Changeset 41254 for trunk/src/wp-admin/includes/misc.php

Timestamp:

Message:

Options, Meta APIs: Require a confirmation link in an email to be clicked when an admin attempts to change the site admin email address.

This adds this previously Multisite-only functionality to single site installations too. This change prevents accidental or erroneous email address changes from potentially locking users out of their site.
