The table only includes new arrangements put in place in the period 1 October 2012 to 30 September 2013, and is not a full summary of all transfers of responsibility and arrangements not to receive papers that have been made or are currently in place.
Older arrangements from 2009 - 2010 are available here [PDF], and I currently have an OIA in to fill in the gap.
The information will be released annually. Hopefully that will be enough to allow proper monitoring by the media.
(Meanwhile, for a "proactive" release, this wasn't very proactive. It was released on dump day (under cover of the John Banks and red zone court decisions / Rena inquiries / PISA report), there appears to have been no press release, and I only found it because I knew that it was coming and bothered to look for it. You'd almost think the Cabinet Office didn't really want anyone to notice...)
