      "value": "The Temporal api-go library prior to version 1.44.1 did not send `update response` information to Data Converter when the proxy package within the api-go module was used in a gRPC proxy prior to transmission. This resulted in information contained within the `update response` field not having Data Converter transformations (e.g. encryption) applied. This is an issue only when using the UpdateWorkflowExecution APIs (released on 13th January 2025)  with a proxy leveraging the api-go library before version 1.44.1.\n\nOther data fields were correctly sent to Data Converter. This issue does not impact the Data Converter server. Data was encrypted in transit. Temporal Cloud services are not impacted."

Esto hacía que la información contenida dentro del campo \"respuesta de actualización\" no tuviera transformaciones de Data Converter (por ejemplo, cifrado). Este es un problema solo cuando se usan las API UpdateWorkflowExecution (lanzadas el 13 de enero de 2025) con un proxy que aprovecha la librería api-go anterior a la versión 1.44.1. Otros campos de datos se enviaban correctamente a Data Converter. Este problema no afecta al servidor de Data Converter. Los datos se cifraban en tránsito. Los servicios de Temporal Cloud no se ven afectados."
