Cloud Storage SDKs enable end-to-end checksumming by default

Cloud Storage SDKs now enable end-to-end checksumming by default, building on server-side CRC32 validation and object checksums. This reduces the work needed to detect data corruption across uploads and downloads.

What: Cloud Storage SDKs now enable end-to-end checksumming by default to help protect data integrity.
How: SDKs calculate and send upload checksums when applications do not provide them, and support checksum verification on downloads and range reads.
Why it matters: Automatic checksumming helps detect data corruption across application-to-storage transfers without requiring applications to implement it themselves.

The SDK adds a checksum to application data before sending it to Cloud Storage. Sketched from the article's own text.
