Disable Theme and Plugin Auto-Update Emails

This plugin stops the flood of email notifications sent after automatic theme and plugin updates. It is designed for site administrators who manage multiple sites and want to reduce inbox noise without disabling automatic updates themselves.

• Simple activation: No configuration is needed to block successful update emails. Just activate the plugin, and the notifications stop immediately.
• Optional failure notice control: By default, emails about failed updates are still sent. A checkbox on the Settings > General page lets you disable those as well, giving you full control over what you receive.
• Lightweight and efficient: The plugin uses the official filters introduced in version 5.5. It adds no overhead to your site and does not alter any update behavior.
• Easy to reverse: Deactivating the plugin restores the default email behavior. There is no complex settings screen to manage.
• Compatible with other notification plugins: Works alongside plugins that handle core update notifications, so you can choose exactly which emails to block.
