Bot API 10.0

Today's update reshapes how bots communicate on Telegram – unlocking cooperative multi-bot agentic flows, seamless integration in any chat, granular access controls and more.

🦀 Guest Mode and Agentic Flows
• Introduced guest mode, allowing bots to easily participate in any chat without joining it.

• Account automation via Business Bots no longer requires a Premium subscription.
• Business Bots can now interact with other bots on behalf of the user.

• The list of chat admins can now optionally return bot administrators.

🚶 Live Photos
• Introduced support for live photos – images enhanced with short built-in motion and sound.
• Bots can now detect, download and send live photos to any chat, including as paid media.

📊 Polls
• Bots can now detect and attach media in both polls and individual poll options.
• Polls can now be limited to existing chat members or voters from specific countries.

✈ General
• Users can now set a granular access whitelist for their bot via @BotFather, while Manager Bots can set one via the API.
• Bots can now fetch recent messages from the channel pinned to a user's profile.
