Loadster 3 (previous version)
- Adds a new “Support Request…” option to the Window menu of Loadster Workbench to automatically submit a support request with application logs.

- Fixes a bug in the test reports, related to calculating network throughput and total bytes transferred in tests with multiple populations ending at different times.
- Adds the ability to toggle chart series visibility by clicking on them in the legend.
- Adds Server Name Indication support for connecting to the cloud services. In the next couple months we may migrate the Loadster cloud services to use SNI which will break compatibility with older versions of Loadster Workbench.

- Fixes an error with loading test reports for users storing their projects in the cloud.
- Fixes a possible memory leak in the Loadster Engine.
- Changes the garbage collector for more effective memory management.

- Adds the ability to use a web proxy from Loadster Engine when connecting to the licensing server.
- Fixes a UI bug with the graphical script editor that occurred when dragging to resize the script logs panel.
- Improves UI performance of the script editor.
- Adds the ability to delete old script results by right-clicking their timestamp in the script editor.
- Reduces the footprint of on-disk temp files when running load tests, to save disk space.

- Adds a new option to limit a virtual user group’s total iterations (exiting early once the total iterations have been reached, even if there is time remaining).
