v0.4.0 Bring with it some major changes. If you're upgrading from a previous release, please run ./scripts/init.sh and remove any bower components from vendor. Bower now uses the bower_components directory. NOTE: Depending upon your connection and processor speed the build can take a substantial amount of time (3 - 15 minutes). The bower step is particularly slow, because it downloads the complete git history. If you think that there might be a problems, check you network traffic. If the build is still downloading then it's still working.
