Release Roadmap
July Releases
OpenNMS is on a monthly release schedule, with releases happening on the first Tuesday of the month.
The next OpenNMS release day is July 6th, 2021.
We currently expect at least a Horizon 28.0.1 release, plus updates for all supported Meridian releases.
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.
