Bot API 10.4

📚 Widget Revolution
HTML widgets bring custom, dynamic interfaces right into message bubbles – giving bots and AI agents a new canvas for interactive tools, games and workflows.

• Bots can now send native HTML widgets with dynamic layouts, custom sizing, interactive elements and more.
• Widgets can send queries and receive answers, letting users interact freely with a reactive UI.
• Bots can update widgets in place, keeping dynamic UIs up to date.
• Shared widgets also let bots reuse the same UI across messages – updating it instantly from a centralized setting.

🏳 TON Wallet
• Widgets seamlessly integrate with Telegram's native Wallet – with support for signing or notifying user transactions to bots.
• Bots can also read users' wallet cards, including balances and NFT stickers, and detect service messages about wallet transfers.

👻 Ephemeral Messages
• Button presses can now trigger ephemeral replies visible only to the user who tapped – unlocking custom reactive flows in shared chats.

✈ General
• Bots can now easily quote rich messages.
• Bots can now look up unique gifts by name, simplifying gift integration.
• Premium users can now give up to two of their bots secondary usernames ending in agent, ai, app, game or gay.
