There's a minor change required in the grammar (currently prefixes are allowed to contain a : character, which shouldn't be permitted), but as soon as that is done then SPARQL 1.1 Query will be published as a Last Call Working Draft. I expect it within a week (or so).
ARQ tends to track the latest editors' draft from the SPARQL Working Group. It is typically one of the first systems to implement and test changes to the proposed spec. So ARQ is going to support whatever was the most recent editors' draft when it was released. That's hard (but not impossible) to track for historical versions, but easy enough to tell when a version of ARQ comes out. With the exception of BINDINGS/VALUES there haven't been significant changes lately, and with the Last Call coming up I don't expect that there will be any more (it would have to be a major problem to reopen the process at this point). So users can work with the Last Call Working Draft with reasonable confidence that this will be the final version. The current editors' draft is the one that will be published (with the one issue I already mentioned).
