Telegram has added content protection support to enable users to block others from saving or forwarding posts shared in groups and channels.
To enable content protection, Group and Channel owners have to restrict message forwarding in their chat, also blocking screenshotting via Android security policies and removing the ability to save media from posts.
"With this update, we're helping creators protect the content they publish on Telegram and ensure that it is available only for their intended audience," the Telegram Team said.
Today's update also comes with new ways to delete posts by date, manage connected devices, and post anonymously in public groups and channel comments.
Some mobile users will also be offered to receive login calls from Telegram starting today instead of SMS codes to confirm their identity by entering several digits of the phone number that called.
This new version also added support for responses to join requests, global chat themes on Android, text recognition on iOS 13 and later, redesigned contact info on iOS, and the ability to format Text in media captions on iOS. Today's update comes after Telegram launched a new advertising program dubbed Ad Platform for public channels in late October, offering them the opportunity to display sponsored messages as a way to monetize the platform's massive user base.
