Release Roadmap

May Releases

The next OpenNMS release day is May 11th, 2021.

Currently we expect a new Horizon 27 release, as well as Meridians 2019, 2020, and 2021.

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

Until Next Time…
