January 2017

This is 0.41.0 release, referred to as "January 2017" according to the new release schedule.

New features

Android: Nodes

This feature is currently experimental. You can turn it on by applying this in your ReactNativeHost subclass.

Nodes is an experimental, alternate version of UIImplementation for ReactNative on Android. It has two main advantages over the existing UIImplementation:

• Support for overflow:visible on Android.
• More efficient generation of view hierarchies.

The intention is to ultimately replace the existing UIImplementation on Android with Nodes (after all the issues are ironed out).

Feature development and bug-fixes related to Nodes are listed below in a separate section for better clarity.

Check the readme for more details.
