Hi Rees.
As mentioned elsewhere, some personal issues (both health and emotional, unfortunately) have basically put me out of action for several months and as a result v2 development is severely delayed.
I'm back into things since the last month or so and am gradually catching up with a huge support backlog and I'm currently working towards providing an update to the current version of Yummy.
Since v2 is practically a re-write there have already been many unforeseen obstacles which have delayed development, and it's still a long way off being usable even as an early pre-alpha, so I really can't give you a good estimate as to when it will be even in beta form, never mind a release date.
To that end, I'm considering pulling the WebDAV support I've already implemented in what exists of v2 and engineering it into v1 as a free upgrade, which would follow as a v1.9 some time after I complete the update (v1.8.3) I'm working on right now.
I'm sorry I don't have better news for you, but please be assured that I am committed to providing what I promised.
All the best,
Jason
