This Week in OpenNMS - November 19th, 2018 - Correlation, Topology UI, Core Upgrades, Meridian and Horizon

It's time for This WeekThese Weeks in OpenNMS!

Apologies for missing last week but I got a bug of my own and by the time I was feeling up to writing TWiO I figured I might as well just punt to the next week. I assure you, I lived. OR DID I?

In the last few weeks we did more improvements to OCE, a number of topology improvements and fixes, and worked on updating a number of core tools including Kafka and Vaadin to newer versions. We also released Meridian 2017.1.13, 2018.1.3, and Horizon 23.0.1.
