Alibaba Cloud OSS will undergo a hot upgrade for the log management feature in all regions from 00:00 May 6, 2021 to 00:00 August 6, 2021 (UTC+8). This upgrade provides more capabilities to improve request source analysis. After the upgrade, OSS logs will display the x-oss-user-agent header. This header is appended to the user-agent field, separated by a space. This change affects the logs of access requests initiated by browser-based SDKs, while the logs of access requests that does not contain the x-oss-user-agent header are not affected. Please update your services in a timely manner to ensure service stability.
