<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>When working with backporting months ago, I noticed that it's not always obvious if an MR was backported so I ended up checking ones that were tagged:</p>
<p><span class="drupalorg-gitlab-issue-link drupalorg-gitlab-link-wrapper"><a href="https://git.drupalcode.org/project/ai_initiative/-/work_items/3538642" class="drupalorg-gitlab-link">https://git.drupalcode.org/project/ai_initiative/-/work_items/3538642</a></span></p>
<p>And found some that weren't actually backported, even though they were tagged for it.</p>
<p>I suggested that checking this be added as a release process step and Marcus said he can create a script for it.</p>
<h4 id="summary-steps-reproduce">Steps to reproduce (required for bugs, but not feature requests)</h4>
<p>Please provide information like AI modules enabled, which AI provider, browser, etc.</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Create a script and update the release process to include:</p>
<ul>
<li>Check each issue in the release that is tagged for backporting</li>
<li>Check the relevant branches to make sure it was actually backported</li>
<li>Also check newer branches when the issue is set for an older branch to make sure it's included</li>
<li>If it <strong>WAS</strong> backported, <strong>REMOVE</strong> the tag from the issue</li>
<li>If it <strong>WAS NOT</strong> backported, <strong>BACKPORT</strong> it and then <strong>REMOVE</strong> the tag from the issue</li>
</ul>
<p>Tags:</p>
<ul>
<li>needs backport to 1.1.x</li>
<li>needs backport to 1.2.x</li>
<li>needs backport to 1.3.x</li>
</ul>
<h3 id="summary-remaining-tasks">Remaining tasks</h3>
<ul>
<li>Create script</li>
<li>Test and review script</li>
<li>Update release process docs</li>
<li>Review process changes</li>
</ul>
