<!-- For those prowling deep in the shadows of the pillars supporting this page, here's a bonus non-winter themed version of the image: /file/464001695/1/nxVa_f-qKS8.216020/9da7686ded6f1e7bef -->
<p>Telegram is the only mass market messaging app with <a href="https://telegram.org/apps/#source-code">open source</a> apps. Since <strong>2013</strong>, this not only allows independent researchers to <strong>verify the integrity</strong> of end-to-end encryption, but also helps look for vulnerabilities (or <a href="https://t.me/durov/109">backdoors</a> <img class="emoji" src="//telegram.org/img/emoji/40/F09F9888.png" width="20" height="20" alt="😈" />).</p>
<p>As of this update, Telegram becomes the first messaging app to allow you to <strong>independently verify</strong> that the code on GitHub is the <strong>exact same code</strong> that was used to build the app you downloaded from <strong>App Store</strong> or <strong>Google Play</strong>. Security researchers are welcome to check out our <a href="https://core.telegram.org/reproducible-builds">Guide to Reproducible Builds for iOS and Android</a>.</p>
<p>But we know security isn&#39;t the only reason you love Telegram so we&#39;ve also added <strong>dozens of new features</strong> and improvements. Gather round, this blog post is a long one.</p>
<h4><a class="anchor" name="theme-editor-2-0" href="#theme-editor-2-0"><i class="anchor-icon"></i></a>Theme Editor 2.0</h4>
<p>Using the <strong>new theme editor</strong> in Chat Settings (or <em>Appearance Settings</em> on iOS), you can quickly tweak the style of elements in Telegram chats and add <strong>awesome gradients</strong> to both your messages and your background. Switch between tabs (Main Color, Background, My Messages) to see how deep this rabbit hole goes:</p>

<p>Once you&#39;re done editing, you can quickly <strong>share the result</strong> of your work with friends so that they can continue tuning your theme. </p>
<p>By the way, this update includes dozens of new <strong>cool patterns</strong> you can apply to your background. Our favorites are the <em>Math</em> and <em>Parisian</em> motifs, but there&#39;s also one we made especially for New Year&#39;s Eve.</p>

<p>There are new patterns with cats as well. And space. And cats <em>in</em> space. No time to explain, go check them all out.</p>
<!--Hardcore theme builders may also like the [Online Theme Editor](http://themes.telegram.org), which allows editing themes for Telegram apps across all platforms down to the tiniest details.-->
<h4><a class="anchor" name="new-predefined-colors" href="#new-predefined-colors"><i class="anchor-icon"></i></a>New Predefined Colors</h4>
<p>Not in a creative mood? Not a problem we&#39;ve added a boatload of new <strong>predefined color schemes</strong> for Telegram&#39;s default themes. The theme of your dreams may be just a few taps away, try the new options under Classic, Night, Day, etc.</p>

<h4><a class="anchor" name="send-when-online" href="#send-when-online"><i class="anchor-icon"></i></a>Send When Online</h4>
<p>Some things are best served fresh, like sushi and today&#39;s hot memes. For messages that have to be delivered at the perfect moment, we&#39;ve added the option to <a href="https://telegram.org/blog/scheduled-reminders-themes">schedule messages</a> to be sent when your recipient <strong>comes online</strong>.</p>
<p>Now you can slide your message in with the morning post or time a funky <a href="http://t.me/addstickers/FunkyGoose">duck sticker</a> for the exact moment a meeting gets boring.</p>

<p>Note that this option is only available if you are allowed to see your recipient&#39;s <strong>online status</strong>. You can still sneak out of bed without anyone noticing.</p>
<h4><a class="anchor" name="improved-venue-sharing" href="#improved-venue-sharing"><i class="anchor-icon"></i></a>Improved Venue Sharing</h4>
<p>Location sharing has been updated to make finding <strong>venues</strong> 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.</p>

<h4><a class="anchor" name="podcast-and-audiobook-support" href="#podcast-and-audiobook-support"><i class="anchor-icon"></i></a>Podcast and Audiobook Support</h4>
<p>You&#39;ve always been able to <a href="https://telegram.org/blog/6-years#january-2014">share files</a> of up to <strong>1,5 GB</strong>, but podcasts and audiobooks now get special treatment. Telegram apps will <strong>remember</strong> your last position when resuming playback of audio files longer than <strong>20 minutes</strong>.</p>
<p>If you&#39;d like to make podcasts get to the point a little faster, try the new <strong>2x button</strong> (which you already know from <a href="https://telegram.org/blog/unread-replace-2x#double-time-playback-for-voice-and-video-messages">voice messages</a>). We&#39;ve eliminated voice chipmunking in <strong>96.8%</strong> of cases.</p>

<p>When you&#39;re done listening to a voice message with your phone up to your ear, Telegram automatically records a reply - but now you can disable that by turning off <a href="https://telegram.org/blog/voice-2-secret-3">Raise to Speak</a> in your Chat Settings. </p>
<p>We found <strong>31</strong> other shiny bugs to fix and improvements to make on Android, just in time for your Telegram advent calendar. See if you can find them all.</p>

<p>Superman has had a hard time finding phone booths lately, so we added a way to swiftly <strong>switch accounts</strong> right from your home screen on <strong>iOS 13</strong>. Simply hold down on the app icon any time you need to change costumes.</p>

<p>The <strong>Storage Usage</strong> page has been <strong>redesigned</strong> to more quickly find the settings you&#39;re looking for. It also shows your device&#39;s storage status, and how much space all those other pesky apps are using compared to Telegram. Bigger, after all, is not always better.</p>
<p>You did know that with Telegram there&#39;s <a href="https://telegram.org/blog/cache-and-stickers">no need to store every silly meme</a> people ever sent you on your precious device, right?</p>

<p>Selecting multiple messages in a group or channel gives you the option to <strong>clear</strong> the chat&#39;s <strong>cache</strong>. Like we said, no need to store what you don&#39;t need but also no need to delete actual messages. Just keep things in the cloud, like the cool kids.</p>

<p>In case you&#39;re looking to leave some large groups and start fresh in the new decade, long member lists will <strong>collapse</strong>, so you can get to the <em>&#39;Leave Group&#39;</em> button without scrolling.</p>
<p>By the way, swiping on a group or channel from the chat list and selecting <em>&#39;Delete&#39;</em> is still the shortest way out, but now there is more than one way to leave the New Year&#39;s party early.</p>
