Changeset 33058 for trunk/src/wp-admin/includes/upgrade.php

Timestamp:

07/03/2015 05:43:28 AM (7 years ago)

Author:

Message:

Don't upgrade global tables to utf8mb4 when wp_should_upgrade_global_tables() says not to.
Additionally fixes an incorrect conditional in [33057] which would result in the usermeta index being altered twice on Multisite updates.

See #32154
