Telegram is the only mass market messaging app with open source apps. Since 2013, this not only allows independent researchers to verify the integrity of end-to-end encryption, but also helps look for vulnerabilities (or backdoors ).
As of this update, Telegram becomes the first messaging app to allow you to independently verify that the code on GitHub is the exact same code that was used to build the app you downloaded from App Store or Google Play. Security researchers are welcome to check out our Guide to Reproducible Builds for iOS and Android.
But we know security isn‘t the only reason you love Telegram – so we’ve also added dozens of new features and improvements. Gather round, this blog post is a long one.
Using the new theme editor in Chat Settings (or Appearance Settings on iOS), you can quickly tweak the style of elements in Telegram chats and add awesome gradients to both your messages and your background. Switch between tabs (Main Color, Background, My Messages) to see how deep this rabbit hole goes:
Once you’re done editing, you can quickly share the result of your work with friends so that they can continue tuning your theme.
By the way, this update includes dozens of new cool patterns you can apply to your background. Our favorites are the Math and Parisian motifs, but there‘s also one we made especially for New Year’s Eve.
There are new patterns with cats as well. And space. And cats in space. No time to explain, go check them all out.
Not in a creative mood? Not a problem – we’ve added a boatload of new predefined color schemes for Telegram’s default themes. The theme of your dreams may be just a few taps away, try the new options under Classic, Night, Day, etc.
Some things are best served fresh, like sushi and today‘s hot memes. For messages that have to be delivered at the perfect moment, we’ve added the option to schedule messages to be sent when your recipient comes online.
Now you can slide your message in with the morning post – or time a funky duck sticker for the exact moment a meeting gets boring.
Note that this option is only available if you are allowed to see your recipient’s online status. You can still sneak out of bed without anyone noticing.
Location sharing has been updated to make finding venues easier. You can now tap a place directly on the map to select it, rather than scrolling through a list of all the power converter purveyors in Tosche Station.
The Search function allows you to easily jump between messages containing a keyword – or sent by a particular person, or even from a certain day. Tapping the bottom bar will now switch to list view in case you want to see all the results on one page.
On iOS, you can also select several messages without leaving Search Mode. (Before you ask, this feature was already available on Android.)
You’ve always been able to share files of up to 1,5 GB, but podcasts and audiobooks now get special treatment. Telegram apps will remember your last position when resuming playback of audio files longer than 20 minutes.
If you’d like to make podcasts get to the point a little faster, try the new 2x button (which you already know from voice messages). We’ve eliminated voice chipmunking in 96.8% of cases.
On iOS, you can skip forward and back with high-precision scrubbing: just hold on the progress bar and slide your finger down, then left or right.
Telegram has shielded your eyes in dark places with Night Mode since 2017. The power of the sun and moon are now even easier to control, with the Night Mode Switch at the top of the menu. Tap the moon icon and watch the sun rise and fall at your whim.
Maps have also joined the dark side in Night Mode, so you don’t accidentally burn yourself while browsing locations late in the evening. Ve do as the count vills. (•,..,•)
On iOS, dark maps turn on and off with the system dark mode. Speaking of which, we recently added the option to sync your Telegram theme with system dark mode on iOS 13.
