Knock has announced major upgrades to its developer experience, including revamped documentation and new SDKs for various programming languages. The documentation has been redesigned for easier navigation and improved accessibility, now catering to both human users and large language models (LLMs) with features like static Markdown pages and a RAG API endpoint for querying. The new SDKs for Node, Python, Go, Java, and Ruby are now fully typed and include features such as retries, auto-pagination, customizable logging, and configurable timeouts, with future plans for PHP and .NET SDKs. The updates are powered by the OpenAPI spec, ensuring that API changes are seamlessly reflected in documentation and SDKs, enhancing both the Knock team's workflow and the overall developer experience.
