WordPress has supported custom page templates for over 12 years, allowing developers to create various layouts for specific pages.
While this feature is very helpful, it has always been limited to the 'page' post type and not was not available to other post types.
By opening up the page template functionality to all post types, we continue to improve the template hierarchy's flexibility.
In addition to the `Template Name` file header, the post types supported by a template can be specified using `Template Post Type: post, foo, bar`.
When at least one template exists for a post type, the 'Post Attributes' meta box will be displayed in the back end, without the need to add post type support for `'page-attributes'`. 'Post Attributes' can be customized per post type using the `'attributes'` label when registering a post type.

Like its predecessor (`sanitize_text_field()`), `sanitize_textarea_field()` is a helper function to sanitise user input. As the name suggests, this function is for sanitising input from `textarea` fields - it strips tags and invalid UTF-8 characters, like `sanitize_text_field()`, but retains newlines and extra inline whitespace.

The `blog_details` filter is applied when full details are requested from `get_blog_details()`.

Fixes bug where an invalid Last-Modified value would be returned in feed requests for sites that had 0 items to return. Comment or post feeds will now return the current timestamp as the Last-Modified header value. Example: a request for the comments feed for a site without any comments.
Replaced use of the local static variable `$cache_lastcommentmodified` to store the modified date in `get_lastcommentmodified()` with the Object Cache API. The `get_lastcommentmodified()` function returns early if there is a cached value and returns `false` if there where no comments found. Introduced `_clear_modified_cache_on_transition_comment_status()` to flush the `lastcommentmodified` cache key when a comment enters or leaves approval status. In `get_lastpostmodified()` return early if there is a cached value and return `false` if there are no posts found.

This functionality was originally added in [38858], using `symlink()` to put a link to the theme in WordPress' `themes` directory. Unfortunately, not all installs have write access to the `themes` directory, causing unit tests to fail.
The new method is to add the test theme directory to `$wp_theme_directories`, and fix the handful of tests that don't expect `$wp_theme_directories` to have multiple entries.
The test install/bootstrap routines now also check that `WP_DEFAULT_THEME` is defined, in case the tests are being run on a system that hasn't upgraded its' `wp-tests-config.php`.

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!"
