Updating Our Platform to Use Composer 2.x by Default

Incident Report for Server Status | Nexcess

Investigating

On July 23rd, we will update our platform to use Composer 2.x by default. Composer 1.x will remain available as the composer1 command for backward compatibility, where possible.

Important Reminder:

Starting September 1, 2025, Composer 1.x will lose access to metadata from Packagist.org. This change impacts platforms that use Composer 1. x.

Using composer install or composer update with Composer 1.x and Packagist will fail after this date. Live sites will not be affected unless updates or dependency changes are performed.
