+ 3.0.0 / 2016-10-11
+==================
+- [breaking] - Update all rule schemas to accept objects. This allows a future schema expansion to not be a breaking change.
+- [breaking] - All rules with schemas that accepted a string OR array, now only allows an array.
+- [new] - `href-no-hash` accepts new schema property `specialLink` to check for custom `href` properties on elements. (fixes [#76](https://github.com/evcohen/eslint-plugin-jsx-a11y/issues/76))
+
+Note - see [rule documentation](https://github.com/evcohen/eslint-plugin-jsx-a11y/tree/master/docs/rules) for updated schemas.
