In October, we released updates to all OpenNMS Meridian versions under active support, as well as an update for Horizon 28.
We are currently planning on releasing Horizon 29 next month.
Along with a bunch of bug fixes and enhancements, we have a couple of things that are changing significantly that it's worth noting.
OpenNMS will run as non-root by default.
However, because it is possible to have a significant number of resources writing files into the
$OPENNMS_HOME/sharedirectory, we will not automatically fix ownership of those files on upgrade, because it could take an indeterminate amount of time to run
chownon the entire shared data tree.
Be prepared for some downtime while upgrading.
Amazon SQS support for communicating with Minion will be removed.
RPC communication and the handling of configuration are changing significantly enough that we would need to rewrite the SQS component and we don't believe it to be in wide deployment, compared to using gRPC or Kafka.
Release 28.1.1 contains a number of bug fixes and enhancements, including web UI, Minion, Docker, and documentation improvements.
For a high-level overview of what has changed in Horizon 28, see What’s New in OpenNMS Horizon 28.
The codename for Horizon 28.1.1 is Mikaela Banes.
Meridians 2019 and 2020 included some fixes in how Docker containers are generated, plus an enhancement to queries used by Helm to support more fields in queries.
Meridian 2021.1.5 also contains a number of other bug fixes and enhancements, including web UI and documentation improvements.
