1.4.0

Version 1.4.0 release

• WASM and JavaScript decoders are hosted from a static URL.
  • It is recommended to always pull your Draco WASM and JavaScript decoders from this URL:

• Changed npm modules to use WASM, which increased performance by ~200%.
• Updated Emscripten to 2.0.
  • This causes the Draco codec modules to return a promise instead of the module directly.
  • Please see the example code on how to handle the promise.
• Changed NORMAL quantization default to 8.
• Added new array API to decoder and deprecated DecoderBuffer.
  • See PR #513 for more information.
