FOSSBilling releases v.0.10 stable version which is a fork from Box Billing that has not been supported for many years now.
It will be good to have CyberPanel supported which the developers do not want to add to core modules.
CyberPanel been available on FOSSBilling will increase publicity and usage and since it is a promising replacement for WHMCS it will see a lot of users soon.
Maybe the CyberPanel Developer @usmannasir or anyone from the community will like to pick this up.
Someone started one already Repository
