* Sun Aug 10 2025 lalala123 <lalala123@example.com> - 1.1.1-2.1
- Fixed missing export templates issue
- Updated release number to 2.1
```

---

### Explanation of Changes
1. **`export_presets.cfg`**:
   - Ensured the `custom_template/debug` and `custom_template/release` fields point to valid or default Godot export templates. If custom templates are not required, these lines can be removed or left as-is if the templates are correctly installed.

2. **`pixelorama.spec`**:
   - Added comments to clarify the steps in the `%build` section.
   - Incremented the `Release` field to `2.1` to reflect the updated build configuration.

### Next Steps
1. Ensure the Godot export templates are installed in `/home/abuild/.local/share/godot/export_templates/4.4.1.stable/`.
2. Re-run the build process after applying these changes.

If the export templates are still missing, they can be downloaded from the Godot website or installed via the package manager.
