December 30, 2021
+Bot API 5.6
+-
+
- Improved support for Protected Content. +
- Added the parameter protect_content to the methods sendMessage, sendPhoto, sendVideo, sendAnimation, sendAudio, sendDocument, sendSticker, sendVideoNote, sendVoice, sendLocation, sendVenue, sendContact, sendPoll, sendDice, sendInvoice, sendGame, sendMediaGroup, copyMessage, forwardMessage to allow sending messages with protected content to any chat. +
- Added support for spoiler entities, which will work in Telegram versions released after December 30, 2021. Older clients will display unsupported message. +
- Added new MessageEntity type “spoiler”. +
- Added the ability to specify spoiler entities using HTML and MarkdownV2 formatting options. +
December 7, 2021
+Bot API 5.5
+-
+
- Bots are now allowed to contact users who sent a join request to a chat where the bot is an administrator with the can_invite_users administrator right – even if the user never interacted with the bot before. +
- Added support for mentioning users by their ID in inline keyboards. This will only work in Telegram versions released after December 7, 2021. Older clients will display unsupported message. +
- Added the methods banChatSenderChat and unbanChatSenderChat for banning and unbanning channel chats in supergroups and channels. +

- Added the field has_protected_content to the classes Chat and Message. +
- Added the field is_automatic_forward to the class Message. +
Note: After this update it will become impossible to forward messages from some chats. Use the fields has_protected_content in the classes Message and Chat to check this.
+Note: After this update users are able to send messages on behalf of channels they own. Bots are expected to use the field sender_chat in the class Message to correctly support such messages.
+Note: As previously announced, user identifiers can now have up to 52 significant bits and require a 64-bit integer or double-precision float type to be stored safely.
+November 5, 2021

+-
+

creates_join_requestto the methods createChatInviteLink and editChatInviteLink for managing chat invite links that create join requests (read more about this on our blog).

WARNING!
User identifiers will become bigger than2^31 - 1before the end of this year 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.

NEW Multilingual Bots
+-
+
- The User object now may have a language_code field that contains the IETF language tag of the user's language. +

More power to admin bots
+-
+
- unbanChatMemeber now also works in channels! +
- New method deleteMessage that allows the bot to delete its own messages, as well as messages posted by other in groups and channels where the bot is an administrator. +
Minor Changes
+-
+
- Replaced the field new_chat_member in Message with new_chat_members (the old field will still be available for a while for compatibility purposes). +

December 4, 2016
+Introducing Bot API 2.3.1, a nifty little update that will give you more control over how your bot gets its updates.
+-
+
- Use the new field max_connections in setWebhook to optimize your bot's server load +
- Use allowed_updates in setWebhook and getUpdates to selectively subscribe to updates of a certain type. Among other things, this allows you to stop getting updates about new posts in channels where your bot is an admin. +
- deleteWebhook moved out of setWebhook to get a whole separate method for itself. +

+Bot API 2.3
+-
+
- Modified bot privacy mode for the sake of consistency. +
Your bot can now get updates about posts in channels. Added new fields channel_post and edited_channel_post to Update.
+
+You can now update high scores to a lower value by using the new force parameter in setGameScore. Handy for punishing cheaters or fixing errors in your game's High Score table.
+
+- Starting today, messages with high scores will be updated with new high scores by default. Use disable_edit_message in setGameScore if you don't want this. +
- The edit_message parameter from setGameScore is no longer in use. For backward compatibility, it will be taken into account for a while, unless disable_edit_message is passed explicitly. +
- Added the new field forward_from_message_id to Message. +
- Added the new parameter cache_time to answerCallbackQuery. Will eventually work in Telegram apps — somewhere after version 3.14, maybe 3.15. +
- Renamed hide_keyboard to remove_keyboard in ReplyKeyboardRemove for clarity. hide_keyboard will still work for a while for backward compatibility. +
