February Releases: Horizon 27, and Meridians 2018 through 2020

For February we released point updates to all OpenNMS versions under active support.

Horizon 27.0.4

Release 27.0.4 contains a number of bug fixes relating to WMI, the Minion, flows, reports, JEXL processing, and more, as well as a few small enhancements.

The codename for 27.0.4 is Towel.

For a high-level overview of what has changed in Horizon 27, see What’s New in OpenNMS Horizon 27.

For a complete list of changes in 27.0.4, see the detailed release notes.

Meridians 2018.1.25, 2019.1.16, and 2020.1.5

Meridian 2020.1.5 had a few bug fixes including a timezone fix for Grafana reports and an SFlow fix. Meridians 2019 and 2018 had smaller releases with just a couple of bug fixes.

For a list of changes, see the release notes:

Release Roadmap

March Releases

The next OpenNMS release day is March 2nd, 2021.

Currently we expect a new Horizon release.

Next Horizon: 28 (Q1 2021)

The next major Horizon release will be Horizon 28.
It is currently expected to be released during the March release cycle.

It will primarily contain enhancements to flow processing to handle ToS/QoS (DSCP) aggregation, as well as a refactor of our BGP Monitoring Protocol support to bring it in-core, rather than relying on an external OpenBMP instance.

Next Meridian: 2021 (Q2 2021)

With the recent release of Meridian 2020, plans are still tentative.
However, the current plan is that Meridian 2021 will be based on Horizon 28.

We'll know more once development plans start to firm up.


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

Mynd you, møøse bites Kan be pretti nasti...

We apologise again for the fault in the disclaimers. Those responsible for sacking the people who have just been sacked have been sacked.

Until Next Time…

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.
