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. • And more, see the full changelog for details: https://core.telegram.org/bots/api-changelog#june-20-2022 Warning: Only HTTPS links are now allowed in login_url.
