World - Python, Samsung): A python based demo xApp that demonstrates how an xApp can use the RIC platform features in python.
-4) HW-G (Hello World - go, Samsung): A go-based demo xApp that demonstrates how an xApp can use the RIC platform features in go.
+1) New xApps: RC (RAN Control) by Mavenir - implements subset of E2 SM RC
+2) Improved xApps:
+    a) LP (Load Prediction) by ChinaMobile: Include trained ML model, will populate predictions in inFlux DB
+    b) AD (Anomaly Detection) by HCL: Will identify a new anomaly type (area anomaly), use geo-location as a feature.
+    c) QP (QoE Predictor) by HCL: Include prediction for current serving cell, incorporate predicted load as a feature, provide sequence of predictions.
+    d) TS (Traffic Steering) by UTFPR (University, Parana, Brazil): Call RC xApp to trigger UE handover, improvements in traffic steering logic.
+    e) Bouncer by HCL: Increase performance and functional testing capabilities; continue identifying RIC platform bottlenecks.
+    f) HW (HelloWorld) demo xApps in C++, go and python by AT&T and Samsung: Add usage of more platform features, update usage of platform features that are evolving.
+3) Integration of AD, QP, TS, LP, RC, and KPIMON with Viavi simulator.
+4) Extensive performance benchmarking of the RIC platform using Bouncer and E2 Simulator (HCL)
+5) Design for xApps to support network slicing use case.
 
-Improved xApps:
-1) AD (Anomaly Detection, HCL, python): A ML-based real-time anomaly detection using KPI data populated in inFlux DB.
-2) KPIMON (Samsung, go): Improved version implements E2 SM KPM 2.0.3 version and stored collected data in time series DB (inFlux)
-3) QP (QuE Predictor, HCL, python): A ML-based predictor of UE's throughput if it was handed over to a neighboring cell. The D release version finally uses a ML-trained prediction model and includes the functionality previously provided as a separate QP-driver xApp.
-4) TS (Traffic Steering, UTFPR, C++): Extended version of the TS xApp that now receives anomaly detection messages, requests QoE prediction, and issue control operation to request a UE handover. 
-
-Together, AD, QP, and TS xApps and Viavi E2 Tester, implement a use case where anomaly detection is combined with QoE prediction and traffic steering action to move the affected UEs to a different cell. 
 
 
 Near-Real-time RAN Intelligent Controller Platform (E2 Interface) (RICPLT)
 --------------------------------------------------------------------------
 
-RICPLT D Release Feature Scope:
+RICPLT E Release Feature Scope:
 
-1) Some of the features are demoed here: 2021-06-08 Dawn
-2) REST interface for xApps towards E2 subscription manager. No need to encode E2AP subscription messages in the xApps anymore. The Xapp framework for Go already supports/uses this.
-3) Support for A1-EI (Enhancement information) to xApps
-4) A lot of extra load/scalability testing (using a new bouncer xApp) and functionality testing (E2, ...) was done under RIC-150 using a "bouncer xApp".
-5) Wider scope of the xapp framework for python (RIC-778, RIC-773).
-6) We added InfluxDB as optional platform service time series database (RIC-734)
-7) Support for O2 as per WG6 use case "Deploy xAPP in Near-RT RIC" in O-RAN Orchestration Use Cases v2.0. This also includes a change in how xApps register as part of their startup.
-8) libe2ap (asn1c-based) can be re-used by components to encode/decode E2AP ASN.1 PDUs (Protocol Data Unit)
-9) E2 statistics are now visible as VES metrics events
-10) RMR raises alarms using the RIC alarm system in temporary overload situations
-11) The Near-RT RIC can be deployed on Kubernetes 1.18 and helm 3. For the first time, this and all robot framework based "end-to-end" tests have also been verified in the O-RAN SC lab.
-12) The Near-RT RIC project now achieved the CII (Core Infrastructure Initiative) badge "passing": (link).
+1) We updated from E2APv1.0 to E2APv1.1. The platform now stores OIDs (introduced in E2APv1.1) for the E2SM of E2 function definitions in RNIB. Since E2APv1.1 is backwards compatible with 1.0, you can still connect E2 nodes that support E2APv1.0. Note that for the next release we plan to switch to E2APv2.0 only.
+2) The E2 subscription manager now automatically deletes its stored subscriptions if it gets notified (by the E2 manager) of E2 nodes having disconnected. xApps are expected to do the same and need to re-issue their subscriptions once the E2 node is reconnected. This behavior is different to earlier behavior where the subscription manager kept the subscriptions in such situations. Note that the standard requires the E2 node to delete its subscriptions if there's the E2 interface is disconnected.
+3) The E2 subscription manager now handles various error scenarios that previously were not handled.
+4) We will continue the re-implementation of the A1 mediator in golang in release F. The first parts are already implemented, but in the E release we stay with the "old" python-implementation of the A1 mediator.
+5) On SDL side we now have a SDL CLI that can be used in testing (instead of direct usage of the Redis CLI). The SDL API for findkeys/getkeys now supports glob-style patterns.
+6) The golang SDL API/library now handles namespaces as part of its function signatures instead of this being a global parameter. This eases usage of multiple namespaces from the same application.

 Service Management and Orchestration  (SMO)
 -------------------------------------------
 
-SMO D Release Feature Scope: 
+SMO E Release Feature Scope: 
 
-1) Support for O1 interface
-      Implementation of NETCONF client in SMO
-      Reference implementation of a NETCONF server that O-RAN Network Functions, e.g. Near-RT RIC, CU, DU and RU can use. The code can be found at https://github.com/CESNET/netopeer2
-      A minimal set of YANG models that demonstrate the capability of the O1 interface while satisfying the closed-loop automation use-case.
-2) Support for O1/VES interface
-      Demonstrate the capability to receive VES events, collect them in a dB, and display them in a dashboard.
+1) SMO was extended to support network slicing. In particular, RSAC has come up with closed loop automation use case for network slicing which involves the SMO collecting PM counters related to network slicing, and based on them breaching some thresholds will cause a change in the configuration of the network slice. That means the SMO had to have support for PM counters related to network slicing, and an ability to reconfigure the O-DU for the network slice.
+2) Separately, SMO now implements a disaggregated VES solution that separates the collection of VES events from how it is presented to any application that wants to view them. In particular, all events now get posted on the Kafka bus, and different "connectors" are provided to make the data available in different formats. For example, the "DMaaP Connector" provides an ability for a application to read the message in DMaaP format. Alternatively, if the data needs to be synced to a dB, the "InfluxdB Connector" sinks the data to an InfluxdB.
