This cannot be seen in the specs listed here. V1 does not yet support 802.11be in the 2.4 GHz band. V2 apparently does. I bought my devices here three weeks ago - they are V1.0.

I bought some in November 24 with article number 36828335.
Mine are V1.

Many thanks for your answers. I was able to contact Digitec here would be the difference and for me a minimal difference that a user does not notice extremely:
V1: Signal Rate: 5760 Mbps (6 GHz) + 2880 Mbps (5 GHz) + 574 Mbps (2.4GHz)
V2: Signal rate: 5765 Mbps (6 GHz) + 2882 Mbps (5 GHz) + 688 Mbps (2.4GHz)
