📃 May 2021 release notes

New in Chrome

The following features are now available in Chrome:

  • Accelerometer: The Accelerometer, LinearAccelerationSensor and GravitySensor APIs read the acceleration applied to a device in three dimensions, either including the effect of gravity, without its effect, or only its effect, respectively.
  • @counter-style: The @counter-style CSS at-rule sets custom counter styles for list items. For example, you can use a sequence of specific symbols instead of numbers for an ordered list.
  • JavaScript modules in service workers: The navigator.serviceWorker.register() method accepts { type: "module" } to load scripts that use import and export. Also known as ECMAScript modules or ESM in service workers.
  • Fixed-width SIMD (WebAssembly): 128-bit SIMD (Single Instruction Multiple Data) performs one instruction on multiple units of data, when running on hardware that supports such instructions. Also known as vector instructions.
