2015 version of HP12c identification

[Dol]

Hi I presume there is a 2015 version of the HP12c with dual CR2032 batteries.

I already have a 25yr anniversary platinum with a singles cell battery and dislike the buttons and the display.

If I order from Amazon, how do I make sure to get the greatest and latest 2015 model with the latest CPU? Does anyone have a part number for that?

I don't want to order and risk getting a 2003, 2010 etc vintage. I have already ebayed home a few 10 USD random models and only look for the latest.

If anyone with a 2015 model could compare the buttons with the 25yr platinum which I feel are a bit hollow I would also be happy.

Regards,
Fredrik
