Release 3.8.1

Changes:

1. We can now type React components with static members as `React.ComponentType` (instead of requiring the `StatelessFunctionalComponent`) hack.
2. We can now type-parameterize React components on all of their props, instead of just the ones we care about. Not sure why this wasn't previously. Note: this is a breaking change, in the sense that people's parameterization of `NavigationScreenComponent`, `NavigationNavigator`, and `NavigationContainer` may need to change.
3. The order of object-type-spread in the `getParam` definition has been switched. It was giving errors with the old order.
4. Avoid recursive type inference `NavigationScreenProp`. This was yielding an "*** Recursion limit exceeded ***" error, which was rather difficult to debug. We can just use a `NavigationState` and let the user cast.
5. Fix `onTransitionStart`/`onTransitionEnd` types in `NavigationStackViewConfig`.
6. Add `navigationConfig` property to `NavigationView`.

-## [2.9.0] - [2018-07-20](https://github.com/react-navigation/react-navigation/releases/tag/2.9.0)
-### Added
-- `headerLayoutPreset: 'center' | 'left'` to provide an easy solution for [questions like this](https://github.com/react-navigation/react-navigation/issues/4615).
-- `headerBackTitleEnabled` - this configuration option for stack navigator allows you to force back button titles to either be rendered or not (if you disagree with defaults for your platform and layout preset).
+## Fixes
 
-### Fixed
-- Android back button ripple is now appropriately sized (fixes [#3955](https://github.com/react-navigation/react-navigation/issues/3955)).
-- Respect header background color on container (fixes edge case where user depended on displaying content that was rendered behind the navigator, this particular behavior should not be depended on and may break in the future, but this change is still useful regardless).
+- `onRefresh` on exported lists `FlatList` and `SectionList` works as expected now (no need to add `refreshControl` prop explicitly)
+- On Android, the exported `ScrollView` is now same as the React Native ScrollView (but with scroll-to-top behavior added), whereas on iOS we still use react-native-gesture-handler ScrollView. We can change Android back to react-native-gesture-handler ScrollView when https://github.com/kmagiera/react-native-gesture-handler/issues/560 is resolved.
+- Look for `scrollResponderScrollTo` function in our ScrollView, in react-native 0.59 the interface appears to have changed for FlatList such that this is needed. (react-navigation-native#20)

-## [2.8.0] - [2018-07-19](https://github.com/react-navigation/react-navigation/releases/tag/2.8.0)
-### Added
-- `headerLeftContainerStyle`, `headerTitleContainerStyle`, and `headerRightContainerStyle` are exposed on `navigationOptions`. These properties allow you to customize the style of the container of `headerLeft`, `headerTitle` and `headerRight` components.
+## [3.0.5] - [2018-12-03](https://github.com/react-navigation/react-navigation/releases/tag/3.0.5)
 
-### Fixed
-- Fixed memory leaks in `createNavigator`: [closure scope leak](https://github.com/react-navigation/react-navigation/commit/1a765562905e93bbae0262dd20c2688221c999e8), and [clean up old descriptors](https://github.com/react-navigation/react-navigation/commit/93642e16e7ff029586b68ee732ec790504ee4862).
+## Fixes
 
-## [2.7.0] - [2018-07-17](https://github.com/react-navigation/react-navigation/releases/tag/2.7.0)
-### Added
-- The enableURLHandling prop on the top level navigator component allows you to disable deep linking handling. Currently it is always enabled. To disable it, `<RootNavigator enableURLHandling={false} />`
+- Fix crash in rare case where onNavigationStateChange on container leads to setState and container has screenProps (https://github.com/react-navigation/react-navigation/issues/5301)
+- Expose underlaying ScrollView methods to NavigationAwareScrollable (https://github.com/react-navigation/react-navigation-native/pull/8)
 
-### Changed
-- StackNavigator.replace method no longer requires a key param. If the key is left undefined, the last screen in the stack will be replaced.
+## [3.0.4] - [2018-11-30](https://github.com/react-navigation/react-navigation/releases/tag/3.0.4)
 
-### Fixed
-- Support headerLeft component for the first screen in a stack (#4608).
-- Removed bottomBorder when `headerTransparent` is set to true.
-- Improve empty path and param handling in deep linking (#4671). This fixes issues with deep linking and fully tests the differences between path: '' and path: null. Empty string matches empty paths, and null path will let the child router handle paths at the same level. Also it makes sure that params are not duplicated between path and query when they are serialized with getPathAndParamsForState.
-- Fix onTransitionStart not being invoked when provided in navigator config.(#4100)
-- Rare case when users navigated back and forth quickly with exactly the right timing would cause a crash due to a scene being queued to transition, then clobbered, then attempted to render as a stale scene but without a descriptor. ([commit](https://github.com/react-navigation/react-navigation/commit/cab4d71a5e09188df3f4a294c98779eecb860a78))

