Earlier in the week, OpenX version 2.6.3 was released. This upgrade is all about fixing bugs and introducing small enhancements. The OpenX blog has a link to the release notes and there is also a list of the 80+ changes that are part of this upgrade.
I’ve done a dozen upgrades from earlier versions to this one over the last few days, and the upgrade process is pretty smooth, since there are no changes in the database structure this time (unless you’re coming from OpenX 2.4). In any event, it’s always a good idea to follow a proven procedure for OpenX upgrades. If you’re interested, I can also do the upgrade for you. Check out my support request form.
