In our recent (July) team retrospective, we didn't have a chance to review the action items that came out of our June retrospective. However, I have posted those previous items, with status updates (as best I know them)[1]. Of the 18 items, 5 are "done", and several others are improved or in progress.

That page will also contain our July retrospective notes, after they have been processed.
