Since last time, we worked on more documentation, running as non-root, time-series API enhancements, a Telemetryd Karaf CLI, VMware script fixes, Docker Content Trust, and various Vue3 UI exploration.

Release Roadmap

July Releases

In July, we released updates to all OpenNMS Meridian versions under active support, as well as an update to Horizon 28.

Horizon 28.0.1

Release 28.0.1 contains a bunch of bug fixes and enhancements, plus a few security updates.

The codename for Horizon 28.0.1 is Optimus Prime.

For a high-level overview of what has changed in Horizon 28, see What’s New in OpenNMS Horizon 28.

Meridian Point Releases

All Meridian releases this month contained security updates, so it is recommended that you upgrade.

Starting in Meridian 2019, improvements to the Kafka provider were added, and Meridian 2021 includes a bunch of other small bug fixes and enhancements.

For a list of changes, see the release notes:

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 Meridian 2021.

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. 😅
