Version 2.7.2.

- Offer real goods and services for sale in any group,
channel or bot – Telegram doesn't charge a commission.
- Pay for goods securely using one of the 8 integrated
payment providers – Telegram doesn't collect your payment info.
- See how this works in our @TestStore.
- Schedule voice chats to let participants know about them in advance.
- View a countdown to the voice chat and get notified when it starts.
- Try two new, fully-featured versions of Telegram Web – both
supporting animated stickers, dark mode, chat folders and more:
https://webk.telegram.org/ and https://webz.telegram.org/.