-## [2.6.1] - [2018-07-05](https://github.com/react-navigation/react-navigation/releases/tag/2.6.1)
-### Added

+## Fixes
 
-### Fixed
-- Fixed missing header shadow on Android.
+- Fix crash when screenInterpolator is null (https://github.com/react-navigation/react-navigation-stack/issues/64)
+- Fix renderPager override (https://github.com/react-navigation/react-navigation-tabs/pull/70)
 
-## [2.6.0] - [2018-07-04](https://github.com/react-navigation/react-navigation/releases/tag/2.6.0)
-### Added

+## Added
 
-### Fixed
-- Fix stack router child router delegation priority (https://github.com/react-navigation/react-navigation/commit/e8c1833053e37d28f0ce505ff323565abf23b6a2)
-- Avoid crash when calling isFocused on old route (https://github.com/react-navigation/react-navigation/commit/0921889f7a3acfc6d6bcc4909d209eeeee985ba7)
-- Stack router no longer attempts to parse query params within path handling
-- Switch router now has exact same param treatment for URLs as stack router does
+- Accessibility labels on drawer items (https://github.com/react-navigation/react-navigation-drawer/pull/30)
 
-### Changed
-- Internally we no longer need to special case PlatformHelpers by platform as react-native-web handles the APIs we mocked out with it now.
 
-## [2.5.5] - [2018-06-27](https://github.com/react-navigation/react-navigation/releases/tag/2.5.5)
-### Added
-- Throw error in development mode when header navigation option is set to a string - a common mistake that would otherwise result in a cryptic error message.
-- Throw error in development mode when title is not a string.
+## [3.0.3] - [2018-11-30](https://github.com/react-navigation/react-navigation/releases/tag/3.0.3)
 
-### Fixed
-- Delegate to child routers for more than just the top screen in the stack.
-- Update react-navigation-drawer to 0.4.3 to fix `initialRouteParams` option
+## Fixes
 
-## [2.5.4] - [2018-06-27](https://github.com/react-navigation/react-navigation/releases/tag/2.5.4)
-### Fixed
-- Header no longer sometimes flashes for 1 frame when using `header: null` on initial route of stack with floating header.
-- Export `createSwitchNavigator` in react-navigation.web.js
+- Fix bug where if you navigate immediately when the navigator is first mounted the stack could get in an invalid state.
+- Transparent stack card factors in header height now, even though you probably won't want to use this.
+- Fix bug where shadow was still rendered on transparent stack
+- Fix gestureResponseDistance custom values being ignored for modal stack
 
-## [2.5.3] - [2018-06-23](https://github.com/react-navigation/react-navigation/releases/tag/2.5.3)
-### Fixed
-- `setParams` applies to the navigation object it is called on even if that is the navigation object for a navigation view (more details in https://github.com/react-navigation/react-navigation/issues/4497)
+## [3.0.2] - [2018-11-27](https://github.com/react-navigation/react-navigation/releases/tag/3.0.2)

+## Fixes
 
-## [2.5.1] - [2018-06-22](https://github.com/react-navigation/react-navigation/releases/tag/2.5.1)
-### Fixed
-- `transitionConfig` in stack navigator no longer passes incorrect `fromTransitionProps` when navigating back
+- Fix `drawerLockMode` on drawer navigator
+- Fix RTL support in drawer navigator
 
-## [2.5.0] - [2018-06-22](https://github.com/react-navigation/react-navigation/releases/tag/2.5.0)
-### Changed
-- Refactor internals to make it play more nicely with web

 React Navigation is born from the React Native community's need for an extensible yet easy-to-use navigation solution based on Javascript.
 
 ## Installation
 
-Since the library is a JS-based solution, to install the latest version of react-navigation you only need to run:
-
-```bash
-yarn add react-navigation
-```
-
-or
-
-```bash
-npm install --save react-navigation
-```
+See: https://reactnavigation.org/docs/en/getting-started.html
 
 ## Documentation

 #### Is this the only library available for navigation?
 
-Certainly not! There other libraries - which, depending on your needs, can be better or worse suited for your project. Read more in the [alternative libraries](https://reactnavigation.org/docs/alternatives.html) documentation, and read React Navigation's [pitch & anti-pitch](https://reactnavigation.org/docs/pitch.html) to understand the tradeoffs.
