It’s time for OpenNMS On the Horizon!

In the last couple of weeks we merged a number of new features that have been in the works for a while (graph service, off-heap storage), fixed a bunch of bugs, and started on reworking some documentation.

## Github Project Updates

### **Internals, APIs, and Documentation**

- Markus enhanced the new graph API to expose status information.
- Patrick continued his work refactoring the time-series APIs.
- Chandra continued his work on adding gRPC support for the Minion.
- Matt fixed another bug in the dreaded syslog date parsing algorithm.
- Bonnie made a bunch of improvements to the Helm documentation.
- Marcel fixed a bug where datacollection failures could be masked by auto-clean.
- Chandra fixed some issues with using the default foreign source during discovery.
- Christian worked on normalizing our Karaf shell commands.
- Markus worked on fixing a performance issue with locking in ALEC topology updates.
- Pierre, Jesse, and I worked on fixing build issues with Maven Central blocking non-HTTPS connections.
- Dustin continued his work on BMP support in Telemetryd.
- Pierre converted events internally to be immutable.
- Markus started adding graph API support to OIA.
- Chandra worked on making Kafka RPC topics more configurable.
- Matt finished his new implementation of off-heap storage for the sink API.

### **Web, ReST, and UI**

- Qauseen added pagination to the node search modal in Helm.
- Qauseen fixed a performance issue where the Helm panel would refresh for each alarm being cleared, rather than when it finished.
- Markus and I worked on fixing custom date formatting in AngularJS.
- Christian fixed an NPE in the MIB compiler.

## Calendar of Events

### **February Releases - February 4th, 2020**
