Version 1.0.0 (2011-09-30)
- Added Trace Viewer plug-in
- Fixed bug to set the configured block size in both directions

Know issues 
1. Problem: On dual IP stack (IPv4/IPv6) computers, it is possible that the client gets a 'connection refused' message when attempting to connect to the server. This is due to the dual-stack capabilities of Java, that make the server listen on the IPv6 address while the client tries to connect to the IPv4 equivalent. 
   Solution: Set the java.net.preferIPv4Stack or java.net.preferIPv6Stack properties when launching both the server and the client. 
2. The GUI is stuck with the progress dialog if it runs out of space while downloading traces 

Version 0.9.7 (2011-04-01)
- Fixed bug in IMBE block size. New results show lower link utilization
- Improved memory management (use of swap files when memory limit is reached)
- Fixed memory leak issues from the use of Window/Dialog objects
- Fixed various improper behavioral bugs for the Audio Trace Generator
- Updated trace format
- Added contextual help in most panels
- Additional error handling (out of memory, out of disk space, read-only directory, etc...)

Know issues 
1. Problem: A project using a user-added map cannot be moved to another computer. 
   Description: The image of the map is currently stored with the GUI so it will be missing on the other computer. 
2. Problem: On dual IP stack (IPv4/IPv6) computers, it is possible that the client gets a 'connection refused' message when attempting to connect to the server. This is due to the dual-stack capabilities of Java, that make the server listen on the IPv6 address while the client tries to connect to the IPv4 equivalent. 
   Solution: Set the java.net.preferIPv4Stack or java.net.preferIPv6Stack properties when launching both the server and the client. 
3. Problem: An error can occur when an SU connects and disconnects from its serving during an active call. This error does not occur when the SUs are roaming.
