Is this normal that http://code.appinventor.mit.edu server is not updated as the ai2.appinventor.mit.edu ?

No, but as you can see it is currently the case.

That's expected. We haven't pushed the new release to code.appinventor.mit.edu yet. So long as you aren't using features from the newer release your app should continue to work.
