Peter's draft is fine.

1) JC1 is based on
http://lists.w3.org/Archives/Public/public-owl-comments/2009Jan/0053.html
which refers to the 02 December 2008  version of NF&R, not current
version

2) I'd suggest not to spot particular sections in NF&R; "less is more"
here also because:
- JC4 "improved versioning support in OWL2" is not precise
- several sections might be relevant, in particular both sections 2
and section 4
http://www.w3.org/2007/OWL/wiki/New_Features_and_Rationale#Features_.26_Rationale
http://www.w3.org/2007/OWL/wiki/New_Features_and_Rationale#Other_Design_Choices_and_Rationale

In addition to answer JC4 request "to give an overview of the
improvements", we may want to provide [1] as a pointer for all.
Specific improvements for NF&R are found in  the corresponding section
in [1] :

"This Working Draft has undergone several changes since the version of
02 December 2008

The new features are described in a more friendly syntax which
improves their readability.
Examples are now also given as RDF graphs
The new section "Other Design Choices and Rationale" approaches OWL 2
syntax and backward compatibility
Significant editing makes it more compact and clear. "
