### Added
- `helmet.contentSecurityPolicy`:

- `helmet.hidePoweredBy` no longer accepts arguments. See [this article](https://github.com/helmetjs/helmet/wiki/How-to-set-a-custom-X%E2%80%93Powered%E2%80%93By-header) to see how to replicate the removed behavior. See [#224](https://github.com/helmetjs/helmet/issues/224).

Read ["How to disable blocking with X-XSS-Protection"](https://github.com/helmetjs/helmet/wiki/How-to-disable-blocking-with-X%E2%80%93XSS%E2%80%93Protection) and ["How to enable the `report` directive with X-XSS-Protection"](https://github.com/helmetjs/helmet/wiki/How-to-enable-the-%60report%60-directive-with-X%E2%80%93XSS%E2%80%93Protection) if you need the legacy behavior.
