For Android Users, you can now use Android Pay to pay for bot payments. The app also shows photos and videos together while sharing them through the app.
Another noticeable feature is for supergroup users. Supergroups can now have up to 10,000 users. Admins now have more granular controls, including selecting what other admins can do within the group, prevent certain users from performing certain tasks like sending messages, media, stickers, etc. (this is really interesting) within the group, and seeing what other admins have been up to in Recent Actions in the admins page.
More importantly, Telegram also added an option to set up your own proxy server as an anti-censorship tool.
Meanwhile, this latest update isn’t for mobile devices alone but the desktop apps have also been updated to reflect these changes.
