Update post tags and authors without resending content

An API update that changed only a post's tags or authors could fail with a server error when the request omitted attributes. That error is fixed: valid relationship-only updates are now processed without requiring you to resend the title or body.

If your integration encountered this error, retry the relationship-only request using your existing API key and permitted tag or author IDs. Fields you do not send, including the title and body, stay unchanged. Existing API access and relationship-editing permissions still apply.

See the API reference for post updates and tag and author relationships.
