Currently, all build branches created with the Native Builder come off the master branch. Where I foresee issues coming in the near future is we’ll have a production app on React Native 0.59. We’ll need to provide support to this version for some time. At the same time, our next version of the app is being built on React Native 0.61. If we had a support branch for 0.59 that new support builds could be branched off from, and a branch for 0.61 that we could switch to on the fly, that would make our build process much easier.
