The SD-RAN community is pleased to announce the release of SD-RAN v1.4. This is the first Apache licensed open-source release, which has been made possible after incubating the project for over a year under the ONF Member only license. All code repositories, helm-charts and documentation are now Apache licensed and available to the community regardless of ONF membership.

The highlights of this release for the RIC platform include the implementation of the O-RAN A1 interface and significant improvements to the onos-config microservice in preparation for a comprehensive O1 interface implementation in upcoming releases.

3rd party integration with xApps from RIMEDO Labs and Intel Labs are supported, and 5G-SA gNBs from Sercomm. A summary of the use-cases, xApps, SMs and their support in this release on various platforms is shown below.
