In October we released a Horizon 26 bug fix release, as well as Meridian maintenance releases on the 2018 and 2019 branches. The biggest news, however, is the release of Meridian 2020.

Meridian 2020

Meridian 2020 is the latest in the Meridian series, based on Horizon 26.1.3 plus a number of bug fixes that have gone into the 26 series since its release.

This marks the end of official support for Meridian 2017, although we will continue to make critical updates to the 2017 branch for Powered By OpenNMS customers.

For a high-level overview of what's changed since Meridian 2019, see the Meridian 2020 landing page. The complete release notes are available on
