Telegram updated with new invitations system, better replies and favorite stickers
Favorite Stickers
Among the most representative new features included in the update is the new invitational system, which allows users to invite their friends who don't use Telegram to join the messaging service.
Furthermore, the update adds “Favorite Stickers,” a new feature that allows Telegram users with five or more sticker sets installed to mark individual stickers as “favorites” so that they can access them from the top of the sticker panel in the “star” category.
Finally, Twitch videos are now supported in the Telegram built-in player, which will allow users to watch streams in PiP (Picture-in-Picture) mode while chatting. A new indicator for signal strength has been added so that users can check it when on a Telegram voice call.
iOS users will now be able to edit any photo that's been pasted directly to a chat from clipboard before sending, whereas Android users can long tap to select multiple recipients when forwarding a message.
