TG Android Source v5.2.1 has been released

For DrKLO's standards the pace is picking up! Only about a month of delay! A change of heart? We'll see.
The commit is squashed as usual.

44 days are a new record for DrKLO, but his idea of Open Source is still questionable. Here's a good comment summarizing the current state of affairs:
Telegram v5.3 has been released

The source code has not been updated as usual. No sign of the promised Telegram X either.

Android Telegram v5.3.1 has been released - including source!

- Bug fixes

A source release on the same day is unheard of. Did we do it? Well, the commit is squashed as usual and they do not accept any input like most open source projects, but timely source releases are a great improvement!

If you know of any worthy privacy respecting, FLOSS clients get in touch! (@granskog) Telegram-FOSS for Android still seems to be the only client that cares about privacy. Most are clones with added bloat.

Android Telegram Source v5.4 has been released

The new pace is still not like regular FOSS projects where the source is released with the binaries but exceptionally great considering their past behaviour! We will not spam you with source update notifications if this becomes the new normal and only send changes and other info. We will see how the situation develops. :)

This update has not been marked as "suggested" in F-Droid yet, but you can install it by searching for Telegram, clicking on versions (scroll down) and then selecting 5.4 manually.

Android Telegram v5.5 has been released

A phenomenal update! So far you could delete messages (for both ends) in regular chats only for 48h. Now you can do so indefinitely - and any message. Should you or the other person have sent private information you can now delete it, completely.

If anyone from the Telegram team is reading this:
This should be the default option as there is no reason to not delete for both ends. If you accidentally forget about setting the checkbox there is no way to fix that currently.

You should still use secret chats as they are end-to-end encrypted and you can already delete as you wish there. Regular chats are a convenience feature due to being session-independent, but their impact on privacy depends entirely on Telegram's organisation not lying to us. We have seen virtually any big company/organisation lie in recent history so you may not want to rely on it. Government pressure to eliminate or at least backdoor encryption is also growing stronger, see Australia and UK for the most prominent examples.

This update is a huge committment to privacy nonetheless which is unheard of on other platforms. Not even a certain fancy, fully FOSS messenger offers this level of control. The perpetrator shall not be named..

Another extremely important aspect is forwarding privacy: So far anybody could forward your messages anywhere - with a permanent link to your profile. Now you can disable that in privacy settings. The forwarded message will unfortunately still show your name outside of the regular text message. You will still have a certain level of plausible deniability, but having the name as plain text would be a more elegant solution since anyone could have created a message like that.

Full changelog:

- Delete any message on both ends in any private chat, anytime.
- New privacy settings for message forwarding and profile pictures.
- Redesigned panel for Emoji, GIFs and Stickers with new search.
- Emoji suggestions for the first word you type in a message.
- Streaming support for GIFs and video messages.
- Search in Settings.
- TalkBack support.
- Improved call quality.

Again no source release this time, which is especially aggravating seeing how this update has very desirable features. Recent source releases have been relatively quick though so let's hope we'll get lucky again! (And pray to the F-Droid build server 😅)

In the meantime you can enable forwarding privacy via TG-Desktop if you like. Uninstalling your current Telegram-FOSS would invalidate all your secret/E2E chats.

The new privacy features might be killed again, vote now
an impromptu post due to urgency, a detailed article on Telegram in general may be posted at a later date

We just got some much needed privacy features on Telegram but current polls show they might kill it again because some people don't understand how the internet works.

If we want to control our data and not have our data control us we should've never used the old style regular chat/PM system of Telegram and should not do so going forward. Anything you write can and will be used against you. Messages are easily taken out of context. The true abuse lies in the easy exploitation of random data - and politics prove that on a daily basis.

Many of our more non-techy friends and family are also prone to accidental oversharing and we easily end up with our most private data on other peoples' computers ("the cloud"). The new features allow rectifying this easily. The old system does not.

Above is the official poll on the matter. I firmly believe in freedom of choice and speech - but if you care about privacy, and I suppose you do since you're reading this, I strongly advise voting yes. We don't often get privacy features from Telegram. There is still no visible intent to add E2E to TG-Desktop for instance. This decision may just impact the future path of Telegram.

Quick info:

old regular chats: 48h limit for deletion, only deleting your own possible
new regular chats: no limit for deletion, deleting any message possible

E2E/secret chats are unchanged: no limit for deletion, deleting any message possible
groups are unchanged: no limit for deletion, obviously only deleting your own messages possible

Disclaimer:

Malicious parties can always log on their own. But you always have plausible deniability. The important aspect lies in
a. removing data from 3rd party servers ("the cloud")
b. unlinking your messages from your identity

This is given with the new update. The only requirement is that we trust Telegram to not lie to our face as mentioned in the previous post. Truly private discussions should only be had with TG-Foss and E2E.

Android Telegram v5.6 has been released

The last few posts spoke too soon - apparently Telegram and DrKLO have not changed one tiny bit. Still no source for v5.5 and not for v5.6 either. Anyway, some of the new features work in TG-Desktop already, but since there is no source yet, there is no deblobbed/FOSS build available yet either. You will be notified as soon as it happens.

Changelog:

- Swipe left on any chat to archive it.
- Swipe left on your archive to hide it from the chat list.
- Pin an unlimited number of chats in your archive.
- See who is online straight from the chat list and sharing menu.
- Select multiple chats in the chats list to delete, pin or archive them.
- Choose between two-line and three-line chats in the chat list.
- Enjoy the redesigned app icon and menus throughout the app.
- Use the quick 'Forward' buttons when selecting messages in a chat.
- Copy links to messages in private groups to share with other group members.

We're back at the highly irregular pace.. At least it got released.
Telegram-FOSS should follow quickly as usual and you will be notified once you can download it from F-Droid.

Android Telegram v5.7 has been released

TG-Desktop, macOS, iOS have been updated as well. No source for Android has been released, as is usual with @DrKLO, who is still unable to understand the spirit of open source. Source is to be included in the release or your project is not open source. Randomly timed source releases are nothing but a marketing gimmick. The developers of TG-Desktop on the other hand understand that and have a regular repo.

Warning: This update can compromise your privacy. If you have the number of a person saved on your phone the other person will now see your number too, even if they did not originally have it. You need to disable this in privacy settings. Phone number display defaults to "my contacts", not "none".

The new feature to link a discussion group to a channel has a caveat to be aware of: it sets chat history to enabled, meaning every bot/crawler out there can grab your past discussions before you can ban it.

Changelog:

- Choose who can see your phone number with granular precision in Privacy & Security settings.
- Add group chats to "Always/Never Share" exceptions for any privacy setting. Permissions will update as users leave and join the groups.
- Enjoy improved design when confirming actions, searching for messages and adding users to groups.
- View any public channel from the web, even if you don't have a Telegram account.

For group admins and developers:
- Connect a discussion group to your channel, subscribers will see a 'Discuss' button.
- Integrate bots seamlessly with web services. For example, see t.me/DiscussThis/2
