Yet more NEWS from that changeset:

* Attributes "where" and "of" allow an optional context of local
variables ('for' declaration): these variables become schematic in the
instantiated theorem.

The changeset shows all that on its own 
http://isabelle.in.tum.de/repos/isabelle/rev/04448228381d, but this should 
be obvious on this mailing list anyway, which is ultimately about the 
ongoing flow of the repository.
