<commit_before>UPGRADE FROM 2.x to 3.0
=======================

### ClassLoader

 * The `UniversalClassLoader` class has been removed in favor of
   `ClassLoader`. The only difference is that some method names are different:

      * `registerNamespaces()` -> `addPrefixes()`
      * `registerPrefixes()` -> `addPrefixes()`
      * `registerNamespaces()` -> `addPrefix()`
      * `registerPrefixes()` -> `addPrefix()`
      * `getNamespaces()` -> `getPrefixes()`
      * `getNamespaceFallbacks()` -> `getFallbackDirs()`
      * `getPrefixFallbacks()` -> `getFallbackDirs()`

 * The `DebugUniversalClassLoader` class has been removed in favor of
   `DebugClassLoader`. The difference is that the constructor now takes a
   loader to wrap.

### Console

 * The methods `isQuiet`, `isVerbose`, `isVeryVerbose` and `isDebug` were added
   to `Symfony\Component\Console\Output\OutputInteface`.

### EventDispatcher

 * The interface `Symfony\Component\EventDispatcher\Debug\TraceableEventDispatcherInterface`
   extends `Symfony\Component\EventDispatcher\EventDispatcherInterface`.

### Form

 * The methods `Form::bind()` and `Form::isBound()` were removed. You should
   use `Form::submit()` and `Form::isSubmitted()` instead.
