I have a Vigor 2860 that reports current firmware as 3.8.2.2_VT3

When I "check the latest firmware" from the router web interface the pop-up suggests I may download 5 zip files:
Vigor2860_v3.8.8-00.zip
Vigor2860_v3.8.8-01v.zip
Vigor2860_v3.8.8-02v.zip
Vigor2860_v3.8.8-03v.zip
Vigor2860_v3.8.8-04v.zip

When I check the Draytek documentation page https://www.draytek.co.uk/support/downloads/vigor-2860 it links to a recommended file v2860_388_BT.zip

So I am confused which one to choose.
Any help appreciated.

v2860_388_BT.zip is the correct firmware for the UK.

I have just been told separately, that the best one to use is the one linked from the website v2860_388_BT.zip because this is the one recommended by BT (British Telecom).

So I'll give it a go.

Thanks AdrianH54, our posts crossed but you are also confirming this so that's good news
