New tab for ad creation has appeared on the test server in Telegram Ads — Users.

Previously, only Search, Bots, and Channels tabs were available when creating an ad. Now Telegram is testing a separate targeting type focused directly on users.

What can be configured in the new target:
× Ad placement — ad format: Message in Channel or Banner in Video;
× Target countries — countries where the ad will be shown. One country must be selected;
× Target locations — specific cities or locations within selected country;
× Target user languages — user languages;
× Target topics — interest topics for ad targeting;
× Only target users interested in all selected topics — separate toggle that shows ads only to users who match all selected topics at once;
× Target channel audiences — lets you choose channel audiences to target;
× Target device type — All devices, iOS, Android, Mobile, or Desktop;
× Show this ad in channels related to Politics & Incidents only — separate toggle to show ads only in channels related to this category;
× Exclude topics — topic exclusions;
× Exclude channel audiences — exclusions by audiences of specific channels;
× Do not show this ad in channels related to Politics & Incidents — separate toggle to fully exclude this channel category.


Telegram is moving toward much more precise ad targeting — not just where ad is shown, but who exactly sees it: by interests, languages, countries, specific locations, device type, and audiences of specific channels.

!!! UPD: Some say this feature has been there for a while — I only noticed it now. So this is more of an FYI.

Stars. Squares. A Rorschach test of two high fiving bears. Just a few of the new video message shapes released today.

This is what the warning will look like when a user is using an unofficial Telegram client. @telelakel
The warning label for users who use unofficial Telegram clients is now working on production server. Some accounts already have this mark — be careful if you have important messages in chats with such users.

This label is shown on users of the russian Telegram client, which is not safe to use.

🛡In Telegram Desktop v6.7.2 and Telegram Beta for Android v12.6.4 (6662), TLS ClientHello generation was updated for connections over MTProto proxy. This addresses TLS fingerprint quirks that could previously make such traffic easier for DPI systems to detect and potentially block.

MTProto proxy is used to obfuscate Telegram traffic. When a connection is established, the client sends a TLS ClientHello message, and its parameters can be analyzed by DPI systems to identify the traffic type.

The issue was that the previous TLS ClientHello implementation produced an unusual TLS fingerprint. In Telegram Desktop, for example, 0xfe02 was used instead of 0xfe0d, and there were 20 bytes of random data instead of 32. This increased the likelihood of accurate MTProto proxy traffic detection.

After these changes, TLS ClientHello is now closer to the profile of regular browser traffic. This may make detection and blocking of MTProto proxy connections more difficult, especially in networks with active DPI filtering, including in Russia.

AI Editor for messages.
Filtering was added to «AI Editor». If a message contains offensive words, political phrases, and so on, you’ll get an «AICOMPOSE_ERROR_OCCURED» error.

@telelakel
🤖 Telegram previously restricted bot-to-bot interaction to avoid endless message loops, but now Bot-to-Bot communication is allowed in certain scenarios — opening up more complex agentic flows and new AI use cases. The feature already works in groups and through business mode, and to enable it for your bot, you just need to turn on Bot-to-Bot Communication Mode in @BotFather.

Stable Telegram for Android updated to v12.6.4 (6666). It adds new TLS ClientHello generation for MTProto Proxy, making traffic look more like regular browser traffic — so it should be harder to detect and block via DPI.

@telelakel
In the new update Telegram Desktop v6.7.4 (test update), an option to disable «AI Editor» was added to experimental settings.

Based on recent changes on test Fragment, a new payment flow for Stars is being prepared. Code now includes currency: 'usdt', a separate ERC20 popup, and a new payment flow replacing the standard Wallet.sendTransaction — which is now commented out in this part. QR for top-up address was also added, along with a dedicated interface for this process. Looks like they’re testing a separate USDT payment flow for buying Stars.
