The latest version of Draco brings many new enhancements to improve the development experience: * Stable API release * Support for npm Javascript package management * Javascript based encoder * Generalized metadata for meshes and point clouds * Now supporting material properties included along with encoded file * Improved compression rates: * 15% better compression on smaller models * 40% better compression of normals * Performance improvements (~10% faster encoding, decoding) * Reduced GPU memory usage: * Option to store decoded quantized attributes * Support for triangle strip connectivity on decoded meshes * iOS 9 Javascript decoder * Bitstream specification now available
