Upgrading From 2.7 To 2.8
=========================

 * The route generation feature is deprecated, disable it explicitly:

   ```yaml
   fos_rest:
       routing_loader: false
   ```

   You need to configure your routes explicitly or consider using the
   [RestRoutingBundle](https://github.com/handcraftedinthealps/RestRoutingBundle).

 * Support for serializing exceptions has been deprecated. Disable it by setting the
   `fos_rest.exception.serialize_exceptions` option to `false` and use the ErrorRenderer component
   instead.

   You can use the `flatten_exception_format` option to serialize exceptions according to the API
   Problem spec (RFC 7807):

   ```yaml
   fos_rest:
       exception:
           flatten_exception_format: 'rfc7807'
   ```

 * Deprecated returning anything other than `string` or `null` from `resolve()` when implementing
   the `VersionResolverInterface`.

 * Passing version numbers as integers to `Context::setVersion()` is deprecated. Strings will be
   enforced as of 3.0.

 * The `isFormatTemplating()`, `renderTemplate()`, and `prepareTemplateParameters()` methods of the
   `ViewHandler` class and the `ViewHandlerInterface` have been deprecated.

 * The constructor of the `ViewHandler` class has been deprecated. Use the static `create()` factory
   method instead.

 * The `setTemplateVar()`, `setPopulateDefaultVars()`, `getTemplateVar()`, and `isPopulateDefaultVars()`
   methods of the `Controller\Annotations\View` class have been deprecated.

 * The `setEngine()`, `setTemplate()`, `setTemplateData()`, `setTemplateVar()`, `getEngine()`,
   `getTemplate()`, `getTemplateData()`, and `getTemplateVar()` methods of the `View\View` class
   have been deprecated.
