css - What CSS3 features still need vendor prefixes?

Question

The most common features I remember needing prefixes for were features such as flexbox, border-radius, box-shadow, etc... but now they are supported. With more users switching to more powerful browsers like Chrome and Firefox and away from IE, are there still features now that haven't been fully supported and require prefixes?

Use the site http://shouldiprefix.com. It has the single purpose to "show what prefixes are needed for a newer CSS property."

Just enter the property you're interested in the search field, and it will return something like the below graphic:
