Contributions summary:Gannon primarily contributed to the IdentityCache library by adding support for embedded associations, specifically for has_one and has_many relationships. Their work included modifications to the query API to handle cached associations and the introduction of new cache key generation methods, facilitating efficient data retrieval. They refactored the codebase to utilize dedicated objects for association options and prefetching, along with improvements to cache key hashing, enhancing the library's performance and functionality.
