Api 5.5 is here. Rejoice.

• Doc note: 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.

• Doc note/potential shortcut: 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.

• New methods, nedds shortcuts at : Added the methods banChatSenderChat and unbanChatSenderChat for banning and unbanning channel chats in supergroups and channels.

• Chat addition: Added the field has_private_forwards to the class Chat for private chats, which can be used to check the possibility of mentioning the user by their ID.

• Chat/Message addition: Added the field has_protected_content to the classes Chat and Message.

• Message addition: Added the field is_automatic_forward to the class Message.

• Evaluate if worth adding to channel post/forward method docs: 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.

• Evaluate if worth adding to channel post: 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. Edit: Decided to not add it.
