Cube Core v0.34.0 to v0.34.34 introduces significant updates, including Python support for configuration and data modeling, enhancements to data modeling, APIs, and SDKs, and a fix for a security vulnerability that could lead to a denial of service attack. The update also addresses issues related to views and pre-aggregations and introduces support for metadata parameters in cubes and views, offering more flexibility in exposing metadata through the REST API. Additionally, pass-through authentication has been added to the SQL API, and there are improvements in front-end SDKs, allowing for conversions of numeric types to JavaScript Number type, along with Ivy support in the Angular SDK. Users are encouraged to upgrade to prevent service disruptions and take advantage of these new features, and the Cube community is invited to share feedback and participate in future developments.
