Magento Professional Edition is out, an attempt to fill the gap between the free Community Edition and the more expensive Enterprise Edition. It comes with warranty, support, and a few nice features like rewards points, gift certificates, and other revenue boosting modules installed out of the box, at a much cheaper price point than Enterprise (from $US2,995/yr for Professional vs $US12,990/yr for Enterprise). It lacks some  enterprise features such as sophisticated permissions, extra security features, etc, but will meet the needs of many store owners who need a supported solution but can’t afford the enterprise license.
