Information on what's new in ntfs-3g can be found at the NTFS-3G release page.
The only OS X-specific change for this release is how the new dialog boxes appear when a mount has failed. The new method will hopefully not block the Finder (I have had reports on the Finder locking up with inconsistent NTFS drives, though I haven't been able to confirm it), or make the startup screen go nuts after displaying an error message before login.
