Canonical source of documentation for jointSpace?

[signaleleven]

Hello,

Not exactly an issue with the library, but a general call for help.
Is there an official source of documentation for jointSpace v6?
I have one of the models with v6, but without Android. Everything covered by the library seems to work, so I don't hold much hope to get more out of it, but I'd love to be able to switch sources like in previous versions.
Did Philips ever publish anything official?

http://jointspace.sourceforge.net/projectdata/documentation/jasonApi/1/doc/API.html
This is (official?) is only for v1 (and usable for ambilight on v6, out of scope for this library maybe - would work https://github.com/jomwells/ambilights) but I am tired of guessing my way through it. Does anybody know of another more modern authoritative source of documentation for jointSpace?
