+### Release Process and React Native
+
+#### We want to release to React Native more frequently
+
+* Can we push more frequently like we do with the Facebook website?
+* What if we ship React minor releases (or patch releases) every two weeks?
+* We should be using a public stable release of React (either a minor or patch) on the website.
+* This would coincide with the React Native release process.
+
+#### React Native users have way more third-party dependencies
+
+* These won’t be compatible with “pre-release” or bleeding edge versions of React.
+* The only people that use RC are folks that have something that was fixed (usually by them) in the RC.
+* Otherwise, upgrading so frequently is incredibly draining.
+
+#### Should we have feature flags, like Ember does?
+
+* Maybe this would help catch regressions earlier.
+* On the other hand, this causes an explosion of possible build configurations.
+
+#### If we’re releasing more frequently we need to be testing React Native more
+
+* We need to be testing the React release in React Native.
+* Everyone on the team needs to have a working React Native setup on their machines.
+
+#### Should we publish nightly releases?
+
+* Can React Native lock itself into whatever nightly it wants?
+* But we don’t want React Native to be pegged to a specific commit.
+* This is pretty much what we started doing in 15.x with `alpha` releases for patches.
+
+#### Current plan
+
+* Going to publish `alpha`s, which can be released as frequently as we want, even like 4 a day.
+* Once something is stable and we’re confident it's working in React Native, we’ll cut an actual release.
+* React Native and Relay always reference a stable release in their dependencies.
+
+#### What will our messaging be about alphas?
+
+* Alpha = use at your own risk.
+* If you depend on an alpha due to an urgent fix you need, pin it to a specific version.
+* Guidance should be “never publish anything to npm with an alpha dependency”.
+
+#### Open question: where does the breaking change development happen?
+
+* Are we on `15.1.0-dev` or `16.0.0-dev`?
+* Do we merge breaking changes to master?
+* Currently we cherry-pick commits to `15-stable` but this is frustrating because 99% changes are not breaking.
+* Need to discuss more, no conclusion yet.
+
+### Experimenting with `StyleSheet.create()` on the web
+
+* [Christopher](http://twitter.com/vjeux) continues experimenting with `StyleSheet.create()` on the Facebook website codebase.
+* He made a proof of concept compiling these calls into CSS sheets compatible with Facebook internal asset pipeline.
+* Maintaining correct specifity with `StyleSheet.create()` is not an easy problem, but it may be solved by throwing errors early during development when there is a potential specificity issue, and providing a clear way for the developer to work around it.
+* Compiling `StyleSheet.create()` to emitting real CSS files through our internal asset pipeline lets us move a bit closer to experimenting with real inline styles without having to bet on them right now.
+* Nothing is certain, and Christopher will continue experimenting this month.
+* If it doesn’t turn out to be valuable, this will not make it into React! Don’t get too excited.
