Lightroom 3.5 and Camera Raw 6.5 released with NEX-5N support.
Thanks Uwe, it supports A77 as well.
The GXR+A12-M is included too, but honestly I can't see any difference between what it does now vs v3.4.1 just yet.
Godfrey, the noise reduction at high ISO for the A12 should be better in 3.5 than in earlier versions.

I'll do some testing... It's easier when you know what you're looking for! :-)
