When is the release date of the Sandisk Extreme Pro USB 3.1 Drive?

I am participating in a competition where I have to write a detailed review post of an electronic device, and the judges examine the quality of the review post.

However, rules in the competition strictly states that I can only write reviews of devices  whose release date is October 2017 or later.

I recently bought a  Sandisk Extreme Pro USB 3.1 Drive , and I hope to write a review about it, but I have no idea when the product was released. I figured out that there was a USB 3.0 drive with a different color, but I still have no idea about the release date of the USB 3.1 drive.

This is the product website: https://www.sandisk.com/home/usb-flash/extremepro-usb

Any ideas?
