Just got the update on all the wikis I manage and... Yeah...as to be expected, the extended nav javascript that I and many other wiki admins use has been disabled. I realize that there was no point in hoping it would be the exception, but couldn't you at least provide native support for it beyond the third level? (Whoops, initially wrote 'first').
