April Releases
In April, we released updates to all OpenNMS versions under active support.
Horizon 27.1.1
Release 27.1.1 contains a few enhancements, as well as a number of bug fixes including some XSS and CSRF cleanups and a Jetty DoS CVE.
The codename for 27.1.1 is Infinite Improbability Drive.
For a high-level overview of what has changed in Horizon 27, see What’s New in OpenNMS Horizon 27.
For a complete list of changes in 27.1.1, see the detailed release notes.
Meridian Releases
Meridian 2018.1.27 was a small release, with just the Jetty CVE update and a new option for tuning Minion communication with OpenNMS.
Meridian 2019.1.18 added on top of that a number of other useful bug fixes including some cosmetic UI cleanups and a fix to Kafka producer resource naming.
Meridian 2020.1.7 contains all of those changes, plus a few other bug fixes and a performance improvement in the Kafka producer.
For a list of changes, see the release notes:
Release Roadmap
May Releases
The next OpenNMS release day is May 11th, 2021.
Currently we expect a new Horizon 27 release, as well as Meridians 2019 and 2020.
Next Horizon: 28 (Q? 2021)
The next major Horizon release will be Horizon 28.
Horizon 28 will still be coming down the pipeline soon.
Currently, we hope for it to contain the move to building with JDK 11 (and, consequently, a requirement to only run on JDK 11 or higher), QoS flow aggergation, and some other improvements in the pipeline.
Next Meridian: 2021 (Q2 2021)
Meridian 2021 is on track for a release in 2nd quarter of 2021. It is expected to be based on the Horizon 27.1 codebase, which means it will contain all of the bug fixes and new features introduced in Horizon 26 and 27.
