ddclient and Cloudflare (API v3 deprecated)

[Lorenzo]

I have installed ddclient 3.8.3 on my Raspberry Pi 3.
I have modified my /etc/ddclient.conf to include the following:

protocol=cloudflare
use=web
server=www.cloudflare.com
ssl=yes

login=xxxxxx@gmail.com
password=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

zone=xxxxx.com
xxxxxx.xxxxxx.com

But the update does not work as it seems the API used by ddclient to communicate with Cloudflare have been deprecated. This is the message I receive when I run sudo ddclient -daemon=0 -debug -verbose -noquiet:

Am I doing something wrong or just ddclient needs to be updated to work with Cloudflare's new API?

The fresh v3.9.0 should fix this issue.
