THIS IS A RELEASE CANDIDATE: this means it's not stable yet.
Please refrain from upgrading from now, unless you want to collaborate in testing it to make sure that 0.59.0 will be fully stable - which would be super useful
To test it, run
react-native init RN059 --version react-native@next
Some of the major changes that this version will bring:
- React Hooks
- the CLI is extracted to this repository
- quite a few new deprecated Components
- a whole lot of QoL improvements on the native Android side (64 bits support via a new JSC, AppCompatActivity, etc) - some of which will be Breaking Changes (for brownfield apps)
(once we reach stable we will create the full changelog, these are only a few highlights)
You can refer to this issue for updates on the RC status, and you can post there your bug reports.
If you feel particularly brave: you'll find a new
metro.config.js in your App template: https://github.com/facebook/react-native/blob/0.59-stable/template/metro.config.js#L12-L13
turn the two flags to
true which may bring significant perf improvements. Here is a basic explanation of inline requires/imports.
