The Zachman Framework is a grid of artefacts used to describe an enterprise architecture. Zachman does not require the whole grid filled. Nor is it necessary for only one artefact to correspond to each hook. It is therefore a fairly messy key holder. Nevertheless it is pretty handy. It prompts the architects to think about what is needed in a particular grid position.
About this new release, I think it has minor changes. The operations angle has changed a bit.

If you know ZIFA, take into account that ZIFA (http://www.zifa.com/) is going to be dissolved at the end of the current calendar year, as John Zachman has said.
