Getting too many "plugin updated" or "theme updated" emails since WordPress 5.5? This turns them off.
There’s not much to this plugin. It’s a couple barebones filters that turn off the plugin and theme autoupdate emails.
On WordPress 5.5.0, plugin/theme autoupdate emails are turned off regardless of whether or not they failed.
Since WordPress 5.5.1, emails indicating update failures are allowed through.
