Version 0.13
Version 0.13 includes the following new functionality:

• First version of the software to support fetching a heap dump. To use, click the Heap Dump icon on the toolbar. Then do something with Mozilla (move the mouse). The reason for this is that currently we fetch the heap in the context of the currently executing code and we need an event from the JavaScript engine to do this. We hope to improve this in future versions. After moving the mouse, the event will be processed, there may be a small pause (depends on how large your application is) then data is sent to the JSMV user interface. Use the References tab to see the results. Any errors whilst fetching the heap dump will be reported on the Diagnostics tab. Now that this work is complete we can move on to more interesting topics such as "Path to Root" which some of you have asked for.
