0.23.0 verified Fri May 01 auth: no python

pip install boto3-extensions

Common errors

error ModuleNotFoundError: No module named 'boto3_extensions' ↓

cause Library not installed or installed under a different name.

fix

Run pip install boto3-extensions and ensure import uses underscores: import boto3_extensions.

error TypeError: S3MultipartUpload.__init__() missing 1 required positional argument: 'key' ↓

cause Using old API with only bucket name; new version requires key argument.

fix

Update instantiation: S3MultipartUpload(client, bucket, key)

Warnings

breaking In v0.23.0, the S3MultipartUpload constructor changed from accepting a single 'bucket' parameter to requiring a bucket and key. Code written for v0.22.x will break. ↓

fix Update constructor calls to include both bucket and key: S3MultipartUpload(client, bucket, key)

gotcha DynamoDBTransactWrite requires existing DynamoDB table. Does not auto-create tables. ↓

fix Ensure table exists before using transact write operations.

deprecated The 'paginate_all' function in paginators is deprecated in favor of 'paginate' with 'all_pages=True'. ↓

fix Replace paginate_all(...) with paginate(..., all_pages=True)
