I don't see anything on the horizon here; I think we have to declare
breqn, mathstyle and flexisym fundamentally incompatible with
unicode-math. They change so much that a tremendous amount of work
would be required to make them compatible. Somebody has to do this
directly within those packages.

Where do these version numbers come from?
