New description:

 Deprecated functions are used in the functions.php file of Twenty Eleven
 theme.
 1) `add_custom_background()`
 2) `add_custom_image_header()`

 We need to use the `add_theme_support()` function instead of that.

Comment:

 Hi and thanks for the report!

 This is not a bug because the theme uses `add_theme_support()` for both
 `custom-header` and `custom-background` in `twentyeleven_setup()`. The
 deprecated functions were added in changeset:20983 to support WordPress
 versions before 3.4. Anyone who might still have a very old, unsupported
 version of WordPress likely will not update the theme either, but I think
 this is fine to keep in functions.php.
