With the introduction of user-specific languages in [38705] it's necessary to be able to switch translations on the fly. For example emails should be sent in the language of the recipient and not the one of the current user.
This introduces a new `WP_Locale_Switcher` class which is used for switching locales and translations. It holds the stack of locales whenever `switch_to_locale( $locale )` is called. With `restore_previous_locale()` you can restore the previous locale. `restore_current_locale()` empties the stack and sets the locale back to the initial value.
`switch_to_locale()` is added to most of core's email functions, either with the value of `get_locale()` (site language) or `get_user_locale()` (user language with fallback to site language).

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.
This was previously committed in [38859] but got reverted in [38862] and [38863]. To fix the previous issues, `wp_list_sort()` supports now an additional argument to preserve array keys via `uasort()`.

Previously we ensured that the entry points to WordPress were parsable by PHP4 in order to display a friendly not-supported-php error message.
However, for the last two years the main entry points have not actually parsed, and we've only added extra parse errors since it last worked in 3.9, so it's time we just remove this 'feature'.
The PHP version checks are still there for PHP 5.0/5.1, and so it's inplace when we eventually drop PHP 5.2 support.

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!"

After [38364], the inclusion of `class-wp-locale.php` was changed from a `require_once()` to a `require()`. This caused problems for anything that called `load_text_domain_early()` prior to the `require()` but didn't bail, as it was now being `require()`-ed a second time.
With the use of `require_once()`, it doesn't really matter where it's loaded, so it has been moved next to the related `l10n.php` load.

* `wp-vendor/autoload_52.php` is included at the top of `wp-settings.php` - no changes need to be made to unit tests to include the autoloader
* An avalanche of `require()` and `require_once()` calls that loaded class files have been removed from the codebase.

We favor these files instead:

* src/wp-vendor/composer/autoload_real_52.php

When new PHP classes are added to the codebase, simply run `composer install` or `composer update` from the project root to update the autoloader.

First added in [37588] and later modified in [38224], the idea was to ensure that filters/actions added before `advance-cache.php` would not disappear if `advance-cache.php` overloaded the filters/actions with code such as `$wp_filter = array()`. This is an edge case and one that there is no documented case of existing.
This restores the behavior from WordPress 4.5 and before. It is strongly encouraged that developers using `advance-cache.php` to use the Plugins API that is available before the loading of `advance-cache.php` rather than directly interacting with any of the globals.

[37588] added methods to backup the plugin globals, for ensuring that advanced cache drop-ins don't overwrite hooks that've been added earlier in the load process.
The method for restoring the plugin globals wasn't compatible with the implementation of `WP_Hook` in #17817. `WP_Hook` implements `ArrayAccess`, so `_restore_plugin_globals()` was treating it as an array, and inadvertantly overwriting the `WP_Hook` object with a plain array.
To avoid having to re-write this code as part of #17817, we now use `add_filter()` to restore any hooks that were added by cache drop-ins, which `WP_Hook` correctly supports.

Non web interfaces with WordPress (such as wp-cli) need to be able to bypass certain checks in the bootstrap process. This introduces three new filters to allow for those checks to be skipped.
1. Provides a way of forcefully bypassing wp_maintenance().
2. Provides a way of forcefully bypassing wp_debug_mode(). See https://github.com/wp-cli/wp-cli/issues/177
3. Provide a way of forcefully skipping loading wp-content/advance-cache.php. See https://github.com/wp-cli/wp-cli/pull/164
These filters should not be used by plugins (in fact, they run before plugins are loaded, so they can't be used by plugins). In general, they should only be used in non-web interactions with WordPress.

Comment and term meta lazyloading for `WP_Query` loops, introduced in 4.4,
depended on filter callback methods belonging to `WP_Query` objects. This meant
storing `WP_Query` objects in the `$wp_filter` global (via `add_filter()`),
requiring that PHP retain the objects in memory, even when the local variables
would typically be expunged during normal garbage collection. In cases where a
large number of `WP_Query` objects were instantiated on a single pageload,
and/or where the contents of the `WP_Query` objects were quite large, serious
performance issues could result.
We skirt this problem by moving metadata lazyloading out of `WP_Query`. The
new `WP_Metadata_Lazyloader` class acts as a lazyload queue. Query instances
register items whose metadata should be lazyloaded - such as post terms, or
comments - and a `WP_Metadata_Lazyloader` method will intercept comment and
term meta requests to perform the cache priming. Since `WP_Metadata_Lazyloader`
instances are far smaller than `WP_Query` (containing only object IDs), and
clean up after themselves far better than the previous `WP_Query` methods (bp
only running their callbacks a single time for a given set of queued objects),
the resource use is decreased dramatically.
See [36525] for an earlier step in this direction.

For the past 6 years, WordPress has operated as an oEmbed consumer, allowing users to easily embed content from other sites. By adding oEmbed provider support, this allows any oEmbed consumer to embed posts from WordPress sites.
In addition to creating an oEmbed provider, WordPress' oEmbed consumer code has been enhanced to work with any site that provides oEmbed data (as long as it matches some strict security rules), and provides a preview from within the post editor.
For security, embeds appear within a sandboxed iframe - the iframe content is a template that can be styled or replaced entirely by the theme on the provider site.

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.
