We started Cube as an open-source analytics framework in 2019, written in JavaScript, but since then we have made significant changes, including moving from npm to Docker for distribution and increasing our use of Rust in the codebase. Our SQL API was recently released entirely in Rust and we plan to migrate the rest of the codebase to it over time. We also plan to expand support to YAML and Python later this year. The name change reflects Cube's evolution from a JavaScript-based analytics framework to a headless BI platform, but no action is required from our customers as the change is purely cosmetic.
