Clarification: it's not a question of production generation, so the 2 versions may be on sale at the same time.

It's variable, the differences are mainly the Bluetooth and Wi-Fi modules, but the functionality between the versions and the performance are identical. The only effective solution I've found to determine the version is to check the bios version. The bios don't have the same style of number, so you can't go wrong.

yes I have V1.1
