Hey,
Wikibase lib/repo/client is now using version 0.6 of Wikibase DataModel. I wrote a blog on this release a while back: http://www.bn2vs.com/blog/2013/12/23/wikibase-datamodel-released/
This means we can now use the consistent namespaces of DataModel in Wikibase. So over time we should replace usage of the old FQNs with the new ones. When writing new code using DataModel classes, please make sure you are not referring to a legacy alias. If it is not in Wikibase\DataModel, it is a legacy alias.
Cheers
