Web, ReST, and UI

OpenNMS February Releases

On February 4th we released Meridian 2019.1.3 and Horizon 25.2.0.

Both releases contained a few bug fixes, most notably a fix for some NPEs as well as a performance issue in topology processing.

Additionally, Horizon 25.2.0 included an enhancement to the sink API to persist to disk when the Minion can't reach the broker.
