Hi,
Thanks for checking the event registry. Did you have a look at:
https://blog.flowable.org/2020/02/08/introducing-the-flowable-event-registry/
Maybe you can explain what you are missing in this article, so we can focus on providing content to address this?
We still have to determine a realistic release date for the next release, when this is known we will update the roadmap page.
Best regards,
Tijs
