-#### Opening Pull Requests for Breaking Changes
-
-Pull requests that include Breaking Changes must be opened against the `next` branch instead of `release-x.x`.
-This ensures that breaking changes are accumulated and released together in the next major version, minimizing disruption for consumers.

 Paragon is distributed on npm as ES6 modules.  This means that webpack can use treeshaking on any Paragon components that a consuming app is not using, resulting in greatly reduced bundle sizes.
