In the last few weeks we did very little, as The OpenNMS Group is officially on holiday from Christmas to the New Year. However, a few small changes made it in before everyone disappeared for a while.

No matter what you celebrate, I hope y'all had a good holiday while we were radio silent, and have a better 2021 than you did 2020.

Release Roadmap

January Releases

The next OpenNMS release day is January 5th, 2020.

The current expectation is that there will be Meridian 2019 and 2020 bug fix releases, as well as a Horizon 27.0.3 release with bug fixes.

Next Horizon: 28 (Q1 2021)

The next major Horizon release will be Horizon 28.

We're still deep in the development cycle for it, but at a high level it is expected to contained our finished work moving OpenBMP's functionality into OpenNMS, as well as enhancements to handle ToS/QoS in flows.

Next Meridian: 2021 (Q2 2021)

With the recent release of Meridian 2020, plans are still tentative.
However, the current plan is that Meridian 2021 will be based on Horizon 28.

We'll know more once development plans start to firm up.
