Module: Google Analytics 
Author: Mike Carter <www.ixis.co.uk/contact>

WARNING: If you upgraded from Google Analytics 1.3 or before you must
check your "Page specific tracking" settings at
admin/settings/googleanalytics. If not set properly Google Analytics
may begin tracking different pages than you intended after upgrading.

Beginning with Google Analytics 1.4 the logic for when to include the
Google Analytics code on a page has been reversed. In 1.3 and before,
roles were were checked in checkboxes to exclude Google Analytics from
counting pages when users with those roles were logged in. Beginning
with 1.4 those same checkboxes are used to include the tracking code
only on pages for the roles checked. If no boxes are checked, the code
will be placed on all pages. The new functionality has been built on
the model of how block visibility is set in Drupal core.

Note that with the new system you must write custom php code if you
want to track pages for authenticated users who have no specific role
set and also exclude other authenticated users who do have a specific
role. Clicking on the "authenticate user" role checkbox will
automatically cause the tracking code to be written for all logged in
users. Version 1.4 provides the possibility for including custom code
to get the precise tracking you desire should you need it.
