The Zenhub has up-to-date Epics that Besu development is targeting over various releases. See the roadmap tab on the Public Zenhub here: https://app.zenhub.com/workspaces/hyperledger-besu-61fc06f457da1c0017f6347d/roadmap
This document represents the current working roadmap for Besu. It is a living document, which will evolve and change over time. In particular the features in later versions are likely to change.
We use the approach of #now, #next, #later used by foursquare, with a slightly different time horizon. Our #now scale is about 3 months, #next about 6 months, and #later is 12+ months.
