Since last time, we worked on documentation, Karaf, the classification engine, the Minion, Docker, running as non-root, health check, config management, CircleCI, Scriptd, SNMP, JMX, the Twin API, IFTTT, flows, traps, Enlinkd, requisitions, Provisiond, Geomaps, the Vue/FeatherDS UI, and OpenAPI ReST updates.

Release Roadmap

Upcoming October Releases

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

The next OpenNMS release day is October 13th, 2021.

We currently expect a Horizon 28 release, as well as all supported Meridians.

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. 😅
