<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>All testing on previous major is currently breaking because the code for doctrine/instantiator 2.1.0 required PHP 8.3. Because the composer install doesn't check for versioning.</p>
<p>We need to make sure that previous major that is on PHP 8.1, uses 2.0.0 of the version.</p>
<p>This is a pure testing issue, so it won't affect the module as it is.</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>On previous major downgrade use composer on phpunit to downgrade to 2.0.0</p>
