Just as an FYI in case someone runs into this styling problem after upgrading this plugin...
If you added custom styling to the widget via CSS, the author changed the CSS selectors with this new version. This means your custom widget styling will disappear when you upgrade the plugin.
To fix this you will need to go into your CSS file and make this change:
Old ID - #news-announcement
New ID - #news-announcement-scroll
Making that edit should bring your widget styling right back.
