The current version whitepaper is too short and simple to understand the technologies behind the project.
So, will the team release a new version whitepaper to introduce more details about technologies and applications of Aeternity project?
I think you can know the detail by the github.The link is https://github.com/aeternity/protocol
We will be releasing an updated whitepaper but it is most likely not going to happen before the mainnet launch. The protocol docs @xuanyu linked are definitely the way to go, if you wan to have most of the details.
