In case you missed it, Phase2 Technology released OpenPublish version 1.5 yesterday.
It includes the latest upgrades of Drupal modules likePanels3, cck, devel, imagecache, feedapi and mollom. And, it comes bundled with the Acquia Network module, which is a great option for support.
Version 1.5 also has two neat options for content monetization: Quantcast and Contenture. Quantcast lets publishers tag their site, analyze audience and thus get the most effective advertisements. And, Contenture provides publishers with a new micropayment system.
You can download the new version here.
