Changelog

In this repository, changes are made in branches which are merged into develop. Those changes should also update this file under "Unreleased Changes". Periodically a release branch is made which updates the crate version in Cargo.toml and is merged into main. The main branch thus only has commits corresponding to releases of the firmware. Once the release has been merged into main it is tagged, and the changes are then merged back into develop.
