a027edc277 Comments: The year is 2003. Permalinks are a new thing and everyone's using Blogger. It's a time when opening a modal window in JavaScript to view a section of a website is not a completely weird thing, although many users get annoyed by it. b2 has recently become WordPress, and with it comes a bunch of functionality that will become stale over the next decade, remnants of simpler times.
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.

If this breaks the internet, I'll eat my hat.

83c3e3e00e Embeds: Add oEmbed provider support.
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.

654eeb3785 Improve lazyloading of comment meta in WP_Query loops.
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()`.

This new technique parallels the termmeta lazyloading technique introduced in
[34704].

db880777f4 Improve lazyloading of term metadata in WP_Query loops.
[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`.

cf173408cd Permalinks: Add pretty permalinks for unattached attachments.
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.

1a203b5328 Better default values in WP_Query::get_queried_object().
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.

7dcb041d5a More careful type conversion in WP_Query is_*() methods.
`is_array( 1, '1-foo' )` returns true, which means that `is_page( 1 )`
was returning true when on a page with the slug '1-foo'. We avoid this odd
behavior by casting the queried object ID to a string before testing against
the value passed to the conditional function.

This also helps to avoid a problem where an arbitrary value for `$page` would
cause `is_page( $page )` to return true if the query had been manipulated by
a plugin to show that the current page's ID is 0.

90639872e8 In WP_Query::get_queried_object(), avoid PHP notices when is_tax is paired with an empty tax_query.
It's possible to have an empty `tax_query` and `is_tax=true` when the initial
query contains a taxonomy var (and is processed as such during
`WP_Query::parse_query()`) but the taxonomy var is unset during a 'parse_query'
callback. While this kind of behavior is not necessarily something we need to
support, we should continue to avoid PHP notices in such cases, as we did prior
to WP 4.1.

7bde88d02e Modify `meta_query orderby syntax to use array keys as clause "handles".
The implementation of `meta_query` orderby introduced in [31312] put clause
identifiers into a 'name' parameter of the clause. For greater clarity, this
changeset updates the syntax to use the associative array key used when
defining `meta_query` parameters, instead of the 'name' parameter.

55dafd966b When querying for a specific post, allow posts with a non-public status to be returned as long as that status is specified.
This makes it possible to, for example, retrieve a specific post using the
`p` parameter of `WP_Query`, even if the post is in the Trash, by including
the `post_status=trash` parameter.

ca30c725a0 Improve support for ordering WP_Query results by postmeta.
`WP_Meta_Query` clauses now support a 'name' parameter. When building a
`WP_Query` object, the value of 'orderby' can reference this 'name', so that
it's possible to order by any clause in a meta_query, not just the first one
(as when using 'orderby=meta_value'). This improvement also makes it possible
to order by multiple meta query clauses (or by any other eligible field plus
a meta query clause), using the array syntax for 'orderby' introduced in [29027].
