mediasoup 3.13.20 has been released and it comes with 2 important news:

### Server side ICE consent check system

Thanks to this new feature, mediasoup can now detect abrupt client disconnections (for instance, when client’s network goes down) by monitoring received ICE consent requests sent from the WebRTC client. After 30 seconds of inactivity, the `WebRtcTransport` will emit `icestatechange` event with `iceState: ‘disconnected’.

- PR: [Add server side ICE consent checks to detect silent WebRTC disconnection by ibc · Pull Request #1332 · versatica/mediasoup · GitHub](https://github.com/versatica/mediasoup/pull/1332)
- Documentation:
  - New `iceConsentTimeout` in `WebRtcTransportOptions`: [mediasoup :: API](https://mediasoup.org/documentation/v3/mediasoup/api/#WebRtcTransportOptions)
  - Extended documentation about `icestatechange` event: [mediasoup :: API](https://mediasoup.org/documentation/v3/mediasoup/api/#webRtcTransport-on-icestatechange)

### Fix regression (crash) in transport-cc feedback generation

Critical regression that causes reliable crashes was introduced in version 3.13.18 so please update.

Thanks a lot for this change, does icestatechange triggers when ice state is ‘new’? I mean if someone attempted to create a transport and left it by accident, then it will cause a port leak

Or if someone creates a Producer or a Router or whatever by accident and leaves it open. Of course it will leaks until the parent entity is closed.
