New minor versions of Hoppy packages have been released.  Hoppy now includes Setup.hs hooks for easy packaging of bindings, and callbacks are default-constructable on the C++ side.

As well, Qtah 0.3.0 has been released, with lots of new graphics and model-view classes, fixes to build under Homebrew on OS X, and with qtah-cpp using a parallel build by default now.  Also, because even Qt 4.8 is old now, support for versions of Qt before 4.8 is now dropped.
