For anyone not limited by bandwidth or other internet related restrictions I would suggest that the online manual is the preferred choice. That way you don’t need to wait for a release. Of course, I understand that this is not feasible for everyone.
Although I have had some help, especially from Anders Jonsson, and occasionally some others, the manual is still lacking in volunteers. We could really use more helping hands 
So, if you see something that is outdated or missing information. Don’t hesitate to at least open an issue about it. Even better would be, if you could help write the documentation.
