Any differences between 37mm 3.5m Hose 204924 and 500681

[gwendal]

What are the difference between these 2 products:

Festool 204924 Braided Sleeve Antistatic Hose, 36mm X 3.5m AS/CTR
Festool 500681 Braided Sleeve Antistatic Hose, 36mm X 3.5m

Why did the product number change?

From the description at festool-products but not at festoolusa,
there is a mention of a """RFID chip for automatic suction hose detection""".

How does it work?
