We noticed that they are now grouping all TV seasons together. In a way, it makes sense, but if you're watching a show that has seasons that have not yet been released, it might make it more difficult to know when they are available on Instant Queue, just by checking Netflix.
On the other hand, I just started watching 30 Rock
and I did find it annoying that I had to add all of the seasons to my Instant Queue. Not the end of the world, mind you, but a minor annoyance all the same.
