Update from 4.11 to 4.17 no radiolan.npk in zip file

Hello,

I want to update my router from 4.11 to 4.17 and I have the radiolan package installed too.

But the radiolan package isn’t in the 4.17 zip file (All packages, X86).

Don’t I need it anymore ? What is this package for ?

best regards

Carsten
