What changed

How something you were already using works now, what it did before and why it changed.

What changed: your country and your prices

Your country is now asked for before you use your account, and it decides which prices you are shown without ever changing your subscription.

What changed: unpaid usage and your balance

A usage charge that cannot be collected is no longer retried for ever; after fifteen days it joins the outstanding balance of your account, which you settle once.
