Sometimes newer isn’t always better.
You won’t always want to update a given plugin. Perhaps the design has been changed, or a bug has been introduced. Maybe it has been taken over by someone new and they’ve added loads of obnoxious ads or other sneaky monetisation methods. Or perhaps you just like it the way it is.
However, WP keeps telling you there’s a new version available, and lists it along with other plugins which you may actually want to update.
What happens if you accidentally update? At best, it’s a tedious downgrade process, at worst it may completely mess up the data that the plugin was using. In any case, it’s a pain and there’s no ignore update function in WP.
Until now!
IMPORTANT – You should only leave a plugin updated if you know what you are doing, familiar with the risks and willing to accept the consequences should an unpatched vulnerability be exploited on your site.
The plugin author cannot be held responsible for any loss or damages that occur as a result of using this plugin to disregard software updates!

Disables the default notification emails sent by a site after an automatic theme and/or plugin update. Simply activate the plugin to disable these email notifications (allows failure notices through unless setting is enabled to disable these as well).
This is a simple & lightweight plugin that simply uses the official filters made available as of WordPress 5.5 to disable these email notifications upon activation. It does let update failure notifications through by default, but the Settings => General page has a setting to disable these as well.
