Contributions summary:Dennis primarily contributed to enhancing the functionality and maintainability of the Shopify Buy SDK. They added a new `available` field to the variant query and fixed the image resize helper to handle images without query parameters. Further work included the implementation of backwards compatibility support for older client configurations and features like fetching products and collections by handle. This suggests a focus on API enhancements and improving the SDK's usability.
