How does it look?
The coreCoreCore is the set of software required to run WordPress. The Core Development Team builds WordPress. auto-updates feature already exists for years in WordPress. WP 5.6 only introduces a new user interface to make it easier to opt-in to automatic updates for major versions.
By default, WordPress auto-updates itself, but only for minor releases. Developers can already opt-in to major releases auto-updates by setting up the existing WP_AUTO_UPDATE_CORE constant to true or by using the allow_major_auto_core_updates existing filterFilterFilters are one of the two types of Hooks https://codex.wordpress.org/Plugin_API/Hooks. They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output..
With WordPress 5.6, it’s possible for website administrators to opt-in/out to automatic updates for major versions, using a specific interface located on the Updates screen:
How does it work?
This settings section basically adds a checkbox to allow administrators to opt-in to major core auto-updates. But it also checks for any existing constant or filter to see if the checkbox should be checked or not by default, using the following order:
By default, the checkbox is unchecked.
If get_site_option( 'auto_update_core_major' ) returns true, the checkbox is checked. Otherwise it’s unchecked. This option is the one stored in the database when the checkbox value is changed.
If WP_AUTO_UPDATE_CORE constant returns true, beta or rc, the checkbox is checked. If the constant returns false, minor or is not defined, the checkbox is unchecked. If this constant is set, it overrides the above parameters.
If allow_major_auto_core_updates filter returns true, the checkbox is checked. If the filter returns false or is not used, the checkbox is unchecked. If this filter is used, it overrides the above parameters.
To disable the checkbox by default, developers can set the WP_AUTO_UPDATE_CORE to false (to disable all auto-updates) or minor (to enable only minor core auto-updates, which is the default behavior). It has to be done using the wp-config.php file.
Developers can alternatively use the allow_major_auto_core_updates filter to set up core major versions auto-updates to true or false by default. Example:
How to extend core major versions auto-updates feature?
The feature also checks for dev (development versions of WordPress) and for minor updates. There is an action hook running right before the submit button of that settings section to add some options if needed. Using the after_core_auto_updates_settings_fields action hook, developers can add other settings or texts.
For example, the following snippet adds an option to opt-in/out for minor releases auto-updates:
