7.4.1 - 11 Feb 2019
- Fixed correctly using first DEM surveys cell size when adding subsequent DEMs to project (#341).
- Fixed correctly reading associated surface type from GCD project XML file (#343).
- Deleting inter-comparisons now working (#332).
- Removing the ability to use an associated surface raster as an error surface (#329). Users should simply add the existing raster as an error surface directly.
7.4.0 - 6 Nov 2018
- Fixed issue when attempting a linear extraction with ShapeFiles containing null and multipart geometries.
- Raster properties now appear in the correct raster units instead of always being converted to meters.

Toolsmenu in the Standalone to
Customizeto be consistent within the ArcGIS AddIn.
7.3.0 - 14 Sep 2018
- Bug fix to user FIS library loading
7.2.0 - 27 Aug 2018

- Budget Segregation
- Budget segregation results screen now includes graphs showing the overall breakdown of surface raising and lowering for all classes.
- Fixed order that classes are displayed when the budget segregation is performed using a directional mask.
- Generic batch tool now allows user to select both surfaces and uncertainty method for each batch.

7.1.1 - 29 Jun 2018

North Arrow Research Ltd.

7.1.0 - 11 May 2018
This one is a big release that changes the platform of the Standalone so if you have the Standalone installed you will need to uninstall it and re-install it. Further updates should happen as usual.
Nearly 50 bug fixes and enhancements including:
- 64-bit support! (Standalone only) We’re thrilled to announce the Standalone product is now working in full 64-bit.
- Memory leaks: Fixed a nasty memory leak issue which should free up more RAM and allow for larger rasters to be processed.
- Significant performance increases (in addition to the 64-bit) when doing windowed operations like Hillshading.
- Lots of workflow issues to smooth out user experience.
- Many file locking issues.
- Dozens of little UI glitches and typos.
- Better help and tooltips overall.
- Improved integrity checking when deleting project items.
- Morphological analysis results and user interface still being finalized.

- Fixed y axis label when switching between area and volume DoD histogram plots.
- Enforces zero as the minimum of the elevation change DoD bar charts.
- HTML encoding GCD project file path when exporting to the Cross Section Viewer (allows for spaces in the path).
