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

Some key features of 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.

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