All packages are based now on the RDFJS spec. The spec is not yet final, but mainly editorial issues are open. I want to say thanks to all the people who helped creating that spec and made RDF-Ext v1 possible! At Zazuko we used the develop branches already for some projects and were quite happy about the new API and the performance of the stream processing. The lack of documentation is a known problem and we are trying to solve it soon.
