The change I'm really excited about in GA is flow visualization:
Flow Visualization was announced in October, but only recently started rolling out to most users. Flow Visualization consists of two reports: Visitors Flow and Goal Flow. The Visitors Flow report can be used to visualize the “flow” of visitors through the site, while the Goal Flow is an improvement on the original Funnel Visualization reports.
The Goal Flow report is especially valuable, as it simplifies evaluating a conversion funnel. Have a checkout process six pages long? Now you can determine at which page people are abandoning their carts. Then improve the process and save the sales.
