 - `update_document` accepts a `uri` argument to change a document's URI.
 - docling-serve requests fail over to another instance on transport/5xx errors and skip instances whose circuit breaker is open; tune via `providers.docling_serve.max_attempts` and `providers.docling_serve.circuit_breaker`.
 
+### Fixed
+
+- Concurrent ingestion of the same URI no longer creates duplicate documents; the URI is re-checked under the write lock and a colliding create becomes an update.
+
 ## [0.63.2] - 2026-07-03
