Changes in working with Amazon S3 from version 1 to version 2 of the AWS SDK for Java

The AWS SDK for Java 2.x introduces significant changes to the S3 client, including a new package structure, updated class names, and revised method signatures. While many methods can be automatically migrated from V1 to V2 using the migration tool, some require manual migration, such as listNextBatchOfObjects and selectObjectContent. Additionally, V2 replaces certain V1 classes like AccessControlList and CannedAccessControlList with new implementations.
