This is just a release to keep the current beta active.
No work has been done since beta 1.3 with the exception of the use of trusted root code signing.
I am back working at the app now and am working towards a first public release in the early new year. No new features to be added. Just the hard graft of stabilising what is present. Anyhow, it will make a change from wrestling with the talented but unruly monster that is CoreData.
This is release candidate 2, a necessity forced upon us by the discovery of a bug that prevented the document from being marked as dirty when new images were added or user units were deleted. The issue had been introduced when providing Snow Leopard compatibility.
