v6.8.0

• You wouldn't download a car, but now when you download an MP3 voice note it will be saved with the proper file extension.
• Quickly begin typing a message after attaching a file, or just hit Enter/Return to send the file without any extra clicks. Thanks, @zyphlar!
• The send button in the large composition view has been brought into alignment. Thanks, @hackerbirds!
• If you are the only person in a group (so far) and you attempt to begin a group call, now you can join the call and start talking to yourself right away instead of waiting for the call to ring. Thanks, @lamemakes!
