Since last time, we worked more on the config management API and importer, thresholding and monitor docs, updating Karaf to 4.3, SNMP metadata provisioning, Minion health check, JMS in the twin API, ReST cleanups and docs, Vue geomap and UI PoC, and flow processing.

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. 😅
