What's new
The action_list widget. An answer's options now render as tappable rows — tap one and the SDK sends it as your next turn instead of making you retype it.
Upgrading
Update your SPM dependency to 2.1.0. No code changes required.
Consumers on 2.0.x are unaffected: an unknown widget kind decodes to .unknown and is dropped, so the engine can emit action_list to every client without gating on SDK version. You only see the new widget once you upgrade.
