Old API being discontinued?

Noticed this in the What's New:
We've been developing the beta portal for a little over half a year now and we think that we're getting to a point with it where we're almost ready to remove the legacy portal entirely and replace it with the new one. This means our old APIs and user interface will be taken down and this new portal will sit in its place. We're not doing it yet, though! We'll give at least 1 month's notice beforehand.

@Mickey (GivEnergy) could you confirm which ones specifically will cease (presume all of them) and I guess would just leave the Battery API standing? Also assume that the API Key from the old portal will be accessible from the new somewhere - The one you generate in the Beta Portal has yet to work for me on the battery API so I've always had to exchange the old one as part of the "Signup" process to date.

So to anyone using the older style API, once above is confirmed you may want to think about transition to the newer Battery API (which doesn't just do the battery contrary to it's name!) before hand.

We're giving users considerable time to access a new set of APIs, which is hopefully coming soon and will be hosted on our api domain. We've always had issues with how the old APIs were developed so with our new portal, we have the resources to give it a complete overhaul so everything including the battery api and the old api endpoints will be migrated before we remove them.

It's not going to be a simple process. And so we will be informing our customers of this change when we've released this new feature to use

That's fine, this was more for people who may not necessarily have read the "What's New" part as they have it all in Home Assistant or something and don't use the portal!
It needs doing, some stuff is doubled up & the way you access certain ones and not others is always a pain.
Thanks for your efforts on the API stuff to date!
