Last updated: November 29, 2024 # API & jQuery SDK 2.3.0 enhancements announced ![Tim Koschützki](/assets/images/teammates/avatar-tim-kos-1.jpg?dpl=dpl_6nhQNS5wkVkPZWuKMzXcWrAHNJL5) **Tim Koschützki** Co-founder · Berlin, Germany · Show bio [](https://x.com/tim%5Fkos)[](https://github.com/tim-kos) Today, we would like to announce a few changes to our API, as well as a brand new version of our jQuery SDK: * We have removed the `calc_md5_hash` parameter from all Robots and the`calc_md5_hash_for_uploads` parameter from the general API params. Please remove them from yourTemplates and params, as they no longer have any effect. Instead, we are now calculating the MD5-hash for all uploads and all conversion results by default! We have also added a new Assembly Variable called `${file.original_md5hash}`, which tracks the MD5-hash of the original uploaded or imported file of which the file you are looking at is a descendant. You can use these MD5-hashes to track duplicate file uploads. * Files that are imported through the [/http/import](/docs/robots/http-import.md) Robot now track the `import_url` in their metadata. This makes it easier for you to map conversion results back to the original imported file. * We have released version 2.3.0 of our [jQuery SDK⁠](https://github.com/transloadit/jquery-sdk), which contains a few fixes and improvements. For example, progress bars can no longer exceed the 100% mark if you also load Twitter-Bootstrap's CSS. Furthermore, we have fixed the majority of connection errors to API endpoints, which were occurring from time to time. By the way, we are also going to introduce a new development SDK and support for HTTP Live Streaming (HLS) very soon in two separate posts, so please stay tuned! Have a great weekend everybody!
