		## [HEAD]

		- Feature: Added `history.getCurrentLocation()` method
		- Breakage: `history.listen` no longer calls the callback synchronously once.
		Use `history.getCurrentLocation` instead
		- Breakage: `location.key` on the initial POP is `null`. Users who relied on
		this key may immediately use `replace` to get it back
		- Breakage: `location.state` is `undefined` (instead of `null`) if the location
		has no state. This helps us know when we need to access session storage and when
		we can safely ignore it
		- Bugfix: Hash history now uses a custom query string key/value pair only if
		the location has state. This obsoletes using `{ queryKey: false }` to prevent
		the query string from being used ([#163])
		- Bugfix: Do not access `window.sessionStorage` unless the location has state.
		This should minimize the # of times we access session storage and allow users to
		opt-out of using it entirely by not using location state
