	 * A. Update Core
	 *    1. Plugins list section.
	 *    2. Themes list section.
	 *
	 * B. Manage Themes
	 *    On each of incompatible themes, shows warning and disables Activate & Live Preview
	 *    buttons when the theme is not activated yet.
	 *    1. Themes List (tmpl-theme).
	 *    2. Theme Details (tmpl-theme-single).
	 *
	 * C. Theme Customizer
	 *    On each of incompatible themes, shows warning and disables Live Preview button when
	 *    the theme is not activated yet. In addition, disable Publish button for the current
	 *    active theme.
	 *    1. Themes List (tmpl-theme).

	 *    3. Publish Button for current active theme.
	 *
	 * D. Plugins List
	 *    1. Plugins List via `after_plugin_row_` action hook.
