Features and Improvements
- Auxiliary Files (SCRIPT and DATA Sections): Added script command RegionLoadShapeFile to load regions directly from a shapefile.
 - Auxiliary Files (SCRIPT and DATA Sections): Fixed bug merging buses. We were assuming the bus being merged was the from bus of a incident line to be moved. This wasn't always true, and could cause problems like disappearing 3-winding transformers.
 - General: In the Connections Menu there is a new dialog called Find Phase Shift Groups. This shows the user all the case phase shift groups, and has an option to remove the groups.
 - Transient Stability: This was a bug in the script command TSPlotSeriesAdd that was not applying the filter correctly. This bug was fixed and now the filter is applied correctly.
