Have I received old TRVs?

Options

I've just purchased 16 Tado TRVs. The boxes I received look a bit old and I'm wondering if I've received old kit. But then, maybe there is no difference between old and new Tado TRVs?

On one of the "Quattro Pack" boxes there is a sticker on the side with the following numbers/codes:

V3P-4SRT01V-TC-ML-00
