Cube has released Playground 2.0 in Cube Core, allowing data professionals to build and validate their data models by executing queries and previewing results in a BI-like interface. Additionally, Chart Prototyping is now available in Cube Core, enabling users to create a minimal front-end application that queries Cube via its REST API and visualizes data on charts. Playground 2.0 and Chart Prototyping are available starting from v0.36 of Cube Core.
