Older Blender Versions

Super IO 2.x requires Blender 5.0 or newer.

If you use Blender 4.x, 3.x, or 2.8x, install an older Super IO release from the GitHub Releases page.

Why The Split Exists

Blender 5 uses the new extension format and has different import/export operator APIs. Super IO 2.x drops old compatibility branches so the current code can focus on Blender 5 behavior.

Upgrade Checklist

Before upgrading from an older Super IO version:

1. Export your custom import/export config if possible.
2. Install the Blender 5 extension package from GitHub Releases.
3. Start Blender and let Super IO migrate old custom data when possible.
4. Check your custom operators, especially ones that target old Blender import/export operators.
