Visible `<label>` elements benefit all users. The `placeholder` attribute should not be used as a replacement for visible labels.
Instead, it's supposed to be used only for a short hint to aid users with data entry e.g. a sample value or a brief description of the expected format.
Screen readers may not announce a `placeholder` attribute at all. Other users may suffer from the lack of a visible label and a placeholder used as replacement, for example:
- users with cognitive disabilities may have trouble remembering what the filled field does
- speech recognition users cannot see the name they can speak to set focus on the field
- low-vision users with high text-size may not be able to see the whole placeholder even when it's visible, if its value is clipped by the edge of the input

Each item that `Walker_Nav_Menu_Checklist` displays is accompanied by several hidden `<input/>` fields that specify default values for each item when added to a menu. These values are passed in JavaScript to the AJAX call triggered when an item is added to a menu.
The hidden field for the title attribute field incorrectly had an underscore instead of a hyphen. Because of this, it was impossible to supply a default value for the Title Attribute field of a nav menu item.

User interface controls that use only icons aren't ideal for many users.
Universal icons are rare. Icons must communicate meaning but their actual meaning varies depending on many factors including the users cultural background.
Moreover, users with cognitive impairments and speech recognition users need interface controls with visible text to be able to operate them.

This change introduces a new Composer script, `compat` that will scan the codebase for (detectable) potential PHP compatibility issues using the `PHP_CodeSniffer` and a custom ruleset based off of the `PHPCompayibilityWP` ruleset (`phpcompat.xml.dist`).
The command will be run as a separate job within each Travis build. While many compatibility issues and false positives have already been corrected in this commit and other Trac tickets, there are still some remaining. For that reason, the job is allowed to fail while the remainder of the potential compatibility issues are investigated and addressed. After those are resolved, the job should be set as required to pass to help prevent new compatibility issues from being introduced.

The PHP native JSON extension has been bundled and compiled with PHP by default since version 5.2.0. Because the minimum version of PHP required by WordPress is now 5.6.20 (see #46594 and [45058]), JSON extension related polyfills and backwards compatibility code can now be removed.
This change removes code that supported JSON related functionality on older versions of PHP. This includes (but is not limited to) checks that `json_last_error()` exists, checking and setting the `JSON_UNESCAPED_SLASHES` and `JSON_PRETTY_PRINT` constants if not previously defined, and deprecating the `_wp_json_prepare_data()` function (which was 100% workaround code).

As part of the Multisite installation process, a `blog_versions` table is created. This table is never read from (except immediately prior to updating it), it's only ever inserted into or updated. It is not used to determine which blogs need to be upgraded.
This table was introduced in 3.0 when the WPMU schema was merged #11644 and it appears the table has never been used in core and is therefore redundant and may as well be removed.

Currently there is there a table in multisite called blog_versions. All this table stores is the database version as number and the date updated. With plans to add site meta in #37923 this new table should be used. This has a number of benefits, including functions to CRUD these values in the database. Once this data is in the blogmeta, table, the blog_versions table can be removed all together. If require a SQL view can be used blog_versions from data stored in blogmeta.

The `implode()` function accepts two. parameters, `$glue` and `$pieces`. For historical reasons, these parameters have been accepted in any order, though it was recommended that the documented order of `$glue, $pieces` be used.
Starting in PHP 7.4, specifying the parameters in the reverse order will trigger a deprecation notice with the plan to remove this tolerance in PHP 8.0.
This change fixes the occurrences of reversed arguments in Core with the exception of those contained in included external libraries. These will be handled separately.

best option is to avoid unnecessary abbreviations when possible. In the other cases,
use an `<abbr>` element (which provides a hint to user agents on how to announce
and display the abbreviation) and provide an expansion in plain text on first use.
- `readme.html`: improves abbreviations and removes unnecessary `title` attributes
- options-general: removes unnecessary abbreviations and improves the remaining ones
- customizer schedule changeset date: removes unnecessary abbreviations and improves the remaining ones
- posts table date: uses a `span` element instead of an `abbr` element because this is not an abbreviation
