Resource hints allow browsers to prefetch specific pages or render them in the background to perform DNS lookups or to begin the connection handshake (DNS, TCP, TLS) in the background.
By default, `wp_resource_hints()` prints hints for "s.w.org" (the WordPress.org CDN) and for all scripts and styles which are enqueued from external hosts.
Use the `wp_resource_hints` filter to add custom domains and URLs for `dns-prefetch`, `preconnect`, `prefetch` or `prerender`.

In the past, `get_blog_details()` has been used to retrieve the `home`, `siteurl`, `blogname`, and `post_count` options for a site. By lazy loading properties in a `WP_Site` object, we can avoid having to use `get_blog_details()` and instead provide the properties as needed.
This introduces the global `site-details` cache group in which standard objects representing the site are stored. This will one day be a replacement for the `blog-details` cache group that is currently used in `get_blog_details()`.
This relies on the `ms_loaded` action introduced in [37916] as properties are not available via `get_option()` until multisite has been fully loaded.

This adds three new functions for getting/displaying attachment captions:
* `wp_get_attachment_caption` - Retrieves a caption for a specific attachment.
* `get_the_post_thumbnail_caption()` - Returns the post thumbnail caption.
* `the_post_thumbnail_caption()` - Displays the post thumbnail caption.
These are helpful for displaying a caption associated with an image directly
in a template, rather than using the caption shortcode.
This also introduces two new filters:
* `wp_get_attachment_caption` - Filters the value of `wp_get_attachment_caption()`.
* `the_post_thumbnail_caption` - Filters the display of the post thumbnail caption.
`the_post_thumbnail_caption()` is automatically filtered by `wptexturize()`,
`convert_smilies()`, and `convert_chars()` in `wp-includes/default-filters.php`.

The new format looks like "Sorry, you are not allowed to <action>.". This provides a consistent experience for all error messages related to missing permissions. It also reduces the number of similar strings and allows translators to provide a consistent style in their language.

Provides a consistent way to query `$wpdb->site` for `WP_Network` objects based on domain, path, network ID, and (main) site ID.
Introduces and uses update_network_cache() and _prime_network_caches() to maintain a cached list of WP_Network objects for use in multiple queries.

Given a network ID or network object, `get_network()` retrieves network data in the same vein as `get_site()` or `get_post()`. This will allow for clean retrieval of networks from a primed cache when `WP_Network_Query` is implemented.

This changes the global `$wp_post_types` to an array of `WP_Post_Type` objects. `WP_Post_Type` includes methods to handle post type supports, rewrite rules, meta boxes, hooks, and taxonomies.
Each post type argument becomes a property of `WP_Post_Type`.

In [37657], the `blog_id` and `site_id` properties were changed to private. Any `WP_Site` objects previously stored in cache with public properties should now be considered invalid. We can detect this by checking for these missing properties and clearing the dirty cache if found.
