Official version history and changelog information for Surfer (2022). 

Surfer 23.4.238 (July 30, 2022)

Improvements

• Updated licensing for security and compliance
• Updated information in the About dialog
• Legend: do not stretch text/symbol/line/fill contents when stretching legend (only adjust the margin property), and only stretch proportionally
• Profile: update automatically when replacing the source grid file

Fixes

• Assign NoData: inconsistent NoData assignment around the boundary line
• Automation: server exception when loading IMG file for relief map and Surfer became unusable
• Automation: xMapPerPU and yMapPerPU not reporting correctly after scale transforms were applied
• Bring to Front and Send to Back: Contents window needed a refresh
• Color Relief: Data limits did not update when changing from Reflectance to Color only after reload grid
• Colormap Editor: Data Value box did not update when set to a negative value and Apply was clicked
• Could create a Variogram inside a base layer
• Crash when adding empty base layer
• Crash when closing Surfer after file not fully loaded
• File | Open: some SRF files took a long time to open in v23 due to invisible color scale attached to a grid layer with a large data range
• Grid From Contours: some contours with ZLEVEL or Z Coordinate information were ignored
• Internal Error after assigning NoData to a grid using a DXF file containing polylines with collinear data (polygonutility.cpp)
• Internal Error when creating Worksheet window
• Map Wizard: the 'Entire grid was blanked' error appeared too early and prevented gridding
• Moving with arrows sometimes moved the object always left (or always right)
• The "Lock Position" feature still allowed a node to be moved when nudging with the arrow keys

Surfer 23.3.202 (March 30, 2022)

Improvements

• Common graphic files: add GML extension
• Update EULA in Surfer for subscription licensing

Fixes

• 3D View: default camera is far away when Map and layer have different coordinate systems
• 3D View: Export 3D: some surfaces export with the axis labels in the wrong location
• 3D View: Export to VRML: textured surfaces with blanked areas can lose surface color
• 3D View: Surfaces: shading resolution doesn't work anymore
• AutoSave: failure during recovery prevents Surfer from running
• Base (vector) layer: changing Map coordinate system reverses image
• Base Map: Ellipse, Rounded Rectangle, and Rectangle did not name properly using Attributes
• Base(vector): zipped SHP files imported without coordinate system information when there was a PRJ in ZIP
• Copy/Paste Format: undo/redo of actions can create multiple color scales and lead to crash
• Crash when Undo Paste Format
• Frame: Inaccurate bounding box when loading document with color scale in older versions
• Grid Data: text contents keep expanding after error until they're out of the dialog
• Internal Error after redoing unchecking of 'Show color scale' property (ColorScaleNode.cpp)
• Internal Error when certain limits & scale are applied (Axis.cpp)
• Internal Error when gridding some data using CoKriging (anisotropy.cpp)

Surfer 23.2.176 (February 1, 2022)

Improvements

• Map Wizard: remove Cokriging as a gridding method for simple gridding; and if gdMethod is set to Cokriging, change it to Kriging
• Defaults: Grid Data: add Cokriging option to gdMethod in UI and SET file description
• Common Document Files filter: Include .XLSX

Fixes

• 3D View: drillholes not displayed when the map had a geotransform
• 3D View: Export 3D PDF: exporting 3D surface layers lost the surface color
• Internal Error when importing some images as a base layer (rasterlayernode.cpp)
• Surfer splash screen showed 'Surfer Beta' instead of 'Surfer'
• Base from data: Labels: X offset for labels is very inaccurate when map did not have proportional XY scaling
• Grid from Contours: assigning NoData outside the convex hull produced different contours than when not assigning NoData
• Copy Format/Paste Format: does not copy/paste polyline End Styles
• Base(vector) layer: Labels: offset not correct when page units were cm

Surfer 23.1.162 (January 3, 2022)

New Features and improvements:

• 3D View: digitize point locations and save XYZ coordinates
• 3D View: improved accuracy of reported XYZ coordinates in the status bar
• Color Scale: add Frame with line and fill colors
• Color Scale: identify which layer it belongs to in Properties
• File Export: export a base layer with numeric attributes to a data format with numeric attributes
• Grid layers: Info page: display some grid information in the Properties window
• Map Wizard: create peaks and depressions layer
• Map Wizard: create point cloud layer
• Option to disable some warnings
• Save grid as grid-type GeoTIFF (TIF files with Zs instead of colors)
• Map Scale Bar: add Frame with line and fill colors
• Surface Map: show the base side-fill to a specified Z value
• Worksheet and Attribute Table: Save numeric values as numeric to DBF (do not convert them to text)

Fixes:

• 3D View: Point symbols did not export to 3D PDF or VRML correctly
• Base layer: Sub-selection bounding box was not updated correctly with undo/redo
• Crash after creating 3D view and getting error 'Unable to initialize the OpenGL context'
• Crash in 3D view after getting error about video driver
• Crash when printing
• Download Online Grids: WCS: Surfer was not downloading grid GeoTIFFs correctly
• Drawn polylines were sometimes shifted when opening a project saved in previous version
• Drillhole layer: deviation paths were displayed in 3D in the 2D plot window
• Grid Info: reported -nan(ind) for some statistics
• Internal Error in 3D view displaying drillholes (StatePresenter.cpp)
• Internal Error when moving a graticule layer from one map to another (GraticuleHelpers.cpp)
• Opening some Surfer 16 SRF files (e.g. MapTypes.srf) shut Surfer down
• Selection boxes did not update when adding shapes
