新しいページネーション関数　WordPress4.1

the_posts_pagination();

hook

$template= apply_filters( 'navigation_markup_template', $template, $class );

Note: Make WordPress Core

If you’ve written a child theme for Twenty Fifteen, please note that some of the new pagination functions have been renamed for a bit of clarity:

• the_pagination() is now the_posts_pagination()
• get_the_pagination() is now get_the_posts_pagination()
• These two functions now emit a “posts-navigation” HTML class, instead of “paging-navigation”
