It's a changelog, not a training manual. What's wrong with a good old fashioned ASCII text file?
Anyway, the link to the PDF changelog is broken, I just get some J2EE Runtime error spam.
Server Error in '/smarttech' Application.
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
