React 15.2.0 warning: Unknown prop literal on <p> tag

[tajo]

React 15.2.0 throws a warning if you try to assign custom props to DOM elements. Custom props should be assigned only to React components.

warning.js?8a56:44Warning: Unknown prop `literal` on <p> tag. Remove this prop from the element. For details, see https://fb.me/react-unknown-prop
    in p (created by ReactMarkdown)
    in div (created by ReactMarkdown)
    in ReactMarkdown (created by MY_APP_COMPONENT)

This warning appears with any source input.
I just had to fix the same thing in my library.

In meantime, I can recommend this alternative https://github.com/vincent-p/react-marked-markdown - it's just a wrapper for https://github.com/chjj/marked - works great.

I also get

debugger.js:11382 Warning: Unknown props `level`, `literal`, `nodeKey` on <h2> tag. Remove these props from the element. For details, see https://fb.me/react-unknown-prop
    in h2 (created by Heading)

    in div (created by ReactMarkdown)

Solved in 2.4.0.
