November Releases - Meridian 2019, Meridian 2020, Horizon 27

November saw bugfix releases from Meridians 2019 and 2020, but most notably saw the (soft) launch of Horizon 27.

Horizon 27 includes a ton of fixes and improvements, but the largest change is the removal of the Remote Poller in favor of a new Minion-based polling mechanism we're calling Application Perspective Monitoring.

Please note that it also includes some changes to VMware metadata handling that we found issues in after releasing. If you use the VMware integration, please hold off on upgrading until 27.0.1 comes out (as soon as we've confirmed the fixes).

Release Roadmap

November Releases

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

The current expectation is that there will be updates to Horizon 27.0.2 and Meridian 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.
