Apple released the 1.1 update to Aperture today and it is available for download. The price has also dropped $200 with a coupon available for those who purchased it at the higher price.
I have not had much time to work with it as I have to head to work, but the printing problem I had before is still there. (More on that in the printing forum).
Reports form the Apple forum indicate the RAW processing is now quite good. It will be interesting to see how this version works out.
