When new versions of software are released, the KB articles for the previous version are still needed.  KB articles for the new version are also needed.

It would be helpful if the KB had a top-level directory / container / whatever you want to call it - this would allow us to retain the existing Category & Article structure for the current version, and create a new Category & Article structure for the next version.

This also requires an update to the search function so you can limit a search to a container, or search all articles in the KB.
