Since last time, we worked on the new config API, more doc updates, non-root fixes, the new Twin API, Nephron, Vue geomaps, and a discovery ReST API.

Release Roadmap

August Releases

OpenNMS is on a monthly release schedule, with releases happening on the second Wednesday of the month.

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

We currently expect a Horizon 28.0.2 release, plus updates to all supported Meridian releases.

Next Horizon: 29 (Q4 2021)

The next major Horizon release will be Horizon 29.

The current roadmap for Horizon 29 includes the following goals:

  • running as non-root by default
  • refactor the Minion's communication to get rid of out-of-band ReST calls to the OpenNMS core
  • add support for persistence of flows to Cortex
  • start the groundwork for replacing the topology UI with a pure-javascript version

Next Meridian: 2022 (Q? 2022)

With Meridian 2021 recently out, we do not yet have a specific timeline for Meridian 2022.

Expect it to include -- at the very least -- the JDK11 requirement and flow aggregation improvements from Horizon 28.
Ideally it will contain work going into Horizons 29 (and probably 30) if our timeline holds. 😅
