Thanks, Nick. I'll try to get it done this weekend.

I've uploaded Misc/NEWS and Doc/whatsnew/3.3.rst (my apologies to Antoine 
for plagiarizing the first sentence, I found it hard to come up with a 
better version).

I wasn't sure whether to put the "whatsnew" entry into the section
"Other Language Changes" or into the PEP section. I chose the latter,
since many new features have been added that are part of the PEP.
