Changeset 30494 for trunk/src/wp-includes/taxonomy.php

Timestamp:

Message:

Improve cleanup of cached term_ids after shared terms are split.

• If the split term ID is stored as 'default_category', 'default_link_category', or 'default_email_category', update it to the new ID.
• If the split term ID is associated with a nav menu item, update that piece of postmeta to the new ID.

Props mboynes.
See #30335.
