FYI about Erase All Data.

When you use "erase all data", alongside secret chats and downloaded media, only few settings are lost (complete list below). It affects only the account you are using it from. No data is erased on other accounts.

Always use this feature instead of logging out / signing in back. Logging out/logging in back now has no benefits at all, never do it.

Here's the list of what's deleted and can't be recovered:

- All secret chats
- Mentions/pinned message notification settings are reset to default
- Info about used hashtags
- Info about used inline bots
- Active live locations
- Bot keyboards in many groups
- Information about imported contacts (they'll be re-imported again, not a big deal)
- All incomplete active requests (e.g. unsent & failed outgoing messages)
- All shown notifications (they hide automatically once you perform this action)

If none above is essential for you, feel free to use this feature periodically.

0.21.7.1144 RC

- When you terminate Telegram X session from another device, all downloaded media will be erased as well. When Google Play Services are installed, Telegram X and TDLib will do its best to remove all data without need in opening the app once the device goes online.

This might be helpful in case your device is lost or stolen. You never know when this might happen, so be sure to keep Telegram X up-to-date.

Note this does not yet apply to media files which have been copied through "Save to Gallery/Downloads/Music" button;

- Improved push subnoscription. All beta users will be resubscribed to notifications after updating to this version as well.
- Fixed several log-in/log-out bugs
- Fixed polls can't be forwarded without re-entering the chat
- Updated TDLib: minor bugfixes

Next one will be stable, as I finish working on a change log (+ couple minor things).

0.21.7.1145 RC

Yet still RC, but should ready to be promoted to stable anytime. I'll make a separate post, if it will be promoted to stable.

- Log files in Settings > Data and Storage > Storage Usage
- Hint when trying to clear Local Database
- App change log is now sent only to active account after you get connected to Telegram
- Improved animations in the app menu when current user data has been changed (photo, name, phone)

- Fixed crash when trying to open some IV2.0 links, which are not supported
- Fixed missing avatar in app menu after signing in
- Fixed incorrectly shown notification text when someone joins public supergroup ("Returned to the group")
- Fixed lock button is displayed as unlocked when instant auto-lock enabled
- Fixed incorrect connection state detection while initializing the app
- Fixed empty string while deleting both non-revokable & revokable messages

There'll probably be one last Storage Usage screen improvement that will help saving even more disk space. But probably not. No other changes are planned.

0.21.7.1147 RC

- Added new Storage Usage fields: Settings and Themes, Localizations, Drawings and Junk Files.
- Slightly improved look of Data and Storage, Storage Usage and Network Usage screens
- Option to show all chats on Storage Usage screen, when there are too many of them
- Hint when using Erase All Data that it does not affect other accounts.

You may receive change log one more time after updating to this version, that's OK.

0.21.7.1151 is now published for all users.

For those who are new to this channel:

1. RC: Release Candidate. Means this version is ready to be uploaded as stable;
2. beta: This version isn't ready to go to stable because of unfinished work on some features / critical changes that could have broke something;
3. Both RC and beta versions are published on beta track, so you need to be subcribed to beta updates in order to receive them;
4. I publish change logs about the same time I upload the version to Google Play, but it can take from several minutes to couple hours to arrive;
5. For change log translations look out for local Telegram-related channels, there's no hidden team behind this channel.

Also added temporary hint for those who look for EmojiOne, which are now JoyPixels (which nobody recognizes yet).

These all changes do not require app update.

I guess the only thing I need now is blob version of channel logo. 🤔

0.21.8.1159 beta

Reworked text & emoji rendering, and how their bounds get calculated.

- Reworked text rendering. For default text size nothing should have changed visually. For others:
1. Proper bubble height calculation
2. Proper touch detection
3. Proper link press highlighting
4. More comfortable line spacing while using larger text size
5. Any system font should work properly inside message texts & media captions

- Reworked emoji rendering:
1. Emojis are now slightly bigger
2. Better positioning, especially in chats list and message input
3. While using larger text sizes, emojis will now position properly
4. Faster emoji rendering
5. Smoothier scrolling in the emoji keyboard
6. Added little spacing between twitter emojis

- Changed the way text & emoji bounds get calculated
- Text size now affects link previews as well
- Updated ExoPlayer to 2.10.0

Bugfixes

- Fixed rare crash when switching between emoji sets
- Fixed rare crash while processing messages
- Fixed incorrect bubble sizes when changing text size in settings
- Fixed transparent line glitches between items when opening options menu (e.g. when tapping on a message)

In case something looks broken after updating to this version, send screenshot as a document with all other essential information in the caption. (it's expected that something could have broken on customizable Android builds)

FYI new text rendering affects only messages, shared media, inline results and few other places.
