BreakingUpgrade verdict

7 breaking changes and a platform requirement change.

In plain terms
  • You can no longer put other components inside an Image. Use ImageBackground if you need content layered over an image.
  • Metro no longer reads .babelrc files inside node_modules by default, which avoids cryptic bugs from packages shipping their own Babel config.
  • On Android, Image no longer accepts child components.
  • ReactRawTextShadowNode no longer inherits from ReactTextShadowNode.
