##### Requirements
* Increased the minimum required PHP version to 5.6. Technically, some AME features may still work on older PHP versions, but those versions are now officially unsupported.
#### Added
* Added a way to delete meta box settings associated with post types and taxonomies that no longer exist.
##### Fixed
* Fixed a number of deprecation warnings related to PHP 8.
* Fixed a conflict with "Anti-Spam by CleanTalk" that could potentially cause a fatal error.
* Fixed a conflict with "Admin Theme - Musik" where the menu order settings in the other plugin would override the menu order configured in AME.
* Fixed a subtle conflict with plugins that use the boolean value TRUE as a capability name. For example, "Admin Columns Pro - WooCommerce" version 3.7.3 caused the "manage_woocommerce" capability to disappear.
* Fixed missing padding in the "edit plugin details" panel (in the "Plugins" tab). Also updated the button layout to match the new button layout of the "Quick Edit" panel introduced in WP 6.0.
* Fixed a visual issue where some form fields might briefly show up and then disappear if the settings page stylesheet took a while to load.
##### Changed
* Removed dependency on the "icon16" CSS class. The class is likely to be removed in WP 6.1.
