ETSI Open Source MANO announces OSM Release NINETEEN, bringing a significant modernization of its codebase

 

 

Sophia Antipolis, 02 February 2026: ETSI is proud to announce OSM Release NINETEEN, a Standard release of OSM, produced by the OSM Community, meeting the established cadence of two releases per year.

OSM Release NINETEEN brings a modernisation of the codebase and dependencies and makes future development easier and friendlier for OSM contributors in multiple key areas:

  • LTS and code maintenance.
    • Python 3.13 in all Python-based modules. This release updates all Python-based modules to use Python3.13 version, which will prevent EOL of Python versions.
    • Angular Framework upgrade for NGUI. In addition, the Angular Framework has also been upgraded for the GUI module to use the latest Angular framework.
    • Upgrade of Kubernetes version and Helm version in OSM modules. All OSM modules have been properly updated to support the latest versions of Kubernetes and Helm, and their associated libraries, which will guarantee the flawless interaction of OSM with modern Kubernetes clusters in the public clouds, even with the Kubernetes versions planned for the next year.
    • Updates of the OSM installation to use the latest versions of operating system and dependencies. Ubuntu 24.04 LTS has been selected as the new base Operating System for community installation of OSM, and the OSM installer has been updated to work flawlessly with the new OS. In addition, the installer supports upgraded versions of subcharts in OSM helm chart and upgraded client tools, all oriented to grant community support of these dependencies for the coming years.
  • Friendlier OSM development.
    • Self-contained repos. Until this release, OSM contributors had to know the intrinsics of OSM to know how to contribute to an OSM module, which added unnecessary difficulty to the process. This release has made every OSM repo fully independent by discontinuing the Debian package generation, simplifying the dependencies on common modules, and providing a single Dockerfile and Jenkinsfile per module that will allow OSM developers to test their code easily and replace existing modules on a running OSM installation. In addition, all contributions to OSM will be tested by a simplified pipeline, much easier to follow and maintain.
    • New pipelines to automate project management tasks. Finally, this release will incorporate an automated pipeline to ease the launch of point releases, transforming this process into a one-click operation. In addition, besides the daily jobs that run daily E2E tests of OSM in our internal testbeds, new pipelines will run weekly to monitor our stable releases, mimicking the OSM installation done by our end users, and allowing us identifying promptly errors in any OSM outdated dependencies.

 OSM at the Join SDG Ecosystem Day

ETSI OSM as other ETSI SDGs, was actively involved in the Joint SDG Ecosystem Day held online in November 2025. OSM community members delivered presentations and live demos of ongoing research and innovation within the OSM ecosystem. These presentations highlighted key advances in cloud-native technologies, with a strong focus on orchestration of telco cloud infrastructures, and energy efficiency for next-generation networks. This active participation reflects ETSI OSM community’s commitment to collaborative innovation, ecosystem-driven development, and the evolution towards sustainable telco cloud architecture
