San Jose- What's new in Lightroom 4.1?

Details
Hello Everyone! As promised, we are hosting the Lightroom User Group Meeting in San Jose this time. We're planning on discussing the new Defringe and HDR Tone Controls introduced in Lightroom 4.1.
One of the suggestions we got at our last meeting was that we provide some time for networking, in addition to the presentation itself. I think this is a fabulous idea, so how about this: bring a photo that you've taken that you love. You can bring it on your laptop, tablet, phone, or printed on an honest-to-goodness piece of paper. Then, while enjoying complimentary pizza prior to the presentation, share your photo with at least one other person (someone not previously known to you!) and talk about why you like it. People who choose not to bring a photo will be publicly scorned.
And please... if anyone has any less cheesy, grade-school-esque ideas for networking activities, please let me know, 'cause this was the best I could come up with off the top of my head! Also, I was kidding about the public scorning.
I'll update this info when I have more details on what we'll be presenting, and I hope to see everyone there!

P.S. The meeting will be held in the "Park" conference room. If you RSVP more than 24 hours before the start of the meeting, and if your Meetup profile contains your full name, then a visitor's badge will be waiting for you when you arrive. If you RSVP late, or your name on Meetup is something like MonkeysRule! then you'll need to get a badge from security when you arrive.
