Argh! thats a bummer. Much that is great will be lost because whenever this sort of thing happens you generally cant find enough people to refactor great ideas from old code to new. Cheers for the heads-up.
A lot of the changes are pretty straight forward, once you get the hang of it.
On the plus side, if you code it with the current structure into functions, there are some programs out there that will convert it for you. That said, the resulting code will probably need to be looked over for optimization, but...it's something.
Fair point, did wonder if there would be converters of some kind. I have a pile of redstone and command block structures - probably easy enough to work out but....
