The SDK documentation that has until now only been available as part of the SDK installation package is now also available online!
You can find a link to it in the right-side menu of the forum or you can simply use the direct address: http://doc.developer.milestonesys.com
Same goes for the documentation for the new Mobile SDK, which can be found at this address: http://doc.developer.milestonesys.com/mipsdkmobile/
