Pantheon release notes

Terminus 4.1.6 is now available. This release adds the domain:verify command, new Elasticsearch search commands, and deprecates the legacy Solr commands.

Key improvements in this release

• Domain verification command: New domain:verify command allows users to verify domain ownership directly from Terminus (#2790)
• New search commands: New search:enable and search:disable commands for managing search indexing services (#2783, #2784)
  • Note: These commands are currently non-functional for WordPress until Elasticsearch platform compatibility is added
• Solr command deprecation: solr:enable and solr:disable are now deprecated in favor of the new search:enable and search:disable commands
• Bug fix: Fixed empty body handling to use object instead of array (#2780)

If you installed Terminus directly from the .phar file, you should upgrade using the self:update command:

We are continuing to enhance the Top Traffic Patterns interface to help you go from insight to action even faster.

• Click-to-Audit for top paths: You can now run Google Lighthouse performance audits directly from the Top Paths table. Easily check the performance and SEO scores of your most visited pages with a single click. (Note: To prevent errors, this option is automatically disabled for static assets and backend administrative paths).
• Streamlined IP Block Requests: Advanced Global CDN customers can now easily request blocks against bad actors directly from the dashboard. We've added an action link within the Top IPs table that automatically routes the malicious IP details to our support team for blocking, removing the friction of manual context switching.

Note: The Top Traffic Patterns feature is in active, iterative development. You can expect frequent updates and new enhancements in the near future.

The site list in the Pantheon dashboard now syncs your active filters and search terms to the URL. This means you can bookmark a filtered view, share it with teammates, or refresh the page without losing your place.

What's changed

• Shareable filtered views: Filter and search state is reflected in URL query parameters, so you can copy and share a link that opens the exact filtered view you're looking at.
• Persistent state on refresh: Filters and search terms are restored from the URL when you load the page, so a browser refresh no longer resets your site list view.

No action is required. The next time you visit your site list and apply filters, the URL will update automatically.

Pantheon is announcing a PHP version removal schedule. The following PHP versions will be removed from the platform on September 30, 2026:

• PHP 5.6
• PHP 7.0
• PHP 7.1
• PHP 7.2 (End of Sale: May 1, 2026)
• PHP 7.3 (End of Sale: May 1, 2026)
• PHP 8.0 (End of Sale: May 1, 2026)

PHP 5.6, 7.0, and 7.1 are already end-of-sale. PHP 7.2, 7.3, and 8.0 will reach end-of-sale on May 1, 2026, meaning no new sites can be created with these versions after that date.

Additionally, PHP 8.1 will reach end-of-sale on September 30, 2026, with a removal date to be announced at least 9 months in advance.

What happens when a PHP version is removed?

Sites still running a removed PHP version will be automatically upgraded to the oldest available PHP version at the time of removal. If your site's software has not been updated for compatibility, this may result in broken functionality.

What to expect going forward

Pantheon will guarantee at least 9 months of advance notice before removing any PHP version from the platform. Refer to the PHP version lifecycle table for the latest schedule.

Action required

If your site is running PHP 5.6, 7.0, 7.1, 7.2, 7.3, or 8.0, upgrade to a recommended PHP version before September 30, 2026 to avoid disruption. We recommend PHP 8.3 or 8.4 for all production sites.

For guidance on upgrading, refer to Upgrade PHP Versions.
