On Monday, March 3rd, we released Sonar Standard Edition in conjunction with SharePoint Conference 2008. Sonar Standard builds upon the success of Sonar Lite by adding features requested by enterprise customers, including server control metrics, improved sorting and filtering capabilities, security trimming, and compatibility with Office SharePoint Server 2007 publishing pages.
Sonar Standard (MOSS and WSS) is priced at $499 per server. Sonar Lite (WSS) is still free. Contact Sales for more information.
The full press release is here (and the official joint release with Microsoft is here).
