This is is a feature and maintenance release, with an important bug fix. As always compatible with Joomla 3 to 6 without compatibility plugin.
Here are the highlights:
Refreshed user interface, less distraction and more compact
Generation of Markdown alternate version of your pages automatically. Supports Content Signals policy to tell bots what they can do with your content. Also: content negotiation, canonical/alternate link management, structured data, configurable caching. Particularly useful for software or product documentation for instance
Support for llms.txt file generation. Not used for SEO/AEO/GEO but can be useful for product or software documentation pages
Added support for Content Signals policy. Tell bots which use of your content you allow.
Added option to decide if automatic change detection runs on entire page or on just main content. Use the latter if your pages have modules with random or often updated content, causing 4SEO to re-analyze pages too often
Joomla light/dark mode switch in User menu now also control our light/dark mode
Prevent Joomla using null as an array offset on 404s, which causes PHP deprecation warnings
YooTheme Pro template can now display 4SEO error pages in full - Joomla 5+ only
Sitemaps are now served without cookies
Prefer the live meta description possibly set by Joomla, if any, over the one stored during analysis, in case the page has not been re-analyzed yet
Under rare circumstances, Joomla may redirect some 404s to home page, when a 4SEO error page is active
Redesigned notifications icon, was not accessible
Some toolbar buttons may fail WCAG 2.2 AAA in light mode
Changed striped tables dark rows background color, was not WCAG 2.2 AAA compliant
FAQPage and ListItem structured data types use wrong letter case
Dutch language shows HTML tags in initial setup wizard title
Some expansion variables may not be available (published date)
chg FAQ structured data is no longer a page-level entity, can now be added to other page types such as Article or Product
chg Added forseo_sd_cache_id filter. May help in cases where Joomla progressive/conservative caching prevents custom fields values to be used in structured data rules
chg Automatic description: now prefers component content over custom fields content. Added new filter to toggle that choice (forseo_auto_desc_prefer_components_content)
chg More efficient background images dimensions retrieval
chg Now stripping HTML tags from Hikashop product name when generating structured data records
chg When generating and structured data records, now using the configured instead of that coming from Joomla, for better consistency
chg Redesigned dashboard alerts, less overwhelming and more informative
chg Do not suggest to use an analytics solution if 4Analytics is installed
bug Under some rare circumstances, a PHP warning showing about using foreach() on null can be visible on page (if server is configured to display errors). No consequence on operations.
bug Some redirects rules may not work
bug Possible PHP warning on Structured data Event rule, if Location Name is a custom field, but no value has been set in the item for it
new Unpublishing existing articles now triggers an immediate update of the sitemap. These items are also not suggested anymore in the [Similar pages] section of error pages. Publishing back the articles also causes the sitemap to be updated accordingly. Unpublished articles now have an [Error] Status on the Pages page
chg PHP 8.4 and 8.5 compatibility improvements
chg Now removing content of alt attributes in content before trying to automatically build a meta description
chg New option in metadata rule to suppress the meta description from pages. Search results snippets are usually created automatically by search engines, and having no meta description may result in better click rates according to recent studies
chg New option in metadata rule to always use the configured default sharing image instead of the automatically selected one
chg Added 3rd option to Core Web Vitals filter: [With Data]. This hides pages that have no Core Web Vitals measurements yet, allowing comparison between passing and failing pages
chg (small) performance improvement by not adding hooks on some events in the backend, while they are only useful on the frontend
bug On dark theme systems, standard text of first install configuration wizard is hardly visible
bug Possible PHP warning in logs in case of error connecting to the Google Search Console
bug Possible error on some combinations of SPPageBuilder and Joomla versions. Does not affect live site
bug J6 does not implement Table classes for contact and newsfeeds, only content, can cause fatal errors when some rules use contact or newsfeeds category specification
