Release Roadmap

Upcoming December Releases

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

The next OpenNMS release day is December 8th, 2021.

We currently expect minor 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.
