Backstage Blog May 1st, 2014 Announcements JavaScript SDKs Introducing JavaScript SDK version 2 By Erik Michaels-Ober

SoundCloud is pleased to introduce a new major version of the SoundCloud JavaScript SDK. In version 2, we've rewritten much of the internal code, resulting in better performance for your JavaScript applications and support for more streaming standards, such as HTTP Live Streaming.

You can test the new version by pointing your JavaScript applications to http://connect.soundcloud.com/sdk-2.0.0.js.

We've also created a guide to help you upgrade from version 1 to version 2.

JavaScript SDK version 1 is now deprecated and will be permanently replaced by version 2 on July 1, 2014.

On June 17, 2014, we will temporarily replace version 1 with version 2 between 10:00 and 11:00 UTC. We will do this again on June 24, 2014, between 18:00 and 19:00 UTC. These two upgrade tests will give you an opportunity to understand the impact of this change on your applications. To ensure a seamless transition for your users, we strongly encourage you to upgrade and perform internal tests in advance of these dates.

To receive notices before, during, and after these tests, follow @SoundCloudDev on Twitter.

If you have any questions about this upgrade, please feel free to email api-support@soundcloud.com.
