What to upgrade to
Go to 2.10, not 2.2.
2.2 runs out in 63 days. 2.10 is the newest supported Composer cycle.
Before you upgrade
composer self-update moves to the newest release. 2.2 is a long-term release for PHP older than 7.2; don’t pin it on a modern server. Read the Composer 2.10 upgrade guide
How to check your version
Which Composer is this site on?
On the server
Know before support ends.
Porro reads the PHP, framework and database version from every site and tells you 90 days before support runs out.
