In the last week we did more work on flow aggregation (including ToS and QoS), continued to work on the OpenBMP migration, JDK 11 builds, JEXL cleanups, time zone handling, Minion metrics in Prometheus, and more.

## Release Roadmap

### February Releases

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

The next OpenNMS release day is February 2nd, 2021.

Currently we expect a point release for Horizon and all active Meridians.

### Next Horizon: 28 (March 2021)

The next major Horizon release will be Horizon 28.  
It is currently expected to be released during the March release cycle.

It will primarily contain enhancements to flow processing to handle ToS/QoS (DSCP) aggregation, as well as a refactor of our BGP Monitoring Protocol support to bring it in-core, rather than relying on an external OpenBMP instance.

### Next Meridian: 2021 (Q2 2021)

With the recent release of Meridian 2020, plans are still tentative.  
However, the current plan is that Meridian 2021 will be based on Horizon 28.

We'll know more once development plans start to firm up.
