This release contains experimental support of using QEMU as an emulator on browser. This uses QEMU Wasm, QEMU ported on browser.

--to-js for aarch64 containers uses QEMU Wasm as the emulator by default. x86_64 containers can also use QEMU as the emulator using --target-stage=js-qemu-amd64 flag.

Refer to examples on QEMU Wasm or on this repo(aarch64, x86_64).
