CoovaChilli 1.6 on OpenWrt 19.07.7

Hi,
is it possible to install the new CoovaChilli Version on the Openwrt 19.07.7 version? The last package is 1.4, right?
Thanks a lot

Yes.
However, I (still) prefere to use the old, org version 1.3 .

Please mind: OP is asking about v1.6, not 1.4.

I still see 1.4, not 1.6: https://openwrt.org/packages/pkgdata/coova-chilli
