There is now no need to wait until the dot release. In other words i am assured that the dot release will 'replace' the tone curve on my old images, and thus i can continue on my merry way enjoying all the +ve's LR4 offers for new image imports?
Well, this applies ONLY to images whose PV is 2010 and whose point curves were modified in LR3 and whose catalog was updated to LR4. All of the other image settings upgrade. And for those people who have the issue, a script will be available soon to return the point curve settings...
