 ## Unreleased
 
+### 🎯 New Features
+- **Configurable minification**: New `TAILWIND_CLI_AUTOMATIC_MINIFY` setting and `--minify` / `--no-minify` flag on `tailwind build` for projects whose asset pipelines already minify CSS. Defaults preserve existing behavior.
+
 ### 🛠️ Developer Experience
 - **Gitignore cleanup**: Trimmed `.gitignore` to project-relevant entries only

+### TAILWIND_CLI_AUTOMATIC_MINIFY
+
+**Default**: `True`
+
+Controls whether `python manage.py tailwind build` passes `--minify` to the Tailwind CLI. Set to `False` if your asset pipeline already minifies CSS (for example when using `django-compressor` or a CDN transform) so you don't minify twice.
+
+This setting only changes the default; the `build` command also accepts an explicit `--minify` / `--no-minify` flag which takes precedence.
