since this is V2, i couldn't find a changelog? The first one was one
year ago, so it's very hard to remember. In such a case a link to the
last version is also helpful.
Recently i saw you have a Github account. For such a complex series it's
also very helpful to provide a link to a working test branch with this
series applied. It's not a must, but appreciated.
Best regards
