Starting with Telegram 4.5, whenever you send multiple photos or videos they are grouped into albums. Each album can include up to 10 photos or videos, arranged in the chat as elegantly proportioned thumbnails. They will also result in one notification instead of ten on the recipient’s side.
See other features also added to the Version 4.5 of telegram:
1. Grouped Photos – Group media into an album when sharing multiple photos and videos. Choose the exact order of media you send.
3. Better Search – Find bots and public channels faster by typing their titles in Search. Popular bots and channels are shown first.
These features are available for both Android and iOS.
