For those willing and brave enough, another beta of v5.2.0 has been posted here for you to download and test:
ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/5.2.0-BETA/
The Mac builds should work (note: the lion build is 64b, snow-leopard is 32b).
The final release still awaits some critical improvements to the Tracula stream, but the main recon-all stream with this beta is final. The final release is expected the first week of February.
