Since last time, we worked on Elasticsearch bulk updating, tons of documentation improvements, syslog message processing, flow classification, Cortex in Nephron, time-series tag handling, the new config management API, gRPC support in the twin API, tests, internal stats, Liquibase, Vue UI and geomap, scheduled outages, and Helm.

Release Roadmap
September Releases
OpenNMS is on a monthly release schedule, with releases happening on the second Wednesday of the month.
The next OpenNMS release day is September 8th, 2021.
We currently expect a Horizon 28.0.3 release.
Next Horizon: 29 (Q4 2021)
The next major Horizon release will be Horizon 29.
The current roadmap for Horizon 29 includes the following goals:
- running as non-root by default
- refactor the Minion's communication to get rid of out-of-band ReST calls to the OpenNMS core
- add support for persistence of flows to Cortex
- start the groundwork for replacing the topology UI with a pure-javascript version
Next Meridian: 2022 (Q? 2022)
With Meridian 2021 recently out, we do not yet have a specific timeline for Meridian 2022.
Expect it to include -- at the very least -- the JDK11 requirement and flow aggregation improvements from Horizon 28.
Ideally it will contain work going into Horizons 29 (and probably 30) if our timeline holds.
