For CLI there are some stuff missing in the documentation on how to start development server, build-dev and build-prod would be nice to find them there
Another big Questionmark is the update. How can I initate an update and how about v6 are there breaking changes?
I understand, for makeing a new app would it be better to directly work with the beta or do you think it might take time till a stable release is there?
It is already stable but there are still breaking changes can appear. So it is relatively safe to start with. And next week there will be beta of CLI that will scaffold v6 project
