Drush 5 and 7 no longer available starting May 13, 2025

April 8, 2025

As part of our ongoing platform maintenance and security improvements, Drush versions 5 and 7 will no longer be available on Pantheon starting May 13, 2025. After this date, sites using these versions will automatically be upgraded to Drush 8.

Drush 5 reached end-of-life (EOL) in May 2015 and Drush 7 in July 2017. EOL software does not receive security or feature updates, and could expose sites to attack if any vulnerabilities or exploits are discovered.

Find out which version of Drush your site is running.

Action Required

Sites using Drush 5 or 7 will need to upgrade to Drush 8 to maintain functionality and security:

  1. Test your site with a newer version of Drush (8 or newer)
  2. Update your site's Drush version
  3. Review your deployment workflows and CI/CD pipelines to ensure compatibility with the new Drush version

On May 13, 2025, all sites using Drush 5 or 7 will be auto-upgraded to Drush 8.
