🎉 Introducing tag management and journal entry tagging, new reference fields for invoices and credit notes, and additional invoice and item improvements.

API operations added

• You can now create, list, fetch, update, and delete tag groups to organise your tags. Within a tag group, you can also add, update, and remove individual tags.
• It is now possible to apply tags to journal entries at the journal entry level (on the journal entry) or at the journal entry item level (on individual line items). You can also update the tags on an existing journal entry. This is currently a preview feature.

API improvements

• It is now possible to create a paymentServiceFee type settlement for an invoice. This enables recording payment service fee deductions directly on the invoice.
• dueDate is now optional when creating or updating an invoice. If omitted, the due date is automatically calculated from the customer's payment terms.
• projectReference, buyerReference, and contractReference are now available on invoices. These fields can be set when creating or updating an invoice and are returned when fetching invoices.
• projectReference, buyerReference, and contractReference are now available on credit notes. These fields can be set when updating a credit note and are returned when fetching credit notes.
• bookkeepingAccountNumber is now supported on items. You can set it when creating or updating an item, and it is returned when fetching items.
