Primarily improvements of features introduced in release 1.4.0, including improvements to the FPGA prototyping flow and to FireSim multiclock support, as well as several new features supporting usability within the Hammer VLSI flow. Updated Gemmini version, and mutli-accelerator support in ESP Spike.

A more detailed account of everything included is included in the dev to master PR for this release: #773
