  1. Related Posts for WordPress 3.0.1Latest

    • Security: Fixed an exposure of post titles that could be abused by users with the Contributor role or higher: linking a draft, pending, scheduled, private or trashed post of another user to a post of their own showed its title in the Related Posts meta box. The screen to add related posts now only…
    • Security: The All Posts view of the screen to add related posts no longer lists the private posts of other users, with their titles and dates, to users who can’t read them. It also leaves posts the user can’t read out of its count and its search, including on sites that offer drafts or other status…
    • Tweak: The readme says more precisely what the update to 3.0 does, which posts get better related posts and which filters were removed.
    • Fix: The Rebuild everything card and its confirmation on the Installer tab say that links you added by hand stay, as they do, instead of that they are removed. Translated in all 19 bundled languages.
    • Tweak: The documentation links on the settings screen and in the readme go to the new documentation site, docs.relatedpostsforwp.com.
    • Fix: Next to Premium 2.x, the notice that asks to update Premium no longer links to the Plugins screen when WordPress has no update for Premium, which only reloaded the page. Premium 2.x only offers its update while its license is activated, so the notice now asks to download Premium 3.0 from your…

    • Feature: A new settings screen, with the installer built in. The installer runs in the background, so the page can be closed while it works, and the screen shows its progress.
    • Feature: The settings screen has a sidebar again, with links to the documentation and the support forum, and what Premium adds.
    • Feature: Link the posts that are not linked yet, or rebuild every link, from the new Installer tab. Rebuilding asks first, and keeps the related posts you added by hand (2.x removed them).
    • Feature: A modern default layout for the related posts, built with flexbox instead of floats. It works for right-to-left languages without a separate stylesheet, and themes can change the spacing and the image width with the CSS custom properties –rp4wp-gap and –rp4wp-image-width. Sites that change…
    • Feature: Related posts shown by the shortcode or the widget outside single posts, on pages and archives for example, get the CSS too.
    • Feature: The rp4wp_disable_css filter turns the CSS off, as in Premium.
    • Feature: Related Posts for WordPress Premium 3.0 is an add-on for this plugin: keep both installed and active. Next to Premium 2.x, this plugin leaves the related posts to Premium and asks to update it.
    • Feature: Better related posts. The words of a post count by how often they are in it and how rare they are on your site, and posts are compared as a whole, so words that are in every post decide little and long posts no longer lose out to short ones. Every post keeps its 25 most telling words (it w…
    • Feature: Categories, tags and the posts a post links to count when finding related posts: the words of their names, and the category, tag or linked post itself. A category with most posts in it counts for little.
    • Feature: The ignored words follow the language of each post, from WPML or Polylang or from the words of the post, with the ignored words of 57 languages. Chinese and Japanese, written without spaces, are split into words, so their posts get much better related posts, and more accented letters match…
    • Feature: After the update, every post is read again in the background, and the posts that were linked automatically are linked again, one post at a time. Each post keeps its related posts until its new ones are in place, related posts you added by hand keep their place and count toward the number o…
    • Tweak: A word of the title counts 5 times (it was 80), a tag 5 (10) and a category 10 (20), so the content of a post counts too.
    • Tweak: A post published while the installer or the update runs is linked when it is done, with the words of every post in place.
    • Tweak: The links and the marks on posts move from posts and post meta to tables of their own, which makes showing related posts faster. The update moves them, and wp rp4wp migrate shows and undoes the changes to the database.
    • Tweak: The filters rp4wp_get_children_link_args and rp4wp_get_parents_link_args are removed; rp4wp_links_query takes their place. The new filter rp4wp_finder_clauses changes the query that finds related posts.
    • Tweak: Related posts you add by hand are marked as such, so the refresh of Premium keeps them, also on a site that gets Premium later.
    • Fix: The words of a post are removed when it is deleted or unpublished, also from WP-CLI and cron.
    • Fix: Words with 4-byte letters are stored, and HTML entities no longer count as words.
    • Fix: The rp4wp_after_link_add and rp4wp_after_link_delete actions fire for every link, also when posts are linked in batches or a post is removed.
    • Fix: Related posts with the same link order keep the order they were added in, so a limit or an offset in the shortcode always shows the same posts.
    • Fix: The related posts meta box skips links to posts that no longer exist.
    • Fix: The installer no longer keeps waiting on posts without words or with emoji.
    • Fix: PHP 8 deprecation notices, and word extraction no longer changes the locale of the rest of the request.
    • Fix: Deleting the plugin with “Remove data on uninstall” on also removes the widget settings, the state of an unfinished installation wizard, the dismissed review notice and the chosen number of links per page.
    • Tweak: Titles, settings and links in the admin are escaped.
    • Tweak: The notices about mbstring and the unfinished installation wizard can be translated.
    • Tweak: The bundled Dutch, French, German, Italian, Portuguese (Brazil and Portugal), Serbian, Swedish and Ukrainian translations are updated for 3.0, the new settings screen included.
    • Tweak: The translations that come with the plugin are used first, so they are complete for this version; a language pack from translate.wordpress.org only adds strings they lack.
    • Feature: New translations in Bulgarian, Czech, Dutch (formal), German (formal), Japanese, Norwegian (Bokmål), Polish, Russian, Spanish (Spain) and Turkish.
    • Tweak: The Settings link on the Plugins screen also shows when the plugin folder is renamed.

  3. Related Posts for WordPress 2.3.1

    • Security: Fixed an SQL injection in bulk linking that could be abused by users with the Contributor role or higher.
    • Security: Users can now only add, remove or reorder related posts on posts they are allowed to edit.
