🗺️ FatPy Road Map Summary: Planned Implementations

This document outlines the planned implementation schedule for FatPy, providing a high-level overview of the features targeted for each package version. The goal is to inform the community about our development trajectory and solicit feedback on priorities and potential feature sets.

More detailed information for components can be found in Component List available to FABER Members

This is a preliminary plan. Many of additional requirements will emerge shaping the future roadmap.
