In the last week we merged some old pending enhancements and cleanups, worked more on wrapping up the OpenConfig and Minion-based remote poller features, and fixed a bunch of bugs.

Release Roadmap

Note that this is just based on current plans; dates, features, and releases can change or slip depending on how development goes.

September Releases

The next OpenNMS release day is September 1st, 2020.

Currently we expect new bugfix releases from Meridians 2017 through 2019.
Also we'll be releasing Horizon 26.2, which will add OpenConfig support on top of the existing Horizon 26 stable codebase.

Next Horizon: 27 (Q4 2020)

The next major Horizon release will be Horizon 27, due in 4th quarter 2020.
It's going to contain a bunch of great stuff:

  • improvements to node caching for flow processing
  • VMware meta-data has been moved from assets to the new node meta-data
  • Minion improvements, including configuration enhancements and an overhaul to RPC thread-handling
  • a new handy global search bar in the web UI
  • improved SNMPv3 auth configuration
  • a major rework of remote poller functionality, now integrated with the Minion (we're calling it Application Perspective Monitoring)

Next Meridian: 2020 (Q4 2020)

Meridian 2020, based on Horizon 26.1, has been pushed back a month for some more polish.

We now hope to release it for the October release window.

Until Next Week…

If there’s anything you’d like me to talk about in a future OOH, or you just have a comment or criticism you’d like to share, don’t hesitate to say hi.
