The latest version of Flux (formerly IFQL) has been released with several new features focused on improving the language itself. The release includes support for defining and calling functions within Flux, as well as several new built-in functions such as map, shift, integral, derivative, and difference. This allows users to create small reusable components in their queries and apply logic to the records of the data using well-scoped functions. Functions are a powerful tool that can help build libraries of useful snippets over time. The release also introduces support for multiple values, with the covariance function being one of the first to utilize this feature. The new features aim to bring more power to Flux, and users are encouraged to provide feedback or suggest additional functions through open issues or pull requests on the Flux repo.
