This unofficial plugin provides fixes for selected WordPress bugs, so you don’t have to wait for the next WordPress core release. This does not mean you can stop updating WordPress! It just means that you’ll get a few selected fixes more quickly.
Recent fixes:
<ul>
<li>WordPress 6.9
<ul>
<li>Set sender as blank to workaround Sendmail issue when sendmail_from and -f are both used, see <a href="https://core.trac.wordpress.org/ticket/64368" rel="nofollow ugc">WP#64368</a>.</li>
</ul>
</li>
</ul>
Fixes are specific to your version of WordPress. It may be that your version of WordPress has no fixes. That’s fine. Keep the plugin activated and updated, in case you need it for a subsequent version of WordPress!
