This release focuses on improving the user experience, enhancing the documentation, and adding new features to the FABulous framework.

Key Features & Enhancements:

FABulous CLI: An interactive shell has been introduced to streamline the workflow of generating and testing fabrics.
Geometry Generation for FABulator: The geometry generation has been improved to support the FABulator GUI, allowing a
better visualization and debugging of the fabric.
Improved Documentation: The documentation has been significantly updated with more detailed explanations, examples, and
tutorials. This includes a new section on the VPR and nextpnr flows, as well as a guide on how to use the new FABulous
shell.
Enhanced Error Handling: The error handling has been improved to provide more informative messages, making it easier to
debug issues.
Refactored Codebase: The codebase has been refactored to improve modularity and maintainability.
Bug Fixes and Stability Improvements: Numerous bug fixes and stability improvements have been made across the entire
toolchain.

Known Issues:

CRITICAL: Non-power-of-two multiplexers in switch matrices can cause serious errors in fabric, npnr model and bitstream spec generation.
The documentation is still a work in progress.
VHDL simulation setup is broken.
