This is especially useful for storing and retrieving messages with a message payload size greater than the current SQS limit of 1 MiB, up to a maximum of 2 GB. Specifically, you can use this library to:
 
-* Specify whether message payloads are always stored in Amazon S3 or only when a message's size exceeds 256 KB.
+* Specify whether message payloads are always stored in Amazon S3 or only when a message's size exceeds 1 MiB.
 
 * Send a message that references a single message object stored in an Amazon S3 bucket.
