Co-Authors Plus 4.2.2Latest
- Changed: Guest authors without a linked user no longer receive comment moderation emails, and Contributors no longer receive them for published posts.
- Security: Co-authors only receive comment emails for posts and comments they can access.
- Security: Tighten how guest author profiles are looked up, who can see co-authors’ email addresses, how private posts are counted, and who can change a post’s author.
Co-Authors Plus 4.2.1
- Changed: wp co-authors-plus export-coauthors now requires --file. If you ran it without --file on 4.2.0, delete wp-content/cap-coauthors-export.json.
- Changed: A Query Loop containing Co-Authors Plus blocks no longer forces “Reload full page”.
- Fixed: Author archive URLs for a slug that matches no one return a 404, instead of listing posts.
- Fixed: The Authors panel and blocks load in the block editor on WordPress 6.4 and 6.5.
- Fixed: Post counts and author lists treat a linked user and guest author as one person, so posts aren’t counted twice and guest authors don’t go missing from lists.
- Fixed: Authors whose nicename isn’t a clean slug, as some SSO and sync plugins write them, appear in the author search and in bylines.
- Fixed: Yoast SEO’s structured data stays valid on posts with co-authors.
- Fixed: wp co-authors-plus create-guest-authors accepts --role and other user query arguments again.
- Security: Tighten how co-authors and author queries are matched.
Co-Authors Plus 4.2.0
- Changed: RSS feeds credit each item’s co-authors on every site. To keep the old feed bylines, return false from the coauthors_filter_feed_authors filter.
- Changed: Creating, listing and editing guest authors needs the guest author manage capability (Administrators by default) everywhere, including WordPress’s own post screens, so Editors can no longer edit guest authors there. Change this with the coauthors_guest_author_manage_cap filter.
- Changed: Setting co-authors on pages and custom post types checks that post type’s own edit-others capability.
- Changed: Core’s /wp/v2/coauthors REST route needs the edit_posts capability, and /wp/v2/guest-author is gone. Read co-authors through the plugin’s coauthors/v1 endpoints, which now return unescaped values.
- Changed: The plain byline template tags, such as coauthors(), escape their output.
- New: WP-CLI commands to move guest authors and their bylines between sites (export-coauthors, import-coauthors) and to list a post’s co-authors (list-authors).
- New: Filters to change the author data in the editors’ author search, for example to hide email addresses.
- Fixed: Co-author names with apostrophes display correctly in the block editor, and the Authors panel fills in on sites that override the coauthors REST field.
- Fixed: Trashing a guest author no longer drops them from bylines.
- Fixed: Many WP-CLI commands now do what they report, including swap-coauthors --dry-run, reassign-terms and the author term backfills.
- Security: Tighter permission checks for managing guest authors, and no more user logins in public REST responses.
