Nodogsplash version is old

I have AR750 which is up to date (3.2x I think).
The version of nodogsplash seems to be quite old (1.02-3).

The latest nodogsplash is 5.0.

Can we get the version delivered by GL-INET updated to the latest?

I was trying to follow the nodogsplash docs to setup a captive portal using example in their docs with binauth and username and password. I could never get the auth script to run. I think it may not be an available feature in the old version delivered OOTB.
