Unreleased

Added

• Native AC1021 (R2007) read path in the high-level API (ezdwg.read) without compatibility conversion.
• Native AC1024 (R2010) read path in the high-level API (ezdwg.read) for LINE, ARC, and LWPOLYLINE.
• Native AC1027 (R2013) read path in the high-level API (ezdwg.read) for LINE, ARC, and LWPOLYLINE.
• AC1021 regression suite covering:
• Rust object/entity decode checks for LINE, ARC, LWPOLYLINE.
• Python high-level and raw API checks with paired sample files.
• CLI inspect verification for native decode_version: AC1021.
• AC1024 regression suite covering high-level and raw geometry checks against paired DXF samples for:
• LINE
• ARC
• LWPOLYLINE
• AC1027 regression suite covering high-level and raw geometry checks against paired DXF samples for:
• LINE
• ARC
• LWPOLYLINE
• R2007+/R2010+/R2013+ regression coverage for:
• POINT
• CIRCLE
• ELLIPSE
• TEXT/MTEXT regression coverage for R2000/R2004 sample pairs.

Changed

• Removed the external DWG compatibility-conversion path from ezdwg.read; AC10xx versions in scope now use native decode paths.
• R2007/R2010/R2013 entity decoding now uses version-aware common header paths for:
• LINE
• ARC
• LWPOLYLINE
• POINT
• CIRCLE
• ELLIPSE
• TEXT
• MTEXT
• DIMENSION (linear/radius/diameter) to account for material flags, shadow flags, R2010 visual-style bits, and the R2013+ ds-binary-data flag.

Notes

• This release keeps API signatures stable (ezdwg.read, ezdwg.raw, entity decode functions).
• ARC angles remain radians in ezdwg.raw and degrees in the high-level API.
• AC1021/AC1024/AC1027 style-handle and layer-color resolution for LINE/ARC/LWPOLYLINE is currently best-effort on some files.
