Invoice line items now have unique IDs and can't be used in place of a subscriptionBreaking changes
What’s new
The id field of invoice line items of type=subscription can no longer be interpreted as a subscription ID. It’s now a unique invoice line item ID, which you can use for pagination.
Impact
This change alters the meaning of the id field for subscription-type invoice line items, making it a unique identifier for the line item itself rather than a subscription ID. You can now use this id for pagination purposes when working with invoice line items. This might require updates to existing code that relies on interpreting these id values as subscription IDs.
