* Autosaved changes made on top of `auto-draft` changesets get written on top of the `auto-draft` itself, similar to how autosaves for posts will overwrite post drafts.
* Autosaved changes made to saved changesets (e.g. `draft`, `future`) will be placed into an autosave revision for that changeset and that user.
* Opening the Customizer will now prompt the user to restore their most recent auto-draft changeset; if notification is dismissed or ignored then the auto-draft will be marked as dismissed and will not be prompted to user in a notification again.
* Customizer will no longer automatically supply the `changeset_uuid` param in the `customize.php` URL when branching changesets are not active.
* If user closes Customizer explicitly via clicking on X link, then autosave auto-draft/autosave will be dismissed so as to not be prompted again.
* If there is a changeset already saved as a `draft` or `future` (UI is forthcoming) then this changeset will now be autoloaded for the user to keep making additional changes. This is the linear model for changesets.
* To restore the previous behavior of the Customizer where each session started a new changeset, regardless of whether or not there was an existing changeset saved, there is now a `customize_changeset_branching` hook which can be filtered to return `true`.
* `wp.customize.requestChangesetUpdate()` now supports a second with options including `autosave`, `title`, and `date`.
* The window `blur` event for `customize.php` has been replaced with a `visibilitychange` event to reduce autosave requests when clicking into preview window.
* Adds `autosaved` and `branching` args to `WP_Customize_Manager`.
* The `changeset_uuid` param for `WP_Customize_Manager` is extended to recognize a `false` value which causes the Customizer to defer identifying the UUID until `after_setup_theme` in the new `WP_Customize_Manager::establish_loaded_changeset()` method.
* A new `customize_autosaved` query parameter can now be supplied which is passed into the `autosaved` arg in `WP_Customize_Manager`; this option is an opt-in to source data from the autosave revision, allowing a user to restore autosaved changes.

This will send sidebars through three levels of mapping:
1. If both themes have only one sidebar, that gets mapped.
2. If both themes have sidebars with the same slug, they get mapped.
3. Sidebars that (even partially) match slugs from a similar kind of sidebar will get mapped.
Finally, if the theme has previously been active and we have a record of its
sidebar configuration then, any unmapped sidebar will be restored to its
previous state.

The main purpose of the new function at this point is to ensure that the `WP_Network::$blog_id` property is always set. Magic getters in the class have been adjusted to auto-fill the property when it is accessed and empty. Furthermore the function encapsulates logic that was previously part of `ms_load_current_site_and_network()` and has been replaced with a call to the function now.

Generally, duplicate terms returned by a term query are eliminated in PHP,
after the database query takes place. This technique doesn't work properly
when the query parameters specify the `number` of results, since the results
of a `SELECT ... LIMIT x...` query may be deduplicated to a count less than
`x`. In these cases, we force the original query to be `DISTINCT`.

* Code editor is integrated into the Theme/Plugin Editor, Additional CSS in Customizer, and Custom HTML widget. Code editor is not yet integrated into the post editor, and it may not be until accessibility concerns are addressed.
* The CodeMirror component in the Custom HTML widget is integrated in a similar way to TinyMCE being integrated into the Text widget, adopting the same approach for integrating dynamic JavaScript-initialized fields.
* Linting is performed for JS, CSS, HTML, and JSON via JSHint, CSSLint, HTMLHint, and JSONLint respectively. Linting is not yet supported for PHP.
* When user lacks `unfiltered_html` the capability, the Custom HTML widget will report any Kses-invalid elements and attributes as errors via a custom Kses rule for HTMLHint.
* When linting errors are detected, the user will be prevented from saving the code until the errors are fixed, reducing instances of broken websites.
* The placeholder value is removed from Custom CSS in favor of a fleshed-out section description which now auto-expands when the CSS field is empty. See #39892.
* The CodeMirror library is included as `wp.CodeMirror` to prevent conflicts with any existing `CodeMirror` global.
* An `wp.codeEditor.initialize()` API in JS is provided to convert a `textarea` into CodeMirror, with a `wp_enqueue_code_editor()` function in PHP to manage enqueueing the assets and settings needed to edit a given type of code.
* A user preference is added to manage whether or not "syntax highlighting" is enabled. The feature is opt-out, being enabled by default.

