Update: The Drush 5 / 7 removal was planned for May 13 previously. This date has been updated to June 3, 2025.
As part of our ongoing platform maintenance and security improvements, Drush versions 5 and 7 will no longer be available on Pantheon starting June 3, 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.

Action Required
Sites using Drush 5 or 7 will need to upgrade to Drush 8 to maintain functionality and security:
- Test your site with a newer version of Drush (8 or newer)
- Update your site's Drush version
- Review your deployment workflows and CI/CD pipelines to ensure compatibility with the new Drush version
On June 3, 2025, all sites using Drush 5 or 7 will be auto-upgraded to Drush 8.
