Co-Authors Plus 4.1.0

Added

• Add an --append_coauthors flag to the wp co-authors-plus assign-user-to-coauthor WP-CLI command, allowing the new co-author to be appended rather than skipping any post that already has co-authors assigned by @RobjS and @GaryJones in #1264 and #1267
• Accept --user_id as an alternative to --user_login on wp co-authors-plus assign-user-to-coauthor, so posts whose post_author references a user that no longer exists (orphaned posts) can be reassigned to a co-author by @GaryJones in #1266
• Add --offset and --number parameters to the wp co-authors-plus create-guest-authors WP-CLI command, so guest-author creation can be run in resumable chunks across large user bases by @aaronjorbin in #378
• Add a column to the Users list table showing each user's linked guest author, clarifying why a linked account's post count differs by @jeherve in #502
• Add contextual Screen Help tabs to the Guest Author admin screens, explaining linked accounts, slugs, the Posts column, and the delete reassignment options by @GaryJones in #1272
• Honour Yoast SEO's author-archive indexing setting (noindex-author-wpseo), so toggling "Show author archives in search results" off is respected on co-author archive pages by @mchanDev in #1062
• Add a coauthors_plus_is_author_query filter so a specific WP_Query can opt out of the co-author taxonomy rewrite and run as a standard post_author query by @faisalahammad in #1304

Changed

• Memoise supported_post_types() so the supported-post-type list is computed once per request rather than rebuilt on each of its many calls by @douglas-johnson and @GaryJones in #1307

Fixed

• Honour the Archive Title block's showPrefix toggle on author archive pages so the "Author:" prefix can be hidden in block themes by @GaryJones in #1259
• Restrict the guest-author "Linked Account" dropdown to users with the edit_posts capability, preventing the dropdown from rendering hundreds of thousands of subscribers and crashing the browser on large sites by @leogermani in #941
• Guard get_current_screen() calls to prevent a fatal error when admin code runs in early-init contexts where the current screen has not yet been set by @faisalahammad in #1260
• Sync post_author to the assigned co-author on REST save before wp_insert_post fires, so the value Jetpack Sync ships is correct on the first save and the newsletter preview no longer shows the post creator until a second save by @GaryJones in #1273
• Keep post_author pointing at the first co-author after reordering co-authors in the block editor, so the_author(), the REST author field, and author archives reflect the new order by @GaryJones in #1298
• Normalise the block editor's co-author entity-store values to term IDs, fixing the empty /authors-by-term-ids responses and permanent sidebar spinner that appeared where the store returned full author objects by @faisalahammad in #1283
• Keep the block editor's "Select An Author" combobox populated with the alphabetical author list before a search is typed, so it no longer shows "No items found" on focus or after clearing the query by @faisalahammad in #1305
• Preserve feed query flags when clearing conflicting flags on guest-author pages, so author feed URLs like /author/USERNAME/feed/ are served as feeds rather than the HTML archive by @faisalahammad in #1303
• Render the posts list table's Authors column from the row's post ID rather than the global $post, fixing a warning and blank column when the list is built from a programmatic WP_Query (for example Admin Columns exports) by @justinmaurerdotdev and @GaryJones in #1309
• Refresh a co-author's search term and clear its cached author term when the linked user's profile changes, so author search stays current on sites with a persistent object cache by @GaryJones in #1312
• Guard against get_post_type_object() returning null when the coauthors_supported_post_types filter restricts the plugin to a single custom post type, avoiding PHP warnings by @garubi in #1114
• Guard against a missing post or ID in Yoast's filter_graph context, preventing PHP warnings when a post type is excluded from the Yoast index by @mattwatsoncodes in #1125

Maintenance

• Move hook registration out of the plugin's class constructors, so instantiating CoAuthors_Plus, CoAuthors_Guest_Authors, the REST endpoints, and the template filters no longer mutates the global hook registry as a side effect by @GaryJones in #1316
• Resolve Plugin Check (PCP) violations across the codebase: add ABSPATH direct-access guards, escape _deprecated_hook() message strings, add translator comments for block sprintf() calls, migrate get_terms() to the single-array signature, and harden input sanitisation by @faisalahammad in #1284, #1285, #1286, #1287, #1288 and #1289
• Restructure the PHP test suite into feature-focused files and sub-directories, and add a WordPress-free unit test layer by @GaryJones in #1317 and #1319
• Fix and enforce the JS and CSS lint baseline so ESLint and Stylelint can fail CI again by @GaryJones in #1318
• Update development dependencies by @dependabot

Documentation

• Add missing PHPDocs to four legacy template-tag and upgrade functions by @GaryJones in #1265
