Breaking Changes Coming 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
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 (Q1 2022)
The current expectation is that we will release Meridian 2022 in Q1 of next year. It will be based on Horizon 29 plus any bug fixes that happen between November and the Meridian release.
