# Upgrading to 1.1.0

Version 1.1.0 adds portable logo, background, site-home, and board-icon settings. It continues to inherit standard CSS and JavaScript from SMF 2.1.7. If this version is copied over an existing DirtTwister installation, old duplicated files must not be left behind.

The cleanest manual upgrade is:

1. Preserve any local changes you intentionally made inside `Themes/DirtTwister`.
2. Replace the existing `Themes/DirtTwister` directory with the 1.0.5 directory.
3. Ensure `Themes/DirtTwister/css` and `Themes/DirtTwister/scripts` are writable by the PHP/web-server account.
4. Clear SMF's minimized CSS/JavaScript cache and hard-refresh the browser.
5. Open DirtTwister's Theme Settings to choose any custom image URLs, site-home values, or board-icon style. Blank values use the bundled defaults.

After replacement, `css/` should contain only:

- `dirttwister.css`
- `jquery.sceditor.theme.css`

The `scripts/` directory should contain only `index.php` until SMF generates new minimized files. Generated `minified_*` files may appear later and are normal, but they should not be distributed in the theme archive.
