HDMI 2.0 supports 4K @ 60hz, HDMI 1.4 supports 4K @ 30hz, the title and the description mentions both - which one is correct?

The Mini DisplayPort to HDMI Adapter supports HDMI 2.0, which allows for 4K resolution at 60Hz.

The title says HDMI 2.0 but in the description it says "Side 2: HDMI A Female Port which supports v1.4" so I have to ask - is it 2.0 or is it 1.4?

The description specifies that the HDMI A Female Port supports version 1.4, despite the title mentioning HDMI 2.0.
