The OpenX Blog and an e-mail newsletter to all registered users have been announcing the newest installment of the OpenX Ad Server software, version 2.8.4 for the last 6 days. Yesterday, the new version has finally been released for download.
I have been able to test this new version in recent weeks, and I can report that the installation and upgrade procedures have been changed significantly. One very important change is that anyone installing or upgrading is forced to create an OpenX account. This used to be optional. In my opinion, this will put off a lot of users from upgrading or from even starting to use the software. The software is still free of charge, but users now pay a price by having to give up their privacy.
Update January 31: A bug has been found in OpenX version 2.8.4, affecting the display of statistics for banners. It appears to be mostly a cosmetic problem, the statistics are in the database but not showing up correctly in the OpenX statistics screen. Information can be found on the OpenX Developer Site.
