--- features: - | Added a new parameter `additional_mimetypes` to the FileTypeRouter component. This allows users to specify additional MIME type mappings, ensuring correct file classification across different runtime environments and Python versions. enhancements: - | Improved file type detection in FileTypeRouter, particularly for Microsoft Office file formats like .docx and .pptx. This enhancement ensures more consistent behavior across different environments, including AWS Lambda functions and systems without pre-installed office suites. fixes: - | Addressed an issue where certain file types (e.g., .docx, .pptx) were incorrectly classified as 'unclassified' in environments with limited MIME type definitions, such as AWS Lambda functions.
