## Release Roadmap

### November Releases

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

The next OpenNMS release day is December 1st, 2020.

The current expectation is that there will be updates to Horizon 27.0.1 and Meridians 2018 through 2020.

### Next Horizon: 28 (Q1 2021)

The next major Horizon release will be Horizon 28.

We're still early in the development cycle for it, but at a high level it is expected to contained our finished work moving OpenBMP's functionality into OpenNMS, as well as enhancements to handle ToS/QoS in flows.

### 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.
