there is one new feature in the new v5.0.0 which was missing from the early release notes, but that which some people might have an interest. the Van Essen Lab created some ROIs on their PALS-B12 atlas, and then mapped them to the freesurfer fsaverage subject. some basic info is here:

http://surfer.nmr.mgh.harvard.edu/fswiki/PALS_B12

it will take a bit of freesurfer expertise on your part to make use of these, as you would need to:

1) identify which labels (ROIs) are of interest to you (by viewing the .annot file on fsaverage) 2) use mri_annotation2label to extract the labels 3) use mri_label2label to map from fsaverage to your subject 3) optionally use mri_anatomical_stats to get stats about those labels
