When did Canon switch to the new grey/black style lens boxing?

I was looking on the local Craigslist and noticed the same lenses with different boxing for sale and it got me thinking. I already knew the grey/black boxing is the recent of the two (white and red) but was curious if anyone knew when the change came about? I tried googling with no luck.

Thanks.

A few years ago. My (now sold) 16-35/4L IS came in a grey/silver box already.

Canon switched to the new grey/black style lens box in late 2013.
