* Why is Offline Mode Important?

  Offline mode is essential for breaking the requirement that m2 operate in a
  network-connected environment. It means legitimizing a development environment
  in which there is no network connection, and providing a robust m2 service
  offering in such circumstances. Introduction of offline mode allows m2 to

 *  **Call canceling is more reliable.**  We had a bug where a socket being
     connected wasn't being closed when the application used `Call.cancel()`.

 *  **Changing a HttpUrl’s scheme now tracks the default port.** We had a bug
    where changing a URL from `http` to `https` would leave it on port 80.
