Surfer 30.2

What's new in this version:

Surfer 30.2
New Features and Improvements:
- Base from Server: add or fix background map to the preview window in the 'Download Online Maps' dialog
- Coordinate systems: Germany DHDN 3-degree Gauss was outdated

Fixed:
- Crash when importing LiDAR LAS/LAZ files with too many duplicate points; a new option to keep the youngest or oldest points was added
- Crash when pasting data in worksheet
- Grid Data: Insufficient data error sometimes occurred when gridding drillhole data
- Internal Error when creating 3D View with old 1-Grid Vector layer (Grid.cpp)
- Legends including base layers with unique values symbology: opening files saved in an older version could open without any properties shown in the legend or with incorrect bounds


Surfer 30.1
New Features and Improvements:
3D View:
- Contents: rename layers
- Drillholes: Create, Edit and Export contact picks
- Add multiple light sources; point or directional
- Prevent performance and memory problems when map frame is far larger than source grid
- Base Symbology: Unique Values: add Name field (for Legend)
