When freesurfer6.0 is released we will publish a set of brain maps for some of our internal data sets which will show the regions of the brain that demonstrate statistical differences for various measures (e.g. thickness, area) between the most recent release v5.3 and the upcoming release v6.0. Whether your data will exhibit the same trends is impossible to say. But we do make the following statement on our download page in regards to processing subjects with freesurfer: " *Important Note!* When processing a group of subjects for your study, it is essential to process all your subjects with the same version of freesurfer, on the same OS platform and vendor, and for safety, even the same version of the OS. While we continue to work to ensure that results match across platforms (for instance the 32b and 64b CentOS 4 builds should produce identical results), there are none-the-less system-level libraries that are OS dependent. An exception to this rule is that you may view and edit files across any platform or version, and run some post-processing tools (outside the recon-all stream) if you check with us first (for instance you may run the longitudinal processing with newer versions).

Yes, you can install the new version of freeview over your existing version of freeview as updates to that application, and edits made with it, should not effect to overall processing stream. Just follow the "Freeview dev version" download instructions on this page: https://surfer.nmr.mgh.harvard.edu/fswiki/Download > I cannot seem to get the 'curl -O' to download the software.
