React Native: v0.42.3 Release

This is February 2017 release, also known as 0.42.0.

Breaking changes

Xcode 8.x is required

Older compilers for iOS such as Xcode 7.x's are no longer supported. Please upgrade to the latest version of Xcode.

Android: windowSoftInputMode for new apps

e3d4ace - @mkonicek

All new apps created with react-native init are going to have windowSoftInputMode:adjustResize instead of adjustUnspecified, which is default. That change makes keyboard handling on Android automatic and doesn't require any Javascript solutions, like KeyboardAvoidingView to be used. You can see the rationale behind that change along the screenshots here. It shouldn't be breaking for most of the users.

Android: (Re)move JSBundleLoader.getSourceUrl()

89d72c9 - @amnn

If you are using any of the following API's to access the Source URL of the bundle: - JSBundleLoader.getSourceUrl() - ReactInstanceManager.getSourceUrl() - ReactInstanceManager.getJSBundleFile()

you have to now refer to the source of truth for this information, which is at CatalystInstance.getSourceURL(), or the return value of JSBundleLoader.loadScript().

Android: Remove RecyclerViewBackedScrollView

6ec5654 - @mkonicek

RecyclerViewBackedScrollView was added a long time ago to work around the scroll-back-when-data-is-added bug, but that has now been fixed directly in the ScrollView (ReactScrollView.java) in open source and internally.

Both: Improve validation of transform property

0ed31eb - @janicduplessis

This commit improves validations of the transform object that are done on the Javascript side and makes it a bit stricter (hence the breaking change). When moving transform objects parsing to native the validations got out of sync a bit. In this change we make sure JS validations are the same or stricter than the native ones to make sure we get consistent errors across platforms.
