In addition to MySQL, WordPress also supports MariaDB for databases. This makes changes to the local Docker environment to allow MariaDB to be used instead, if desired.
The `LOCAL_DB_TYPE` environment variable will now be used to determine which type of database container to use. This will default to `mysql`, but will also accept `mariadb`.
The `LOCAL_MYSQL` environment variable (which previously held the version of MySQL to use) has been replaced with the new, more generic `LOCAL_DB_VERSION` environment variable.
This change will make it possible to perform automated testing on a wider array of supported database types and versions.

This will help catch issues with Ajax related functionality on multisite.
A few tests have also been marked as `skipWithMultisite()` as they require network admin level capabilities when performing the same operations on a multisite install.

This introduces a new GitHub Action workflow to generate a code coverage report when running the PHPUnit test suite as both a single and multisite install.
The workflow will run once per week on Sunday at 00:00 UTC.
For now, the reports are not submitted anywhere, but they will be uploaded to the workflow run as ZIP file artifacts where they will persist for 90 days.
Making code coverage reports more readily available will hopefully better highlight areas of Core with poor coverage, and encourage more contributors to help increase test coverage of those areas.

each queried post type. This ensures that private posts appear in search and

Previously, `1.0.0` was used for the version. This is inconsistent with the versioning used in the other default themes, which use use X.X and not X.X.X.
This change corrects all `1.0.0` occurrences to `1.0`, and adds the additional context of `Twenty Twenty-One` to avoid confusion with `WordPress 1.0`.

* Expands the capabilities of `wp_filter_content_tags()` to add the attribute to iframe tags if enabled.
* Modifies the default behavior of `wp_lazy_loading_enabled()` so that it returns `true` for `iframe` tags.
* Introduces a `wp_iframe_tag_add_loading_attr()` function.
* Introduces a `wp_iframe_tag_add_loading_attr` filter.
Like for images, the attribute is only added to iframes which have both `width` and `height` specified (see related #50367).

When SimplePie parses HTTP headers, it combines multiple values for the same header into a comma-separated string. `WP_SimplePie_File` overrides the parsing, but was leaving them as an array instead.
That lead to a fatal error in PHP 8, because other parts of the codebase ended up passing an array to a function that expected a string.

In PHPUnit 3.6.x, `exclude` and `file` paths were required to be relative to the checkout root. This changed in PHPUnit 4 when the path requirements were changed require them to be relative to the configuration file.
Since PHPUnit 3.6.x is only used to test on PHP 5.2 in older branches and is no longer supported, these can be safely removed from the configuration file.

The test reporter uses the hidden `.svn` or `.git` directories to determine which changeset to send to WordPress.org along with the test report.
Because the GitHub Action workflow builds and prepares WordPress in a preceding job to share with each test job, the `.git` directory is missing (it is purposefully not included to limit artifact size).
This re-establishes the directory as a checkout of the `wordpress-develop` repository so that test results can be reported correctly.

In the current state, the workflows run regardless of the repository context. This results many needless workflow runs that waste resources.
Workflow runs for private repositories are not free (accounts have a finite allotment of minutes for private repositories). This becomes problematic in private repositories that also mirror the WordPress develop repository, as any workflow runs will draw from a user’s or organization’s allotted action minutes.
Without blanket disabling the workflow manually for all event triggers, or modifying the workflow files in the forked/mirrored repository, there is no way to tune when the workflows run.
This change introduces a conditional statement into all GitHub Action workflows that prevents them from running on forked/mirrored repositories that are not `wordpress-develop`, except when a pull request is being submitted to that repository.
The exception to this is the Welcome workflow that posts a helpful message to first time contributors to `wordpress-develop`. This message is specific to this repository, so should only run when a PR is submitted to that repository.

Appveyor was added to Core in [44594] to ensure that NPM and the WordPress build tools continue to work correctly on Windows systems as changes are made. Using an additional service for this was required at the time, TravisCI did not support testing on Windows.
[49162] introduced a GitHub Action workflow that performed the same testing. Since all automated testing is moving to GitHub Actions, using Appveyor is no longer necessary, and it’s preferable to have all automated testing in one location as much as possible.