technologies which the current item within a set of items is. While the admin menu

adding `aria-current="page"` to the sub-items gives an important feedback to

This introduces the following meta capabilities:
* `activate_plugin`
* `deactivate_plugin`
* `deactivate_plugins`
The singular `activate_plugin` and `deactivate_plugin` capabilities are used along with the corresponding plugin name when
determining whether or not a user can activate or deactivate an individual plugin.
The plural `deactivate_plugins` capability is used in place of the existing `activate_plugins` capability when determining
whether a user can deactivate plugins.
Each of these new meta capabilities map to the existing `activate_plugins` primitive capability, which means there is no
change in existing behaviour, but plugins can now filter the capabilities required to activate and deactivate individual
plugins.

The new meta capabilities are called `install_languages` and `update_languages`. Prior to this change, there were no proper capability checks applied. Instead only the filesystem and related constants were checked, and for actual permissions a rather vague fallback was used where a user needed to have at least one of the other updating capabilities. In addition to being generally more verbose, the new capabilities make it possible for example to allow a user to update languages, but nothing else. By default they fall back to the original way of how they were handled.

There were a handful of files with an underscore in the name, which violated our naming scheme, and caused problems for anyone how enforced the scheme on their own systems.
This commit renames all of the files to the correct camelCase scheme.

Passing a non-null value to the filter will prevent the uploaded file from being moved to the uploads directory for any of the functions leveraging `_wp_handle_upload()`, such as `wp_handle_upload()` or `wp_handle_sideload()`.
Error reporting related to the file being moved will also be skipped.

This adds this previously Multisite-only functionality to single site installations too. This change prevents accidental or erroneous email address changes from potentially locking users out of their site.

Twemoji 2.3.0 has a rendering issue in Safari, emoji can sometimes be followed by U+FEOF (which is just a flag meaning "render the preceding character as emoji).
Twemoji wasn't catching this character correctly, and Safari rendered it incorrectly.
Twemoji 2.5.0 resolves this issue.

This will send nav menu locations through three levels of mapping:
1. If both themes have only one location, that gets mapped.
2. If both themes have locations with the same slug, they get mapped.
3. Locations that (even partially) match slugs from a similar kind of menu location will get mapped.
Menu locations are mapped for Live Previews in the Customizer and during theme switches.

The following tests were never executed as they have `@depends` annotations which means they get skipped because the `test_video_shortcode_body()` test has not run by the time they run. Re-ordering the test methods fixes this.

* `test_wp_video_shortcode_with_bad_attr()`
* `test_wp_video_shortcode_attributes()`
* `test_wp_video_shortcode_youtube_remove_feature()`

Fixes a visual glitch visible on Ubuntu. WordPress uses system fonts and they have
different metrics across operating systems. Uses screen-reader-text as a more
solid way to visually hide text.

While site administrators cannot generally edit users in multisite, they have always been able to change the roles of users on their site. In the REST API however, this has not been possible so far. This changeset brings parity with how it is handled in the administration panel: A REST request to edit only a user's roles succeeds correctly, while a REST request to edit any further details of a user fails.

Under certain circumstances, it can be necessary that a user should not be added to a site, beyond the restrictions that WordPress core applies. With the new `can_add_user_to_blog` filter, plugin developers can run custom checks and return an error in case of a failure, that will prevent the user from being added.
The user-facing parts and the REST API route that interact with `add_user_to_blog()` have been adjusted accordingly to provide appropriate error feedback when a user could not be added to a site. Furthermore, two existing error feedback messages in the site admin's "New User" screen have been adjusted to properly show inside an error notice instead of a success notice.

There are now 3 places where we call out to the REST API from within wp-admin. This commit introduces a small library to allow overriding these calls, centralize nonce-passing logic, and eliminate the need to pass a full REST URL down to client code (this last feature is not yet used and will be explored in a separate ticket).

The `settings_previewed` property eliminates the need for the Customizer components from having to look at global `doing_ajax` state. This is in particular needed when saving settings, as some settings will short-circuit the update operation if they detect no changes are introduced. This is also needed for low-level integrations with the Customizer, such as in REST API endpoints under development.

`WP_Comment_Query` always queries runs an ID query, and so is unaffected
by the 'fields' parameter. As such, 'fields' can be ignored when building
a cache key for the results of the ID query.
