Ah, that might be a mistake then, changes should be:

1. Et al used for more than 2 authors.
2. Last name no longer in all caps
3. Comma included in citation- ie (Smith 2008) now becomes (Smith, 2008)
4. No inversion of initials for 2nd author, eg KANE, M. and W. TROCHIM will be Kane, M. and Trochim, W.
