iOS v7.10
Official Release Notes
- Now you can react with any emoji during a Signal call. Smile even if your camera is off, share a heart if you love what you're hearing, or vote for sushi instead of pizza without saying a word. And you'll even see an animation of everyone's emojional outburst if enough people in the call react with the same emoji all at once.
Upcoming Features
- More work completed for the upcoming cloud backups feature [src]
