Fires functions attached to a deprecated filter hook.When a filter hook is deprecated, the apply_filters() call is replaced with apply_filters_deprecated(), which triggers a deprecation notice and then fires the original filter hook. Note: the value and extra arguments passed to the original apply_filters() call must be passed here to `$args` as an array. For example: // Old filter. return apply_filters( 'wpdocs_filter', $value, $extra_arg ); // Deprecated. return apply_filters_deprecated( 'wpdocs_filter', array( $value, $extra_arg ), '4.9.0', 'wpdocs_new_filter' );
