* Introduce `try_gutenberg_learn_more_link` filter that allows hosts or site owners to change the link, to provide extra information about Gutenberg, specific to their service.
* Only display the "Install" buttons if we're able to directly write to disk to install the plugins.
* Make sure the "Dismiss" link works correctly.

Reverting this for 4.9. It will be added back in a future version of WordPress. This doesn't mean that you shouldn't be trying Gutenberg, just that it isn't ready for a call out to a larger audience. But if you are the type to read commit messages, https://github.com/WordPress/gutenberg could use your pull requests and comments on issues.

* Edits to active plugins which cause PHP fatal errors will no longer auto-deactivate the plugin. Supersedes #39766.
* Introduce sandboxed PHP file edits for active themes, preventing accidental whitescreening of a user's site when introducing a fatal error.
* After writing a change to a PHP file for an active theme or plugin, perform loopback requests on the file editor admin screens and the homepage to check for fatal errors. If a fatal error is encountered, roll back the edited file and display the error to the user to fix and try again.
* Introduce a secure way to scrape PHP fatal errors from a site via `wp_start_scraping_edited_file_errors()` and `wp_finalize_scraping_edited_file_errors()`.
* Moves file modifications from `theme-editor.php` and `plugin-editor.php` to common `wp_edit_theme_plugin_file()` function.
* Refactor themes and plugin editors to submit file changes via Ajax instead of doing full page refreshes when JS is available.
* Use `get` method for theme/plugin dropdowns.
* Improve styling of plugin editors, including width of plugin/theme dropdowns.
* Improve notices API for theme/plugin editor JS component.
* Strip common base directory from plugin file list. See #24048.
* Factor out functions to list editable file types in `wp_get_theme_file_editable_extensions()` and `wp_get_plugin_file_editable_extensions()`.
* Scroll to line in editor that has linting error when attempting to save. See #41886.
* Add checkbox to dismiss lint errors to proceed with saving. See #41887.
* Only style the Update File button as disabled instead of actually disabling it for accessibility reasons.
* Ensure that value from CodeMirror is used instead of `textarea` when CodeMirror is present.
* Add "Are you sure?" check when leaving editor when there are unsaved changes.
Supersedes [41560].

Previously, changing the post thumbnail of a published post in the edit screen
would immediately apply the change, rather than waiting for the post to be
saved before applying the update. This could lead to someone unintentionally
editing the post thumbnail on a published post, and made it impossible to
preview changes to post thumbnails on published posts before saving the change.
This introduces a new Ajax handler, `wp_ajax_get_post_thumbnail_html()` to
retrieve the HTML for the post thumbnail meta box without updating the post
meta value for `_thumbnail_id`. It also allows post thumbnail changes to be
previewed by passing the `_thumbnail_id` as a query variable to the preview
screen and adding a new filter, `_wp_preview_post_thumbnail_filter()`, which
gets applied to `get_post_metadata` during the post preview process.

Gone are the days of isolation and feelings of "meh", brought on by The Bleak Screen of Sadness. For a shiny knight has arrived to usher our plugins and themes along their arduous journey of installation, updates, and the inevitable fate of ultimate deletion.

Color scheme selection on your own profile page gives you a preview and autosaves the selection.
Also introduces the usage of a preprocessor for core files, namely Sass. For 3.8, we will not expand its implementation past the color schemes. This does require Ruby as well as Sass 3.3.0+ due to the usage of the sourcemap option.
Note that only the default color scheme is available when running out of src. Use build to test the rest as well as the color picker.

* Much simpler PHP API
* Cleaner and more Backbone-y JS API
* Consequently, does batch queries; this now scales up to hundreds of revisions
Currently missing, but much easier considering the cleaned up base:
* Compare two mode
* RTL

This implements a new revisions ui using Backbone and preserves all the old methods of "integration" so the change should be transparent to plugins using revisi
ons with CPTs.
This is the first pass and so there are a number of things still to be resolved, more details in the ticket. Feedback welcomed.
