The main concept remains the same in 2.0. Qlik Sense Desktop client should be considered as an evaluation product, and as such is free of charge (no license fee). Being a client naturally limits the things you can do, when you for example are not running a proper server service. Qlik Sense is a server side product which requires a license, and also provides a full set of features and functions.
Qlik Sense 2.0 is released you will be able to study the features and functions in detail though the documentation, but until then there will not be any public documentation on 2.0 features.
