Starting with Orbeon Forms 2016.1, Orbeon Forms uses a versioning scheme with the number of the year first followed by the number of the major release during that year.
Since 2020 we have switched to one major release per year. Minor releases, when needed, have an extra digit like 2018.1.1, 2018.1.2, etc. This doesn't impact subscriptions or support.
Orbeon Forms 4.0 and newer
The following table lists all the release since Orbeon Forms 4.0 as well as the current status of support.
