The theme configuration file’s `minimum_discourse_version` does not support date-based version formats. My version is 2025.12.0-latest, and I set the minimum version in the theme to 2025.12.0-latest. As a result, the console reported an error:

```bash
✘ Error 422 for http://localhost:4200/admin/themes/import.json: Invalid value in about.json: Minimum discourse version invalid

```

Should this be fixed?
