Is there a changelog available for node-machine?

I am looking for a list of changes to be aware of when migrating between versions of `machine`. I have checked:

* https://github.com/node-machine/machine
* http://node-machine.org/

So far, no luck. Have I missed something? Is this document available elsewhere?

Check the node-machine repository and node-machine.org links listed in the issue for an existing migration history. Done means either identifying and linking the changelog source or documenting where version-to-version changes can be found; no project file or test is named.

Written by the indexing model from the issue text.
