> Changelog for February 11, 2026

## ✨ New Features

* **Beneficiary Document Upload:** Added new `/v1/beneficiaries/{beneficiaryId}/documents` endpoint supporting document uploads against beneficiaries via multipart/form-data content type.
* **Transaction Attachments Support:** The `/v1/transactions/transfer-payout` endpoint now supports an optional `attachments` array field for including document references with transfers. Each attachment object contains `remark` (description/note) and `uri` (document reference) fields. Multiple attachments can be included per transfer, and URIs should reference previously uploaded documents via the beneficiary documents endpoint for improved traceability.
