# Changelogs

> Track Browser SDK releases — version history, fixes, and new features

We document all notable release changes to the Browser SDK on this page. We base the format on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## Release Process

We release all changes to beta first before updating to a stable release at least two weeks later, and we update all changes on this page. All past releases are URI accessible from links below and immutable, unless explicitly stated.

You can [subscribe](/sdk/client/browser/changelog/#subscription-section) to get notified of all changelog updates via `email` or `RSS feeds`.

## Browser SDK V2.1

### Version [v2.1.36](https://cdn.plivo.com/sdk/browser/v2.1.36/plivo.min.js) Dec 10, 2020

#### Bug Fixes:

* **Fixed**: Incoming calls were not ringing in desktop browsers or when the tab with the call was in the background. While this is the expected behavior in mobile browsers, it should not occur on the desktop.
* **Fixed**: Ongoing browser calls faced a one-way audio issue (remote user unable to hear the browser app user) if the Bluetooth audio device being used by the browser app user got disconnected and switched to another audio input device.

### Version [v2.1.36-beta.1 (Beta)](https://cdn.plivo.com/sdk/browser/v2.1.36-beta.1/plivo.min.js) Nov 25, 2020

#### Bug Fixes:

* Fixed: Issue where incoming calls were not ringing in desktop browsers as well when the tab with the call was in the background. This is the expected behavior in mobile browsers but not desktop ones.

### Version [v2.1.36-beta.0 (Beta)](https://cdn.plivo.com/sdk/browser/v2.1.36-beta.0/plivo.min.js) Nov 20, 2020

#### Bug Fixes:

* **Fixed**: Issue where an ongoing browser call would face a one-way audio issue (remote user won’t be able to hear the browser app user) if the Bluetooth audio device being used by the browser app user got disconnected and switched to another audio input device.

### Version [v2.1.35](https://cdn.plivo.com/sdk/browser/v2.1.35/plivo.min.js) Nov 19, 2020

#### Bug Fixes:

* **Fixed**: Issue where client name was being sent as "Chrome" as part of Call, Answered, and Call Summary events even for calls made from Microsoft Edge browser. Now the value sent will be "Edge."
* **Fixed**: Issue where setting the configuration parameter "dscp" as true was not behaving as intended and all UDP packets were still being set with DSCP Class CS0 (default class) instead of DSCP class EF (Expedited Forwarding), which is the expected behavior. Being set with EF ensures packets being tagged as high priority by network routers, leading to lower chances of these packets being dropped and minimum per-hop delays.
* **Fixed**: Issue where on receiving an incoming mobile browser call with the browser in the background, the phone would start ringing despite a visual notification not possible (due to limitations imposed from browsers) and the customer having no way to find out which app is making the phone ring. Now the phone won’t ring either.
* **Fixed**: Issue where a "TypeError" was being emitted if audio devices were toggled during an ongoing call. While this error did not affect any functionality, it was unnecessary and hence will not be emitted anymore.

### Version [v2.1.35-beta.0 (Beta)](https://cdn.plivo.com/sdk/browser/v2.1.35-beta.0/plivo.min.js) Nov 06, 2020

* **Fixed**: Issue where a "TypeError" was being emitted if audio devices were toggled during an ongoing call. While this error did not affect any functionality, it was unnecessary and hence will not be emitted anymore.

### Version [v2.1.34](https://cdn.plivo.com/sdk/browser/v2.1.34/plivo.min.js) Oct 19, 2020

#### Bug Fixes:

* **Fixed**: Issue where onConnectionChange event was not getting triggered in the following scenarios:
  * normal endpoint logout
  * abrupt socket disconnection due to changed network conditions
