Sep 1, 2025September 2025 (Azure/azure-storage-azcopy) focused on reliability, security, and forward-compatibility. Delivered multi-process AzCopy detection with stale PID cleanup, a dedicated --check-version flag for explicit version checks, and a security and compatibility package that reduces risk in production deployments. A patch release (10.30.1) addressed operational gaps (exclude-path handling, concurrency, JSON output for warnings, latest_version.txt creation) and fixed a nil pointer dereference during sync, while upgrading the Go toolchain to 1.24.6. Implemented redaction of sensitive credentials in logs (x-amz-credential) to strengthen data security. Added backward compatibility fallback logic for token retrieval with older Az.Accounts, with guidance to upgrade for improved security. Overall, these changes improve stability, security, and ease of use for automation and enterprise deployments.
