⚠️ WARNING! ⚠️ After the next Bot API update (Bot API 5.3) there will be a one-time change of the value of the field FileUniqueId in objects of the type PhotoSize and of the fields SmallFileUniqueId and BigFileUniqueId in objects of the type ChatPhoto.

⚠️ WARNING! ⚠️ Service messages about non-bot users joining the chat will be soon removed from large groups. We recommend using the “chat_member” update as a replacement.

⚠️ WARNING! ⚠️ After one of the upcoming Bot API updates, user identifiers will become bigger than 2^31 - 1 and it will be no longer possible to store them in a signed 32-bit integer type. User identifiers will have up to 52 significant bits, so a 64-bit integer or double-precision float type would still be safe for storing them. Please make sure that your code can correctly handle such user identifiers.
