 - Ability to view remote timelines, with ex. `/api/v1/timelines/public?instance=lain.com` and streams `public:remote` and `public:remote:media`.
 - The site title is now injected as a `title` tag like preloads or metadata.
 - Password reset tokens now are not accepted after a certain age.
+- OAuth form improvements: users are remembered by their cookie, the CSS is overridable by the admin, and the style has been improved.

     Note the extra `static` folder for the terms-of-service.html
 
 Terms of Service will be shown to all users on the registration page. It's the best place where to write down the rules for your instance. You can modify the rules by adding and changing `$static_dir/static/terms-of-service.html`.

+## Styling rendered pages
+
+To overwrite the CSS stylesheet of the OAuth form and other static pages, you can upload your own CSS file to `instance/static/static.css`. This will completely replace the CSS used by those pages, so it might be a good idea to copy the one from `priv/static/instance/static.css` and make your changes.
