v0.25.2 — Fix Blender 5.x Crash

🐛 Critical Fix

The addon no longer crashes Blender 5.0.1 on macOS Apple Silicon.

The previous release caused an instant EXC_BAD_ACCESS (SIGSEGV) during startup because the compiled native extension (sketchup.so) was built against incompatible Python headers. CPython 3.11 redesigned its internal code-object structs, and the old binary had wrong struct offsets baked in — causing _PyCode_Validate to read garbage memory on module load.

What Changed

• Recompiled with matching Python 3.11 ABI — extension now loads cleanly in Blender 5.0.1
• Upgraded Cython to 3.x — old Cython (0.29.x) generated C code with known CPython 3.11 incompatibilities
• Improved build script — build_release_macos.sh now auto-detects Blender's Python, verifies ABI compatibility, and falls back to Homebrew python@3.11 when Blender's Python lacks development headers
• Added build safety check — setup.py warns if you accidentally build with the wrong Python version

Compatibility

Blender	5.x (tested on 5.0.1)
macOS	Apple Silicon (arm64)
Python	3.11
SketchUp files	Up to 2025.1

SketchUp Importer v0.25.1 — macOS (Apple Silicon)

What's Fixed

• Fixed import crash on nested/duplicate components — Models with nested component definitions or auto-renamed duplicates (e.g. ComponentName#1) would crash with KeyError during import.
• Fixed duplicate processing — Removed accidental duplicate call to write_duplicateable_groups().

What's Improved

• macOS Apple Silicon (arm64) support
• Release build script (build_release_macos.sh)
• Modernized setup.py (distutils → setuptools)

Installation

1. Download the zip below
