Hi,
thanks for your feedback and for pointing out the issue with the missing indication that the ACC V1.9 setting can also be used for higher versions, e.g. ACC V2.
We have already relabeled this for an upcoming version.
Just to clarify again:
ACC V1.4 should read ACC <= V1.4 (legacy ACC)
ACC V1.9 should read ACC >= V1.9 (new ACC)
So basically, there are only two types of ACC out in the wild: old and new one
The new line began with ACC V1.9 and continues with ACC V2.x releases.
Sorry for the confusion and thanks for your interest in ACC and trying it out.
Cheers,
Henning
