To fix AttributeError and ImportError during Blender Python addon upgrades, map the tracebacks to version-specific API migrations, replacing removed or renamed functions using targeted replacement logic and version detection via bpy.app.version.

Migrating bgl to gpu in Blender Python scripts involves mapping deprecated bgl module calls to the modern gpu module and shader replacements, guided by a decision tree that ensures version-safe accessors across mixed Blender environments.

The bpy.ops context override fails because newer Blender versions changed the required context override handling, necessitating version-safe replacement accessors and updated operator calls to correctly execute Python operators without runtime errors.

Handling node interface changes and material property errors in Blender 4.x requires mapping TypeError and runtime enum issues to their specific API rewrites, updating node tree and property access using hasattr and version-conditional logic.

Yes, you can use bpy.app.version to write version-safe Blender Python code by applying conditional logic and hasattr checks, allowing your addons to dynamically select correct API paths across 3.x, 4.x, and 5.x environments.

TypeError and runtime enum issues in Blender shader code after a version update are caused by shader name changes and removed legacy properties, requiring migration to updated enum mappings and replacement GPU accessors.
