This is a reminder / retroactive breaking change announcement for the
Wikidata Query Service and Wikibase RDF model.
The change was already announced
and we invite you to review that announcement if you haven’t seen it
before; but that email was quite a while ago, and we also didn’t send it to
all of the usual channels, so we wanted to send this email to ensure
everyone is aware of the change.
The most important part: queries that tested for blank nodes using the
standard isBlank() SPARQL function must now use wikibase:isSomeValue()
