This release incorporates months of work on updating the experimentation workflow for hotstuff. Now we have a brand new tool that can deploy and execute experiments on remote servers and collect results -- all written in Go!

This release also introduces a new module system, an implementation of a simplified hotstuff protocol, and other improvements.

Some of the APIs are now maturing, while many are changed since the last release. I have more experience with the system as a whole now, so I hope the APIs will remain somewhat stable in the future.

This release fixes some spelling mistakes in the documentation.

This release includes bug fixes and documentation updates.

This is the first pre-release of a modular relab/hotstuff.

This is the old version of relab/hotstuff before it was rewritten with modularity in mind.
