I'm quite a bit of the pace I originally envisioned as I wanted a full Clojure API and a REST API that covered items, taxonomies and search in July so I could be working on the command-line client by August. I have a Clojure API that covers items and collections and a REST API that covers items. It will be another 2 weeks before I'm working on the commandline client.
Implemented collection/valid-collection-update? and collection/update-collection.
Added a changelog.
Start work on listing items in a collection API and tests.
