I've been playing with the Beta a little bit. Been stable so far so I wouldn't have any worries if you want to try it out. There is one thing I really don't like about 2.0 though. In the develop module your tools (crop, spot removal, etc) in version 1.x it's along the bottom of the screen but, in the beta, they've moved it to the top of the right hand menu, just below the histogram. Not sure why it bugs me so much, maybe just too used to the old layout??? I do really like the retouch tool so far. Not something I would use now with my current work flow but, it is a nice option that works well. One other nice thing is in the detail section, there is a 100% crop thumbnail so you can see the effects of sharpening, etc without having to zoom in the main version like before. Hmm, what else? Oh yeah, there's a new vignette function. If you remember before, vignetting would only apply to the original crop. Now there is a "post crop" vignetter option.
