Google Analytics JavaScript Tracking Code Changelog

Subscribe

We periodically update the Google Analytics JavaScript Tracking Code (ga.js) in order to deliver new features and to repair defects discovered in previous versions.

This page documents any changes made to ga.js. We recommend that developers periodically check this list for any new announcements. Changes will also be announced via this page's Atom feed.

Note that you and your users may not see the updated ga.js right away because:

• Changes are incrementally rolled out over several days across Google's global data center infrastructure.
• Users of your website may temporarily have older versions of our javascript cached in their browsers.

Release 2009-12 (December 1, 2009)
