# Changelog

> Recent changes to the Procuros API v2

<Update label="April 6, 2026" description="Automatic cleanup of outdated document versions">
  ## Automatic Cleanup of Outdated Document Versions

  When a new version of a document is detected, any older version that is still waiting to be collected is now automatically removed from the pending queue. This means `GET /v2/transactions` will only ever return the latest version of a document — you no longer need to check `isLatestVersion` when processing pending transactions, though it remains available for completeness.

  See [Document Versioning](/en/api/v2/features-document-versioning) for full details.
</Update>

<Update label="March 21, 2026" description="Document versioning fields">
  ## Document Versioning

  New fields on `Transaction` and `ReceivedTransaction` schemas: `replacesProcurosTransactionId`, `replacedByProcurosTransactionId`, and `isLatestVersion` — allowing you to detect superseded documents and trace version chains.

  New guide: [Document Versioning](/en/api/v2/features-document-versioning) — explains how Procuros links old and new versions of the same document. All receiving guides have been updated with versioning information.
</Update>

<Update label="March 13, 2026" description="Order identifier on shipping notice line items">
  ## Order Identifier on Shipping Notice Line Items

  New field `orderIdentifier` added to shipping notice line items, allowing you to trace each line back to its originating order.
</Update>

<Update label="March 3, 2026" description="Technical sender party">
  ## Technical Sender Party

  New party `technicalSender` added to all document types. This identifies the system or party that technically transmitted the document, which may differ from the commercial sender.
</Update>

<Update label="February 25, 2026" description="Relaxed ship-to identifier requirements">
  ## Relaxed Ship-To Identifier Requirements

  Identifier fields on the `shipTo` party are no longer required, giving more flexibility when the shipping destination does not carry a formal identifier.
</Update>

  ## Receival Notice

  Added receival notice documentation. See [Sending Receival Notices](/en/api/v2/sending-receival-notices).
</Update>

<Update label="January 23, 2026" description="Pricing unit fields on orders">
  ## Pricing Unit Fields on Orders

  New fields `pricingUnitQuantity` and `pricingUnitOfMeasure` added to order line items, supporting scenarios where the pricing unit differs from the ordering unit.
</Update>

<Update label="January 22, 2026" description="Order response documentation">
  ## Order Response Documentation
