* BREAKING CHANGE: the API for the `function` module has changed. The `interpolated` and `piecewise-constant` exports
were replaced with a single unnamed export, a function which accepts an object conforming to the style spec "function"
definition, and an object defining a style spec property. It handles color parsing and validation of feature values
internally.
* Functions now support a "default" property.
* `parseColor` was promoted from gl-js.

## 8.0.0

Introduction of Mapbox GL style specification v8. To migrate a v7 style to v8,
use the `gl-style-migrate` script as described in the README.

* [BREAKING] The value of the `text-font` property is now an array of
  strings, rather than a single comma separated string.
* [BREAKING] Renamed `symbol-min-distance` to `symbol-spacing`.

  now use `mapbox://fonts/mapbox/{fontstack}/{range}.pbf`.

  layers.
