Known issues
breakingVersion 8.9.0 of the builder introduced renaming of TypeDefs: extra postfix moved to end (e.g., CreateDistributionExtraRequestTypeDef became CreateDistributionRequestExtraTypeDef). If you use type aliases directly, update imports.
fix
Update any references to renamed TypeDefs. Check the changelog for specifics.
affects: >=8.9.0
deprecatedPython 3.8 support removed in builder version 8.12.0. types-boto3-stepfunctions now requires Python >=3.9.
fix
Upgrade to Python 3.9 or later.
affects: >=1.43.0
gotchaThese stubs are auto-generated; service changes in boto3 may not be immediately reflected. If you encounter missing types, upgrade the package or report an issue.
fix
Run `pip install --upgrade types-boto3-stepfunctions`.
affects: All
gotchaThe package only provides type annotations; it does not include runtime implementations. Ensure boto3 is installed and imported normally.
fix
Install boto3 separately: `pip install boto3`.
