Yoast SEO 1.5.4

  • Fixed: %%pt_single%% and %%pt_plural%% didn't work in preview mode.
  • Fixed: %%page_total%% would sometimes be one short.
  • Fixed: %%term404%% would sometimes be empty while the pagename causing the 404 was known.
  • Fixed: empty taxonomy sitemap could still be shown, while it shouldn't, as reported by allasai in issue #1004 - props Jrf.
  • Fixed: if first result of a search is a post, the blog page was incorrectly added to the breadcrumb, as reported in issue #1248 by Nikoya - props Jrf.

  • saving of settings on the multisite settings page was not working.
  • restoring site to default settings from multisite settings page was not working.
  • initializing new blogs with settings from a chosen default blog was not working (might still not be completely stable for WP multisite with WPSEO in must-use plugins directory, stable in all other cases).
  • wrong option debug information shown on multisite settings page
  • Fixed: an issue with sitemap transient caching for plugins not using paginated sitemaps (like news seo).
  • Check if get_queried_object_id is not 0 before enqueueing wp_enqueue_media.
  • Set rssafter to empty string on test_embed_rss() test.

  • Heavily reduce query load for XML sitemaps by caching XML sitemaps in transients.
  • New wpseo_register_extra_replacements action hook which lets plugin/theme builders add new %%...%% replacement variables - including relevant help texts -. See function documentation for an example of how to use this new functionality.
  • If the final string - after replacement - would contain two separators with nothing between them, this extra separator will be removed.
  • All remaining not replaced replacement vars are now stripped from the strings (without breaking the snippet preview).
  • New filter wpseo_replacements_filter_sep which can be used to change the seperator character passed by the theme.
  • When using the 'Reset default settings' button on a blog in a network while another blog has been chosen to be used as a basis for the settings for all new blogs, the reset will respect that setting and reset the blog to the settings from the chosen blog.
  • For small networks ( < 100 sites ), the network page user interface has been improved, by offering drop-down lists of the blogs for blog selection fields. For larger networks, the interface remains the same.
  • Added an action to allow adding content to the Post Type tab on the meta admin page.
  • Removing the extra blog name added to the title by woo_title().
  • More optimization improvements to snippet preview.
  • Add filter to allow other plugins to interact with our metaboxes outside of the standard pages - props Jrf.
  • Replace variables through an AJAX call, which makes them work in the post editor too and allows for more variables to be replaced in the title.
  • Added priority filters for XML sitemaps.
  • Other enhancements
  • Security improvement: As the .htaccess / robots.txt files are site-wide files, on a multi-site WP installation they will no longer be available for editing to individual site owners. For super-admins, the 'SEO -> Edit Files' admin page will now be accessible through the Network Admin.
  • We've added server specific info to our tracking class. Most notably, we're tracking whether a number of PHP extensions are enabled for our users now.
