Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

In this sense, we interpret the "Public API" of a hardware module as its port/parameter list. Versions of the IP in the same major relase are "pin-compatible" with each other. Minor relases are permitted to add new parameters as long as their default bindings ensure backwards compatibility.
