🚨 Breaking Changes 🚨

• Updates the unique_invoice_line_item_id uniqueness test in stg_stripe__invoice_line_item to include invoice_id. This is because unique_invoice_line_item_id (unique_id in the raw source invoice_line_item table) was part of an older version of Stripe that was included in the new version to help migrate internal references. See the Stripe API update for more information. The Fivetran connector persists this in order to resolve the pagination break issue for invoice line items that was introduced by the API update.
