The Microsoft Windows Azure team has released the Windows Azure SDK for Node.js 0.5.4 which will be using the Node.js 0.6.17 and iisnode 0.1.19. The Node.js 0.6.17 contains a security fix against the HTTP Server Security Vulnerability detected by recently. It would be recommended to upgrade to the new version of Azure SDK for Node.js if you have already deployed any Node.js app to Windows Azure which will provide better security. The iisnode 0.1.19 provides iisnode.yml file instead of XML based configurations which can be use for setting up all iisnode settings.
