`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.

Moving to load.php introduces parity with other commonly evaluated `is_*()` functions such as `is_admin()` or `is_multisite()`. It also makes `is_ssl()` available much earlier in the loading process, such as for use in drop-ins like advanced-cache.php.

Similar to `get_current_blog_id`, this can be used to get the ID of the `$current_site` global. If not available, it will fallback to the main network ID. In single site, this will return 1.

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.
Extremely Important Note: If you send JSONP in your custom response, make sure you prefix the response with `/**/`. This will mitigate the Rosetta Flash exploit. You should also send the `X-Content-Type-Options:nosniff` header, or even better, use the REST API infrastructure.

Rejoice, for your admins will feel more native to your surrounding computing environment and likely load faster, especially when offline, as they no longer have to talk to The Google Overlord.
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.
The style remains registered, as it is almost certainly in use by themes and plugins.

Unicode 8 added `U+1F644`, "Face with Rolling Eyes", which matches our `:roll:` smiley. Continuing our ever present quest to rid the world of legacy smilies, we now translate that smiley into its emoji form.
Sadly, `:mrgreen:` remains sorely under-represented in the Unicode standard, I'm inclined to think that we should buy a voting membership of the Unicode Consortium, in order to rectify that situation. (Personally, I'm hoping for a green skin tone modifier.)

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.

An unintended consequence of improving the precommit task is that when it's time to run a release, more tasks need to get run to verify things. This adds a prerelease task to help fix that situation. grunt prerelease should include tasks that verify the code base is ready to be released to the wild and find all the tears on the mausoleum floor and help Blood stain the Colosseum doors.

- Cache the output in non-persistent cache.
- Cache the result from `wp_mkdir_p()` in persistent cache (when present).
- Introduce `wp_get_upload_dir()` for use when not uploading files. It is equivalent to `wp_upload_dir()` but does not check for the existence or create the upload directory.
- Change tests to use the non-cached `_wp_upload_dir()`. They change options on the fly (should never be used in production) to simulate different environments.
- Introduce `_upload_dir_no_subdir()` and `_upload_dir_https()` to facilitate testing. These use the proper `upload_dir` filter to simulate different environments.

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.
