One serious heads up for those of you planning to install 7. Bins opened or created in 7 can ONLY be opened in the most recent versions of 6 and 6.5 (being 6.0.4/10.0.4 or 6.5.3/10.5.3 or later). So if you regularly go back and forth between older systems, or if you need to create bins that others are going to need to use, you will need to keep this in mind.
I will be taking a 6.5 project from the US to a 7.0 system in europe soon. Is the forward compatibility an issue. I will be taking the entire project and media for finishing after some final editing in 7.
