I don't know what year, sorry. I think more recently bc i got it from another mom in a bundle including tommee tippee bottles which are newer. I have the box,I'll look at it in the morning to see if it says.
I was able to find the pic of the original box(from when i bought it from the other mom) and it does have the yellow circle with BPA FREE on it- so yes, it is BPA free! i'll add the cropped pic of the box if i can- it is hard to read, but when you look at other ones online, the yellow circle always says bpa free :)
