Key highlights include new `phx.*` code generators replacing the old `phoenix.*` tasks, a new Contexts pattern that enforces API boundaries between your web interface and domain logic, first-class umbrella project support, and the `action_fallback` controller feature for cleaner error handling. The project structure moves `web` inside `lib`, reinforcing Phoenix as a web interface layer rather than the entire application. The release is backwards compatible — upgrading is as simple as bumping the dependency version, with an upgrade guide available for adopting new conventions. ## Full article daily.dev links to this article rather than hosting it.
