Corona Labs has announced a big change with their 2D engine: Corona Enterprise, the native-extensions product is now free.
Starting today, developers can get a combined package that includes the standard Simulator-based product and the native-based product (formerly Corona Enterprise). And naturally, the next public release of Corona will also be a similar combined product.
