One of the most requested features we have had is a way for MindTouch to automatically save content users are in the process of creating. Murphy’s Law teaches us that when you are hard at work on something for a very long time and you forget to save your progress, that’s when your computer will fail you. Now, in the event your browser crashes, when you get back to your MindTouch site, and navigate to the page you were working on, it will ask you if you want to continue editing the page you were working on or abandon those changes and work with some previous version.
The auto-save feature produces a notification in the editor dialog (top right corner) every time it saves. Look for it after you upgrade and start editing.
This feature is available in Core, Platform and TCS versions of 10.1 and 11.
