May Releases

May release day was the 5th, and it brought updates to both Horizon and Meridian.

Meridian 2017.1.23, 2018.1.19, and 2019.1.7

We introduced new Meridian versions for 2017 through 2019, mostly with minor bug fixes and a few documentation enhancements in 2019.

Horizon 26.1.0

Horizon got a more substantial update, with bug fixes, a Prometheus collector, Graphite listener support, an Influx timeseries implementation, and a whole bunch of flow and other enhancements.

Calendar of Events

June Releases - June 2nd, 2020

The next OpenNMS release day is June 2nd, 2020. Currently we expect point/bug fix releases of Meridian 2019 and Horizon 26.

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.
