Telegram’s Bot API 9.1 introduces major updates for developers, highlighted by new checklist functionality. Business bots can now create and edit interactive checklists using dedicated classes (Checklist, ChecklistTask) and methods (sendChecklist, editMessageChecklist), enabling task tracking directly in messages.

Additional upgrades include enhanced gift management with resale tracking fields (next_transfer_date, last_resale_star_count), expanded surveys (now 12 options), and bot monetization tools like star balance checks (getMyStarBalance). Web App controls now feature a hideKeyboard method.

These updates emphasize Telegram’s push toward multifunctional business tools, though broader user utility remains in development.
