It's time once again for OpenNMS On the Horizon.

Since last time, we worked on config manager migrations and importing, flow docs, protobuf updates, non-root validation, topology provider and wiki migration docs, CI improvements, device config backup, Karaf tools and upgrade, TFTP support, flow thresholding, resource and health REST endpoints, vue charting, Helm and OpenNMS.js.

Release Roadmap

Completed January 2022 Releases - Horizon 29.0.5, Meridians 2021.1.10, 2020.1.18, 2019.1.29

In January, we released updates to all OpenNMS Meridian versions under active support, as well as Horizon 29.

Horizon 29.0.5

Release 29.0.5 contains a number of bug and security fixes, as well as a few enhancements.

It include an update to the latest Log4j2 release. It is not believed that we are vulnerable to the Log4j issues fixed in these newer releases, but are updating anyway just to be sure.

For a high-level overview of what has changed in Horizon 29, see What’s New in OpenNMS Horizon 29.

The codename for Horizon 29.0.5 is Kingfisher.

Meridian Point Releases

Meridians 2019.1.29 and 2020.1.18 contain a Log4j version bump, plus an NPE fix in the topology UI.

Meridian 2021.1.10 adds on top of that some Javascript dependency updates and doc improvements.

For a list of changes, see the release notes:

Helm and OpenNMS.js

After adapting to the new process for getting plugins validated, Helm 7.3.0 is now available in the official Grafana plugin registry, and there should be less lag going forward getting updates released.

Additionally, OpenNMS.js 2.4 is now available, which adds support for optimized node resource querying, and a ton of depedency updates to keep up with upstream node security patches.

Upcoming February Releases

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

The next OpenNMS release day is February 9th, 2022.

We currently expect updates to Horizon 29 and all supported Meridian releases.

Next Horizon: 30 (Q2 2022)

The next major Horizon release will be Horizon 30.

Horizon 30 is currently expected to have the following features:

  • the start of a new Vue-based UI using the Feather Design System
  • thresholding support for Flow data
  • support for running OIA plugins on Minion and Sentinel
  • support for backing up router configuration files

Next Meridian: 2022 (Q1 2022)

The current expectation is that we will release Meridian 2022 in Q1 of next year. It will be based on Horizon 29 plus any bug fixes that happen between November and the Meridian release.
