The "rilles" which appear to be new are located at the origin of the jet.
Also the dark "smear" to the left of them seems to be more prominent now.

"The latest Navcam blog shows new - or apparently new - features in the neck. Here's a comparison between October and December images (December on the right). I would suggest a close examination of images would probably show more things like this.
