OpenNMS May Releases

Last week we released OpenNMS Horizon 24.1.0, and new point releases for Meridian 2016, 2017, and 2018.

The Meridian releases contained primarily small UI fixes and a couple of security fixes. Horizon 24 got a decent number of bug fixes and enhancements including support for OpenTracing in the sink API and a rework of geocoding services.
