This past weekend, version 1.5 of goobook was released. The changes were very minor, mostly supporting a newer version of hcsutils and dropping support for python 2.6.
I have uploaded new Wheezy packages to my website. You'll need to update python-hcsutils to the 1.3 version for goobook 1.5. The goobook 1.4 packages are still there though and should still work just fine.
