> ## 6.0
> 
> * Fix `intersects` logic.

> 
> * Add `minVersion` method
> 
> ## 5.6
> 
> * Move boolean `loose` param to an options object, with
>   backwards-compatibility protection.
> * Add ability to opt out of special prerelease version handling with
>   the `includePrerelease` option flag.
> 
> ## 5.5
> 
> * Add version coercion capabilities
> 
> ## 5.4
> 
> * Add intersection checking
> 
> ## 5.3
> 
> * Add `minSatisfying` method
> 
> ## 5.2
> 
> * Add `prerelease(v)` that returns prerelease components
> 
> ## 5.1
> 
> * Add Backus-Naur for ranges
> * Remove excessively cute inspection methods
> 
> ## 5.0
> 
> * Remove AMD/Browserified build artifacts
> * Fix ltr and gtr when using the `*` range
> * Fix for range `*` with a prerelease identifier
