Release of ezdxf v1.4.0

[mozman]

Version 1.4.0 - 2025-03-08

• Release Notes v1.4.x

New Modules to Find Chains and Loops

• The ezdxf.edgeminer module for seaching of connected edges and closed loops to:
  • build polylines from DXF primitives like LINE, ARC, ELLIPSE, SPLINE
  • build hatch boundary paths from DXF primitives
  • find open chains or closed loops in an unordered heap of DXF primitives (edges)
  • in general: find connections between edges
• The ezdxf.edgesmith module for creating edges from DXF entities and creating polylines and hatches from connected edges:
  • create edges from DXF primitives for processing by the edgeminer module:
    • LINE, ARC, ELLIPSE, SPLINE, LWPOLYLINE, POLYLINE
  • create LWPOLYLINE and POLYLINE entities from a sequence of edges.
  • create HATCH boundary paths from a sequence of edges.
  • create ezdxf.path.Path objects from a sequence of edges.

• Documentation

The v1.4.x releases are the last with Python 3.9 support because Python 3.9 reaches End of Life in 2025-10.
