Release Notes

Add Ferdi API to Ferdium hosted services.

[vraravam]

I see a lot of hits in Login.js, AccountDashboard.js and other files if I search for LIVE_FRANZ_API - don't they also need to accommodate the new constant?

[SpecialAro]

Maybe. I can try to give it a look for the rest, although I'm not entirely sure they will be needed.

I tested the current code with Account Creation and Login to the ferdi API and it worked, at least.

please also ensure that all paths of code that use the apiBase.js are also tested. for eg, Help > Import/Export Configuration Data opens the browser in specific url
