Telegram has released a new version of its app with two useful features.
If you need to send a message to a person, to a group chat or to post text in a Telegram channel, press and hold the send button until a menu pops up with the options "Send Without Sound" and "Schedule Message". Selecting the second one brings up a calendar with a clock, where you set the exact time of sending.

Reminders work on the same principle, except you schedule a message to yourself.

Telegram has also expanded chat theme settings, redesigned the menu with a message option, added more animated emoji and privacy settings.
