A more detailed account of everything included is included in the dev to master PR for this release: ucb-bar/chipyard#500
- A new Top-level module, ChipTop, has been created. ChipTop instantiates a "system" module specified by BuildSystem. (#480)
- A new BuildSystem key has been added, which by default builds DigitalTop (#480)
- The IOBinders API has changed. IOBinders are now called inside of ChipTop and return a tuple3 of (IO ports, IO cells, harness functions). The harness functions are now called inside the TestHarness (this is analogous to the previous IOBinder functions). (#480)
- IO cell models have been included in ChipTop. These can be replaced with real IO cells for tapeout, or used as-is for simulation. (#480)
- CI now checks documentation changes (#485)
- Support FireSim multi-clock (#468)
- Allows make variables to be injected into build system (#499)
- Various documentation/comment updates (#511,#517,#518,#537,#533,#542,#570,#569)

- This repository used to be "project-template", a template for Chisel-based projects. Through tighter integration of multiple projects from the Berkeley Architecture Research group at UC Berkeley, this repository is re-released as Chipyard - a framework for agile hardware development of RISC-V based Systems-on-Chip.
