NOTE: If upgrading from an earlier beta release of the ad module, you must run update.php as there was a schema change in -beta3.
What's new: filter adserve input to prevent XSS attacks; can schedule ads to be automatically enabled or disabled at a certain time; can schedule ads to be automatically disabled after a configurable number of views or clicks; support for displaying multiple ads (also built into auto-generated ad blocks); improved ad status messages when viewing ad nodes; a proof-of-concept ad_report module for basic gd-generated graphical reports; improved support for PHP4; improve path handling to allow ads to be used when Drupal is hosted in a subdirectory; various bugfixes.
