Bot API 6.1

Telegram Premium
• To support 4GB files uploaded by premium accounts, file_size in most media classes can no longer be stored in a signed 32-bit integer type.
• Bots can now distinguish premium Users and Stickers with the new respective fields is_premium and premium_animation.

Web Apps
• Added several methods and fields to the class WebApp to handle API version, additional colors, haptic feedback and more.
• Added the events backButtonClicked, settingsButtonClicked and invoiceClosed.
• Updated ThemeParams, MainButton and WebAppInitData with new fields and methods.

Groups, Payments and Attachment Menu
• Bots can now process join requests created without an invite link – they will still receive a chat_join_request update.
• HTTP links for invoices can be generated with the new createInvoiceLink method.
• Bots can now detect when a user added them to their attachment menu via the new added_to_attachment_menu field. Integrated bots can now also be used in groups, supergroups and channels.

• Check that your bot's webhook was set by you with the new secret_token parameter.
