[Stable] Changing the default backend to “sox_io” (for Linux/macOS), and updating the “soundfile” backend’s interface to align with that of “sox_io”. The legacy backend and interface are still accessible, though it is strongly discouraged to use them.
[Stable] File-like object support in both "sox_io" backend, “soundfile” backend and sox_effects.
[Stable] New options to change the format, encoding, and bits_per_sample when saving.
[Stable] Added GSM, HTK, AMB, AMR-NB and AMR-WB format support to the “sox_io” backend.
[Beta] A new functional.apply_codec function which can degrade audio data by applying audio codecs supported by “sox_io” backend in an in-memory fashion.
Here are some examples of features landed in this release:

```python
Load audio over HTTP
with requests.get(URL, stream=True) as response:
    waveform, sample_rate = torchaudio.load(response.raw)
Saving to Bytes buffer as 32-bit floating-point PCM
buffer_ = io.BytesIO()
torchaudio.save(
    buffer_, waveform, sample_rate,
