Breaking Changes in Horizon 29
With Horizon 29 slated for next month, I wanted to take a moment to note some changes that are coming.
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 runchownon 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 Roadmap
Completed October 2021 Releases - Horizon 28.1.1, Meridians 2021.1.5, 2020.1.13, 2019.1.24
In October, we released updates to all OpenNMS Meridian versions under active support, as well as an update for Horizon 28.
Horizon 28.1.1
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.
Meridian Point Releases
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.
For a list of changes, see the release notes:
Upcoming November Releases
OpenNMS is on a monthly release schedule, with releases happening on the second Wednesday of the month.
The next OpenNMS release day is November 10th, 2021.
We currently expect the first release in the Horizon 29 series, as well as a Meridian 2021 update.
Next Horizon: 29 (Q4 2021)
The next major Horizon release will be Horizon 29.
The current roadmap for Horizon 29 includes the following goals:
- running as non-root by default
- refactor the Minion's communication to get rid of out-of-band ReST calls to the OpenNMS core
- add support for persistence of flows to Cortex
Next Meridian: 2022 (Q? 2022)
With Meridian 2021 recently out, we do not yet have a specific timeline for Meridian 2022.
Expect it to include -- at the very least -- the JDK11 requirement and flow aggregation improvements from Horizon 28.
Ideally it will contain work going into Horizons 29 (and probably 30) if our timeline holds.
