In addition to `wp_list_filter()` for filtering a list of objects, and `wp_list_pluck()` for plucking a certain field out of each object in a list, this new function can be used for sorting a list of objects by specific fields. These functions are now all contained within the new `WP_List_Util()` class and `wp_list_sort()` is used in various parts of core for sorting lists.

One thing fairly common to the cache groups is a block of code to look to see when the cache was last changed, and if there isn't one, to set it for the current microtime(). It appears in 8 different places in core. This adds a new helper `wp_cache_get_last_changed` to DRY things up a bit.
Since `wp-includes/cache.php` isn't guaranteed to be loaded, this new function is in `wp-includes/functions.php`

REST API endpoints for your WordPress content. These endpoints provide machine-readable external access to your WordPress site with a clear, standards-driven interface, allowing new and innovative apps for interacting with your site. These endpoints support all of the following:
- Posts: Read and write access to all post data, for all types of post-based data, including pages and media.
- Comments: Read and write access to all comment data. This includes pingbacks and trackbacks.
- Terms: Read and write access to all term data.
- Users: Read and write access to all user data. This includes public access to some data for post authors.
- Meta: Read and write access to metadata for posts, comments, terms, and users, on an opt-in basis from plugins.
- Settings: Read and write access to settings, on an opt-in basis from plugins and core. This enables API management of key site content values that are technically stored in options, such as site title and byline.
Love your REST API, WordPress! The infrastructure says, "Let's do lunch!" but the content API endpoints say, "You're paying!"

In the process of making this adjustment:

* The recently introduced `wp_object_type_exists()` function and the restriction on object type has been removed.

* Use `wp_convert_hr_to_bytes()` when parsing the value of the `memory_limit` setting because it can be a shorthand or an integer value.
* Introduce `wp_raise_memory_limit( $context )` to raise the PHP memory limit for memory intensive processes. This DRYs up some logic and includes the existing `admin_memory_limit` and `image_memory_limit` filters. The function can also be used for custom contexts, the `{$context}_memory_limit` filter allows to customize the limit.
* Introduce `wp_is_ini_value_changeable( $setting )` to determine whether a PHP ini value is changeable at runtime.

`Pragma` is supposed to be a request header, but we've been including it in responses since the beginning of time.
This is a relic dating all the way back to b2, probably originally added because Internet Explorer version 5 and earlier didn't understand the `Cache-Control` header in responses, but they did (incorrectly) obey the `Pragma` header.
Internet Explorer 6 and 7 will obey the `Pragma` response header only if no other cache-related response headers are present (in our case, they are always present), and all other browsers ignore the `Pragma` response header.

Move the REST API JSONP callback validation check into a separate function named `wp_check_jsonp_callback()`. This allows plugins to use the built-in validation when handling JSONP callbacks.

At the time of introduction in 3.8, there were not good system fonts common to all platforms at the time. In the years since, Windows, Android, OS X, iOS, Firefox OS, and various flavors of Linux have all gotten their own (good) system UI fonts.
There will definitely be visual bugs, mainly around alignment and spacing; these should be documented and reported on the ticket and fixed more atomically so that our current and future selves have a better understanding of what happened and why.

To improve the performance of `wp_upload_dir()` the result of `wp_mkdir_p()` was stored in a persistent cache, introduced in [36565]. But this becomes an issue when WordPress is scaled horizontally. You may end up caching a value for a server where the directory doesn't exist which will prevent further uploads on other servers because of the persistent cache.
The fix is to use a non-persistent cache.

The `WP_INSTALLING` constant is a flag that WordPress sets in a number of
places, telling the system that options should be fetched directly from the
database instead of from the cache, that WP should not ping wordpress.org for
updates, that the normal "not installed" checks should be bypassed, and so on.
A constant is generally necessary for this purpose, because the flag is
typically set before the WP bootstrap, meaning that WP functions are not yet
available. However, it is possible - notably, during `wpmu_create_blog()` -
for the "installing" flag to be set after WP has already loaded. In these
cases, `WP_INSTALLING` would be set for the remainder of the process, since
there's no way to change a constant once it's defined. This, in turn, polluted
later function calls that ought to have been outside the scope of site
creation, particularly the non-caching of option data. The problem was
particularly evident in the case of the automated tests, where `WP_INSTALLING`
was set the first time a site was created, and remained set for the rest of the
suite.
The new `wp_installing()` function allows developers to fetch the current
installation status (when called without any arguments) or to set the
installation status (when called with a boolean `true` or `false`). Use of
the `WP_INSTALLING` constant is still supported; `wp_installing()` will default
to `true` if the constant is defined during the bootstrap.
