> =================
> - [new] Add rule `anchor-is-valid`. See documentation for configuration options. Thanks [**AlmeroSteyn**](https://github.com/AlmeroSteyn).
> - [breaking] `href-no-hash` replaced with `anchor-is-valid` in the recommended and strict configs. Use the `invalidHref` aspect (active by default) in `anchor-is-valid` to continue to apply the behavior provided by `href-no-hash`.
> - [breaking] Removed support for ESLint peer dependency at version ^2.10.2.
> - [update] The rule `label-has-for` now allows inputs nested in label tags. Previously it was strict about requiring a `for` attribute. Thanks [**ignatiusreza**](https://github.com/ignatiusreza) and [**mjaltamirano**](https://github.com/mjaltamirano).
> - [update] New configuration for `interactive-supports-focus`. Recommended and strict configs for now contain a trimmed-down whitelist of roles that will be checked.
> - [fix] Incompatibility between node version 4 and 5. Thanks [**evilebottnawi**](https://github.com/evilebottnawi).
> - [fix] Missing README entry for `media-has-caption`. Thanks [**ismail-syed**](https://github.com/ismail-syed).
> - [fix] README updates explaining recommended and strict configs. Thanks [**Donaldini**](https://github.com/Donaldini).
> - [fix] Updated to aria-query@0.7.0, which includes new ARIA 1.1 properties. Previously, the `aria-props` rule incorrectly threw errors for these new properties.
> 
> 5.1.1 / 2017-07-03
