JavaScript SDK v3 Beta

We have released JavaScript SDK v3 - a lightweight, efficient, and optimized version of the RudderStack JavaScript SDK v1.1.

Some benefits of using this SDK are:

• Smaller size of around 25KB (reduction of approximately 30% from the previous version).
• Fast, reliable, and less vulnerable to adblockers.
• You can now load specific SDK features by leveraging the SDK plugins.
• Lightweight storage footprint with improved data encryption technique.

The SDK v3 is currently in beta. See Breaking changes before you start using it.

See the JavaScript SDK v3 documentation for more information on using the new SDK.
