I've used the new beta since it came out. Yesterday I wanted to copy some keywords from an image in 2010 and saw, very stressfully, there were no keywords or any data other than time of shot in that image. In fact, no data was showing for 2009, 2010, and early 2011 NEF files. I then realized the data was there because I could see it in ViewNX2. So I reverted to 4.6.8 and everything's fine. The files missing data were older NEF files edited in NX2 (no side cars). But there were some more recent NEFs that were ok. Also, there were some jpegs from canon camera back then that were ok. I've never had an issue with a beta before but I'm doing ok with 4.6.8 again.
