- The limit for text entry in certain combo boxes has been removed
- Basic XML graph saving support has been added (only filters and connections at the moment)
- Pins are now referred by their indexes in XML rather than by ambiguous names
- Added command-line /render parameter, which loads a graph, plays it and exits
XML support and /render allow scripted generation and rendering of XML graph files.
Update: Check out GraphStudioNext. Some or all of my patches have been merged into that project, and presumably will be in the next release (the one after 0.5.0.1).
