- Everything I had previously written about FSL is now obsolete, and you were a fool to read it; and
- There have also been changes to processing anatomical datasets, field maps, and independent component analysis, which look interesting. Interesting, as in, I don't completely understand all the changes they made, but they look impressive.
I haven't had much time to sink my paws into it, but it looks similar to FSL 4.x. More details to come.
