Changeset 33083 for trunk/src/wp-includes/ms-functions.php

Timestamp:

Message:

Usernames in multisite should be restricted to 60 characters or fewer.

Only 60 characters can be stored in the database for a username, which could cause lookup issues when attempting to use similar usernames of extreme length.

Props @DJPaul.
See #17904, Fixes #26784.
