The documentation (user manual) is not realy "up to date".
A lot of new features described in the release notes (e.g. new authorization concept with V6.4) are nowhere described in detail.
Current user manual version I can find on these website is V 6.3 Nov. 2016.
Current Softwareverison 6.4.2 July 2019! Is there an other "source" existing, which I don't know?
There has been a delay due to holidays. We are actively working on this, Let me find out from the team drafting the documents.
