Changelog

---

Welcome to the January 2019 release of React Native. There are a number of significant changes in this version, and we'd like to especially call your attention to:

• Modernizing and stengthening flow types for core components
• Break changes to ScrollView, CameraRollView, and SwipeableRow that make it no longer bound to the component instance in certain methods
• Support for mutual TLS in WebKit
• Asset serving from directories besides /assets
• Numerous crash fixes and resolutions for unexpected behavior

Thanks to those who gave feedback on our release candidates. If you're interested in helping evaluate our next release, check you our tracking issue here.

Added

• Add support for publicPath to enable serving static assets from different locations (0b31496 by @gdborton)

Android specific

• Bundler server host can now be set using Android System Properties, making for easier debugging across multiple apps or app installs adb shell setprop metro.host (e02a154 by @stepanhruda)
• Native Modules can now reject a promise with an additional WritableMap arg for extra properties (userInfo). See the interface defined in Promise.java for available methods. This is accessible in JavaScript as Error.userInfo. This is to match iOS's existing Error.userInfo behaviour. See PR for examples. (#20940 by @Salakar)
• Native Modules now expose a nativeStackAndroid property to promises rejected with an Exception/Throwable - making native error stacks available inside Javascript: Error.nativeStackAndroid. This is to match iOS's existing Error.nativeStackIOS support. See PR for examples. (#20940 by @Salakar)

iOS specific

• Add moduleForName: lazilyLoadIfNecessary to RCTBridge.h to lookup modules by name and force load them, plus various improvements to LazyLoading (d7a0c44, 6534718, d7865eb, 04ea976, 1f394fa, 80f92ad, and 81b74ec by @dshahidehpour, @fkgozali, and @mmmulani)
• Add ability for WebView to setClientAuthenticationCredential when useWebKit={true} for mutual TLS authentication (8911353 by @mjhu)

Changed

• Major improvements to Flow types for Core Components (499c195, fbc5a4f, f9050e0, 6476151, c03fc40, 69213ee, 136dfc8, 3c0211b, c127000, 636e146, 6fa997d, 35a65cd, 7927497, 45c5183, a97d104, fb4825a, 84c5416, 3649a50 by @mottox2, @saitoxu, @RSNara, @watanabeyu, @Tnarita0000, @exced, @nd-02110114, @flowkraD)
• Many public components were converted to ES6 classes (ScrollView by @thymikee, CameraRollView, SwipeableRow and ProgressBarAndroid by @exceed, ProgressViewIOS by @empyrical, SegmentedControlIOS, ToolbarAndroid by @nd-02110114
• Flow dependency is now at v0.86.0 (8fb228f by @panagosg7)
• metro dependency is now at v0.49.1 (f867db3, 8888295, 31bb551, de60e86, and a525941 by @alexkirsz and @rafeca)
• jest dependency is now at v24.0.0-alpha.6 (1b4fd64, 66aba09, and 06c13b3 by @rafeca and @rubennorte)
• fbjs-scripts dependency is now at v1.0.0 (#21880) (cdbf719 by @jmheik)
• folly dependency is now at v2018.10.22.00 (a316dc6, 19a7ecc, and a70625a by @Kudo and @radko93)
• React sync for revisions 4773fdf...6bf5e85 (0cb59b5 and e54d1e2 by @yungsters)
• Clearer error messages when hot reloading (c787866 by @alexkirsz)
• Allow CxxModules to implement functions which take two callbacks (8826d8b by @acoates-ms)

Breaking Changes

• Public methods of components converted to ES6 classes are no longer bound to their component instance. For ScrollView, the affected methods are setNativeProps, getScrollResponder, getScrollableNode, getInnerViewNode, scrollTo, scrollToEnd, scrollWithoutAnimationTo, and flashScrollIndicators. For CameraRollView, the affected methods are: rendererChanged. For SwipeableRow, the affected methods are: close. Therefore, it is no longer safe to pass these method by reference as callbacks to functions. Auto-binding methods to component instances was a behaviour of createReactClass that we decided to not preserve when switching over to ES6 classes.

Android specific
