Google released a new version of its Google Analytics tracking code in December 2007. The new tracking code is referred to as "ga.js"
The new tracking code is a complete rewrite of JavaScript inherited from Urchin analytics. This is the first time the two products have been decoupled. The previous version of the Google Analytics tracking code is referred to as "urchin.js", and it is suppose to work until the end of 2008.
Going forward, Google will only release new features on the new "ga.js" tracker. Therefore, it is recommended to upgrade your tracking code to the new version.
What's new?
- The new Google Analytics tracker supports proper JavaScript name spacing and intuitive configuration methods.
- Some test shows that it has a faster execution while the size of ga.js is minimized.
- Makes advanced features a lot more accessible.
- Track a page on multiple Google Analytics accounts.
- The new event tracker lets you segment a set of related actions.
