any updates?

[SokratisVidros]

@paulwer can you please fix the rebase conflicts to continue with the final review?

[paulwer]

@SokratisVidros @rifont i have pulled the next branch into this PR and fixed the conflicts.
tbh @rifont has added multiple stuff, which i cannot validate, so maybe a final review by him again is necessary.

[paulwer]

@SokratisVidros @rifont I've reworked the documentation section to fit to this PR.
If you have any questions/additions/feedback, please let me know.
