Telegram 5.8 lets you add anyone to your Telegram contacts – even if you don’t have their number.

If you’re looking to exchange contact info with people standing next to you, try the new Add People Nearby section in Contacts. You will see other users within 100 meters who are also viewing this section at the same time.

The People Nearby section also shows Groups Nearby –public chats related to places around you. As of today, anyone can host location-based group chats in their city.

We’ve also added a tool to transfer group ownership and enhanced notification exceptions to all apps.

Additionally, iOS users can now use Siri shortcuts and change the app icon (in Settings > Appearance).
