Version 0.6 of the ad module offers basic support for text and image ads. This is a BETA release.
New features: support for multiple advertisement owners; granular per-advertisement/per-owner permissions system.
Current features: support for any number of configurable ad groups; collection of comprehensive statistics allowing time-based reporting and analysis; tracking of when and where ads are clicked, by which user and which IP; an ad_image plug-in for image (aka banner) ads; and an ad_text plug-in for simple text ads.
This is a BETA release of the upcoming ad module. An official beta release will be tagged regularily as we make development milestones, or you can use this release to get the very latest code from CVS.
