• Feeling ❤️‍🔥 or 😶‍🌫️ ? You can express yourself with a new batch of emoji, whether you're :whispering or :YELLING as you search. Thanks @hiqua!
• If you're in Anguilla, maybe you've felt left out. We now turn all top-level domains in place since 2010 into links - so both gov.ai and brain.ai will be clickable just like signal.org. Thanks @jojomatik!
• We heard you like to zoom in on images. We added oomph to your zoom, so even small images can go all the way full screen.
• Did you know that if disappearing messages are enabled, even the 'This message was deleted' notification will go away when it expires? It's no longer a mystery - you'll see the countdown and timestamp right on the message.
