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

<!--
git log --no-merges meridian-2016.1.23-1..origin/release-2016.x -- . ":(exclude).circleci"
-->

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. ![😅](https://s.w.org/images/core/emoji/13.1.0/72x72/1f605.png)
