single-{post_type}-{post_name}.php: New theme template in WordPress 4.4

A new theme template has been added to the theme hierarchy as of r34800: single-{post_type}-{post_name}.php.  This template follows the rules of is_single() and is used for a single post or custom post type. It’s most useful for targeting a specific post in a custom post type, and brings consistency to the templates available for pages and taxonomies. It comes in the hierarchy before single.php and single-{post_type}.php.

Don’t forget, too, that in WordPress 4.3 singular.php was introduced and the hierarchy of attachment templates was fixed.
