I have a project starting up that I'm planning to build using Umbraco V8. I recently signed up for Umbraco.tv. I wanted to use the training videos to get myself up to speed quickly. I noticed that there is limited content for V8 (Only covers document types under the implementer section and doesn't have anything for developer).

I get that V8 is fairly new so it might take some time for that section to get more content. Is going through the implementer and developer sections for V7 worth my time, or are the versions too different?
