I am unsure myself, but there was quite a lot of activity on the Coq side 
on the PG devel mailing list.

I've used 4.2 recently with Isabelle, and found it a bit awkward in some 
details.  Somehow the windows don't pop-up and disappear the way they did 
before, making it hard to work in the two-window mode of the ancient past 
that I am still using.  (If I were still involved, I would have spent a 
few days investigating this, produce tracker items, polish the elisp code 

Maybe I should make an effort to get the hard-wrap for text paragraphs 
work smoothly in Isabelle/jEdit, so that I don't have to go back to Emacs 
just for that (the last thing where I still use the dinosaur).

What I need for the release (on-time before the start of the RC phase) is 

   * A version of Proof General as Isabelle component, like
     (it must be platform/emacs independent, without .elc files).

   * A specification which Emacs.app needs to be included in the
     Isabelle.app -- I will do the final montage myself.

It is then up to remaining PG/Emacs users to test that in the RC phase of 
the release (2-3 weeks before lift-off).  I am not going myself again 
through the agony and desparation to make all this work in all reasonable 
combinations that users might have (as I used to do until October 2011).

So what are the remaining problems?  It is time to list them and sort them 
out if possible.

At the Orleans Isabelle Tutorial someone had a very new Mac and was unable 
to copy-paste from the Output window, but that was Isabelle2012 with the 
Lobo browser, not the Rich_Text_Area of Isabelle/jEdit now.  (I will ask 
him to test again before the coming release).

Anything else that hinders Isabelle/jEdit use, especially on the Mac?
