Voice Chat Info
And More
- Added the type MessageAutoDeleteTimerChanged and the field message_auto_delete_timer_changed to the class Message.
- Added the parameter revoke_messages to the method kickChatMember, allowing to delete all messages from a group for the user who is being removed.

WARNING!
After one of the upcoming Bot API updates, some 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.

- In supergroups, if the bot receives a message that is a reply, it will also receive the message to which that message is replying – even if the original message is inaccessible due to the bot's privacy settings. (In other words, replying to any message in a supergroup with a message that mentions the bot or features a command for it acts as forwarding the original message to the bot).

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.

November 21, 2016
Bot API 2.3
- Modified bot privacy mode for the sake of consistency.

- The Chat field in the Message is now of the new type Chat.
- You can now pass a channel username (in the format
@channelusername

- You can now make new requests when responding to webhook updates.
August 15, 2015
