This release is the the result of the short 3.3 dev cycle which mostly
focussed on consolidating the "elements" and "core" libraries into a
single standard distribution.
There were also a number of refinements and bug fixes, as well as some
work to support a simplified out-of-the box experience.
We've created a 3-4-support branch to accommodate any bug fixes for
later 3.4 releases.
