<h2>v9.0.0</h2>
<p><strong>New features:</strong></p>
<ul>
<li><strong><code>getOctokit</code> factory function</strong> — Available directly in the script context. Create additional authenticated Octokit clients with different tokens for multi-token workflows, GitHub App tokens, and cross-org access. See <a href="https://github.com/actions/github-script#creating-additional-clients-with-getoctokit">Creating additional clients with <code>getOctokit</code></a> for details and examples.</li>
<li><strong>Orchestration ID in user-agent</strong> — The <code>ACTIONS_ORCHESTRATION_ID</code> environment variable is automatically appended to the user-agent string for request tracing.</li>
</ul>
<p><strong>Breaking changes:</strong></p>
<ul>
<li><strong><code>require('@actions/github')</code> no longer works in scripts.</strong> The upgrade to <code>@actions/github</code> v9 (ESM-only) means <code>require('@actions/github')</code> will fail at runtime. If you previously used patterns like <code>const { getOctokit } = require('@actions/github')</code> to create secondary clients, use the new injected <code>getOctokit</code> function instead — it's available directly in the script context with no imports needed.</li>
<li><code>getOctokit</code> is now an injected function parameter. Scripts that declare <code>const getOctokit = ...</code> or <code>let getOctokit = ...</code> will get a <code>SyntaxError</code> because JavaScript does not allow <code>const</code>/<code>let</code> redeclaration of function parameters. Use the injected <code>getOctokit</code> directly, or use <code>var getOctokit = ...</code> if you need to redeclare it.</li>
<li>If your script accesses other <code>@actions/github</code> internals beyond the standard <code>github</code>/<code>octokit</code> client, you may need to update those references for v9 compatibility.</li>
</ul>
<h2>What's Changed</h2>
<ul>
<li>Add ACTIONS_ORCHESTRATION_ID to user-agent string by <a href="https://github.com/Copilot"><code>@​Copilot</code></a> in <a href="https://redirect.github.com/actions/github-script/pull/695">actions/github-script#695</a></li>
<li>ci: use deployment: false for integration test environments by <a href="https://github.com/salmanmkc"><code>@​salmanmkc</code></a> in <a href="https://redirect.github.com/actions/github-script/pull/712">actions/github-script#712</a></li>
<li>feat!: add getOctokit to script context, upgrade <code>@​actions/github</code> v9, <code>@​octokit/core</code> v7, and related packages by <a href="https://github.com/salmanmkc"><code>@​salmanmkc</code></a> in <a href="https://redirect.github.com/actions/github-script/pull/700">actions/github-script#700</a></li>
