<summary>actions/github-script (actions/github-script)</summary>

### [`v9.0.0`](https://redirect.github.com/actions/github-script/releases/tag/v9.0.0)

[Compare Source](https://redirect.github.com/actions/github-script/compare/v9.0.0...v9.0.0)

**New features:**

- **`getOctokit` factory function** — 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 [Creating additional clients with `getOctokit`](https://redirect.github.com/actions/github-script#creating-additional-clients-with-getoctokit) for details and examples.
- **Orchestration ID in user-agent** — The `ACTIONS_ORCHESTRATION_ID` environment variable is automatically appended to the user-agent string for request tracing.

**Breaking changes:**

- **`require('@&#8203;actions/github')` no longer works in scripts.** The upgrade to `@actions/github` v9 (ESM-only) means `require('@&#8203;actions/github')` will fail at runtime. If you previously used patterns like `const { getOctokit } = require('@&#8203;actions/github')` to create secondary clients, use the new injected `getOctokit` function instead — it's available directly in the script context with no imports needed.
- `getOctokit` is now an injected function parameter. Scripts that declare `const getOctokit = ...` or `let getOctokit = ...` will get a `SyntaxError` because JavaScript does not allow `const`/`let` redeclaration of function parameters. Use the injected `getOctokit` directly, or use `var getOctokit = ...` if you need to redeclare it.
- If your script accesses other `@actions/github` internals beyond the standard `github`/`octokit` client, you may need to update those references for v9 compatibility.
