Searching in some of the last 5.0 posts and this, Ting Thing had adviced that 5.0.0 will have some bugs, and some smaller updates will fix those bugs, so... I think is not really something to alarm, it's not a surprise, he advised us that today, May 1st, the 5.0 will be released, and a big number of bugs will be there, and he can't fix them before May 1st...
Well, hopefully, those bugs will be easy to fix for Ting Thing...
