The biggest change is the introduced docker based workflow. That allows to encapsulate the complex setup into a convenient container.
This version is tracking whipper version 0.7.3 as of now. Any new version will be equally included, which might lead to problems.
Upgrade
There are some changes that'll probably break your setup if you are migrating from a previous version. I hope the current state is described properly in the Readme.
