Receiver can now receive chunks of data even if he wasn’t connected when the sender started sending them.
Also, some communications are added between the receiver and the sender, such as a warning when the other one disconnect, or any other form of encrypted message.
Senders were informed when they reached the max cached data limit, but are also now informed when this limit can be ignored (when the receiver download those cached data to free some space).

And the thing you can see in the demo video: it is now possible to, as the receiver, restart an entire transfer if you connect to the download, disconnect, and reconnect again (because cached data are cleaned by the backend, which mean the sender has to send them again).

I know “sender” and “receiver” are repeated 300x but idk how to explain this in a better way 😭🙏 (+ i’m french idk we’re all bad in this language tbh)
