+ * Add `Command::getCode()` to get the code set via `setCode()`.
  * Allow setting aliases and the hidden flag via the command name passed to the constructor
  * Introduce `Symfony\Component\Console\Application::addCommand()` to simplify using invokable commands when the component is used standalone
  * Deprecate `Symfony\Component\Console\Application::add()` in favor of `Symfony\Component\Console\Application::addCommand()`
