Pantheon Release Notes

Terminus 4.0.0 release now available

Tools & APIs
May 8, 2025

Terminus 4.0.0 is now available. This release:

  1. adds support for PHP 8.4,
  2. removes support for PHP versions 8.1 and below,
  3. improves interactive mode by prompting users for any missing required command parameters.

Terminus 4 is compatible with PHP 8.2 and 8.3 (see Supported Terminus and PHP versions). The PHP version refers to the local machine on which Terminus itself runs (e.g. developers' own computers or containers for continuous integration). This is distinct from PHP versions that run websites on Pantheon's infrastructure, which still include support for PHP 7.x.

For more information about this release, visit the GitHub release page.

How to upgrade to Terminus 4.x

If you use Homebrew (macOS-only) to manage your Terminus installation, you should upgrade using:

brew upgrade terminus

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

terminus self:update

You can find more details about Terminus 4 in our documentation.
