So I upgraded the Mrs yesterday and myself today. Admin interface is much nicer. If this posts, then XML-RPC works.
My theme works, but I’m going to be changing it so it will work with widgets.
One weird and a little annoying is you have to sign up for a WordPress.com account – which creates a blog for you – just to use the new built in comment spam filtering. But for you the reader I did it and the image thing is gone from comments.
Updates to come.
