v1.2.1

Fixed

• WP-2724 - Cast WP_Post::$post_author to int in User\Watcher to prevent TypeError on post_updated and save_post.

v1.2.0

What's Changed

• WP-2681 - Prevent warning and TypeError when a sitemap item references a missing user
• Disable WPSEO_Sitemaps_Admin hooks when replacing Yoast sitemaps. Its transition_post_status handler invalidates the WordPress lastpostmodified object cache on every post publish, causing expensive ORDER BY post_modified_gmt DESC full table scans on high-volume sites.
