OpenNMS September Releases

In September we had Meridian 2017 and 2018 releases, as well as a new major Horizon release: Horizon 25.

OpenNMS Horizon 25

Horizon 25 contains a huge number of bug fixes and enhancements, most notably massive thresholding improvements, big changes to netflow and other streaming telemetry data, reporting and UI updates, plus much more.
