```

### Conversations 2.0.0 *(October 19, 2021)*

* [aar](https://sdk.twilio.com/android/conversations/releases/2.0.0/twilio-conversations-android-2.0.0.aar)
* SHA-256: `f746e085d3e95d45f98a4489a49080347cf0bf05850f0695243224b38b219d9d`
* [Documentation](https://sdk.twilio.com/android/conversations/releases/2.0.0/docs/)

**Breaking changes**

* **Major under-the-hood improvement** (the "Sessionless" protocol). This improvement is designed primarily for improved reliability. While this is not a breaking code change, it does carry a meaningful impact on timing:
  * SDK commands will return success or failure up to \~10% more quickly than before.
  * Real-time updates of data are now likely to arrive after the command completes. For example, `Conversation.updateAttributes()` will resolve successfully while `Conversation#attributes` still contains the old value. To see the new value, we recommend waiting for an `#updated` event.
* Some error messages have changed. For example, trying to leave a conversation you're not part of will return error `50432, Participant not found` instead of `50400, User not member of channel`.
* Passing `null` to `Conversation.sendMessage` will result in the message body being an empty string.
* `User.updateFriendlyName` no longer accepts `null` as the value.
* `Conversation.updateFriendlyName` no longer accepts `null` as the value.
