try to use SMW dev-master if you need MW 1.35 or alternatively MW 1.31 with SMW 3.2.3

[AID-PMBD]

Thank you, installing the dev-master solved the issue for me. I am now using SMW 4.0.0-alpha (e7a67a1)

[AID-PMBD]

Sorry, I installed Semantic Approved Revs last week, but didn't get to testing it. It shows up in my Special Page:Version, but it doesn't create the properties as shown in the demonstration Video.

Is there an additional step I have to go trough?
