Release Roadmap

April Releases

The next OpenNMS release day is April 6th, 2021.

Currently we expect new bug fix releases for Horizon 27 and Meridians 2019 and 2020.

Next Horizon: 28 (Q? 2021)

The next major Horizon release will be Horizon 28.

Horizon 28 will still be coming down the pipeline soon.
Currently, we hope for it to contain the move to building with JDK 11 (and, consequently, a requirement to only run on JDK 11 or higher), QoS flow aggergation, and some other improvements in the pipeline.

Next Meridian: 2021 (Q2 2021)

Meridian 2021 is on track for a release in 2nd quarter of 2021. It is expected to be based on the Horizon 27.1 codebase, which means it will contain all of the bug fixes and new features introduced in Horizon 26 and 27.

Until Next Time…

If there’s anything you’d like me to talk about in a future OOH, or you just have a comment or criticism you’d like to share, don’t hesitate to say hi.
