Deprecates all use of constants. * HEADER_TEXTCOLOR is now (string) 'default-text-color'. * NO_HEADER_TEXT is nowi ! (bool) 'header-text'. * HEADER_IMAGE_WIDTH (and _HEIGHT) are now (int) 'width' and 'height'. * HEADER_IMAGE is now (string) 'default-image'. * The 3.4 arguments 'suggested-width' and 'suggested-height' are now just 'width' and 'height' (they are "suggested" when flex-width and flex-height are set). * Callback arguments for add_custom_image_header() can now be passed to add_theme_support(). Custom background: Use add_theme_support('custom-background, $args) instead of add_custom_background(). Deprecates all use of constants. * BACKGROUND_COLOR is now (string) 'default-color'. * BACKGROUND_IMAGE is now (string) 'default-image'. * Callback arguments for add_custom_background() can now be passed to add_theme_support(). Inheritance: add_theme_support() arguments for custom headers and custom backgrounds is a first-one-wins situation. This is not an unusual paradigm for theming as a child theme (which is included first) overrides a parent theme. * Once an argument is explicitly set, it cannot be overridden. You must hook in earlier and set it first. * Any argument that is not explicitly set before WP is loaded will inherit the default value for that argument. * It is therefore possible for a child theme to pass minimal arguments as long as the parent theme specifies others that may be necessary. * Allows for a child theme to alter callbacks for <head> and preview (previously, calling add_custom_image_header more than once broke things). * The just-in-time bits ensure that arguments fall back to default values, that the values of all constants are considered (such as one defined after an old add_custom_image_header call), and that all constants are defined (so as to be backwards compatible). get_theme_support(): Introduce new second argument, which headers and backgrounds leverage to return an argument. current_theme_supports() already supported checking the truthiness of the argument. * For example, get_theme_support( 'custom-header', 'width' ) will return the width specified during registration. * If you had wanted the default image, use get_theme_support( 'custom-header', 'default-image' ) instead of HEADER_IMAGE.
