Release 1.2.1

Greater memory efficiency at runtime to allow even more complex applications on Safari, whether on iPhone, Mac, or Apple Vision.

LZ4 Supercompression 

UASTC textures are now supercompressed with LZ4, which balances decoding speed, binary size, and compression ratios.

Streaming into WASM memory 

We now stream binary data into WebAssembly memory, which greatly improves peak memory usage and paves the way for loading directly from streaming requests in the future.
