 We will always endeavor to support the latest stable version of TypeScript.
 
-The version of TypeScript currently supported by this parser is `~2.3.2`. This is reflected in the `devDependency` requirement within the package.json file, and it is what the tests will be run against. We have an open `peerDependency` requirement in order to allow for experimentation on newer/beta versions of TypeScript.
