Another chapter in the Storied Annals of Weird `in_array()` Behavior:
`in_array( 4, array( "4-cool-dudes" ) );` resolves to `true`, such that
`is_page( 4 )` was returning true for posts with the name `'4-cool-dudes'`.
We work around this behavior by ensuring that values passed to the `is_`
methods are cast to strings before the `in_array()` checks. ID checks still
work as expected; see #24674.

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.

Lazyloading for comment meta and term meta, introduced into `WP_Query` in
4.4, used flags - `updated_term_meta_cache` and `updated_comment_meta_cache` -
in an attempt to prevent cache priming from happening more than once per query
object. This technique was mostly effective, but not entirely efficient, since
the flag didn't prevent the `lazyload_*_meta` callbacks from running. The
obvious solution - removing the filter callback after it'd be run once - was
dismissed for 4.4 because of concerns that `remove_filter()` could disable
lazyloading too generally in the context of nested queries, due to the way
`_wp_filter_build_unique_id()` doesn't always build sufficiently unique IDs for
similar objects. However, further testing shows that this concern is only valid
in a very small subset of cases, while the cost of keeping the query objects in
memory, via the `$wp_filter` global, is quite significant. As such, this
changeset removes the flags in favor of the `remove_filter()` technique.
See #35454, #35816.

This provides better parity with `get_queried_object()`, which will return the

The introduction of negative search terms in 4.4 [34934] introduced the
possibility that the ORDER BY clause of a search query could be assembled in
such a way as to create invalid syntax. The current changeset fixes this by
ensuring that the ORDER BY clause corresponding to the search terms is
excluded when it would otherwise be empty.

Twelve years later, after no fewer than three themes have intentionally implemented popup comments in their functionality, before being abandoned for at least the last six years, we've reached a time where we can put this era behind us. A time when we can remove comment popup functionality from WordPress.

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.

Lazy-loading logic is moved to a method on `WP_Query`. This makes it possible
for comment feeds to take advantage of metadata lazyloading, in addition to
comments loaded via `comments_template()`.

[34529] introduced lazyloading for the metadata belonging to terms matching
posts in the main `WP_Query`. The current changeset improves this technique
in the following ways:
* Term meta lazyloading is now performed on the results of all `WP_Query` queries, not just the main query.
* Fewer global variable touches and greater encapsulation.
* The logic for looping through posts to identify terms is now only performed once per `WP_Query`.

Previously, unattached attachments would have unsightly `/?attachment_id=1` URLs. As we've moved away from attachments being specifically attached to posts, instead being Media items, this has made the unattached URLs a more common occurrence.

Setting the default value of the `queried_object_id` property to `0` meant
that, when called early enough in the WP bootstrap, `get_queried_object()`
could short-circuit the normal query by fooling it into thinking that the
request was for a page with id 0. Setting the default value to `null` instead
avoids this problem.
