I've done a couple over the years. The last version of Carrara improved the core functionality (like render times) of the program but didn't really add much 'new' to the program so I didn't do a new one for v8. 

Choose whatever suites you. Plus I have a bunch of advanced tuts on my site – and haven't made any new ones recently. I'll have to play again...
