Hello Daniel! Good to hear from you!
I believe this is a consequence of some refactoring we have been doing
on internal graph contexts for TBC-ME and TBL when using
PerformUpdate. In short, you'll need to specify the graph the query
will operate on using INSERT INTO <graph> {}. Sorry this has broken
some legacy scripts.
Actually the latest draft for SPARQL 1.1 Update is worth looking at -
http://www.w3.org/TR/sparql11-update/#t415, which also requires that
the graph be explicitly stated. The full syntax won't be supported
until the standard is finalized, but it will give you some ideas on
the changing landscape for SPARQL Update.
