# v0.13.0 (2023-02-26)
### Added
* Added `allow_contact_info` config option to specify whether personal names
and avatars for other users should be bridged.
* The option is only safe to enable on single-user instances, using it
anywhere else will cause ghost user profiles to flip back and forth between
personal and default ones.
* Added config option to notify Matrix room if bridging an incoming message
fails.
### Improved
* Updated Docker image to Alpine 3.17.
* Updated to Telegram API layer 152.
* Improved handling users getting logged out.
* Removed support for creating accounts, as Telegram only allows requesting SMS
login codes on the official mobile clients now.
* Replaced moviepy with calling ffmpeg directly for generating video thumbnails.
### Fixed
* Fixed handling Telegram chat upgrades when backfilling is enabled.
* Fixed file transfers failing if transfering the thumbnail fails.
* Fixed bridging unnamed files with unrecognized mime types.
* Fixed enqueueing more backfill.
* Fixed timestamps not being saved in `telegram_file` table.
* Fixed issues with old events being replayed if the bridge was shut down
uncleanly.
# v0.12.2 (2022-11-26)
### Added
* Added built-in custom emoji packs to allow reacting with any standard unicode
emoji from Matrix (note that only premium users can use custom emojis).
* Added infinite backfill using [MSC2716].
* The new system includes a backwards compatibility mechanism which uses the
old method of just sending events to the room. By default, MSC2716 is not
enabled and the legacy method will be used.
### Improved
* Redacting reactions on Matrix no longer removes the user's other reactions to
the same message (premium users can have up to 3 reactions per message).
* Changes to default user permissions on Telegram are now bridged.
* Added database index to make reaction polling more efficient
(thanks to [@AndrewFerr] in [#862]).
### Fixed
* Fixed provisioning API not working with URL-encoded parameters.

[@AndrewFerr]: https://github.com/AndrewFerr
[#862]: https://github.com/mautrix/telegram/pull/862
# v0.12.1 (2022-09-26)
### Added
* Support for custom emojis in reactions.
* Like other bridges with custom emoji reactions, they're bridged as `mxc://`
URIs, so client support is required to render them properly.
### Improved
* The bridge will now poll for reactions to 20 most recent messages when
receiving a read receipt. This works around Telegram's bad protocol that
doesn't notify clients on reactions to other users' messages.
* The docker image now has an option to bypass the startup script by setting
the `MAUTRIX_DIRECT_STARTUP` environment variable. Additionally, it will
refuse to run as a non-root user if that variable is not set (and print an
error message suggesting to either set the variable or use a custom command).
* Moved environment variable overrides for config fields to mautrix-python.
The new system also allows loading JSON values to enable overriding maps like
`login_shared_secret_map`.
### Fixed
* `ChatParticipantsForbidden` is handled properly when syncing non-supergroup
info.
* Fixed some bugs with file transfers when using SQLite.
* Fixed error when attempting to log in again after logging out.
* Fixed QR login not working.
* Fixed error syncing chats if bridging a message had previously been
interrupted.
# v0.12.0 (2022-08-26)
**N.B.** This release requires a homeserver with Matrix v1.1 support, which
bumps up the minimum homeserver versions to Synapse 1.54 and Dendrite 0.8.7.
Minimum Conduit version remains at 0.4.0.
### Added
* Added provisioning API for resolving Telegram identifiers (like usernames).
* Added support for bridging Telegram custom emojis to Matrix.
* Added option to not bridge chats with lots of members.
* Added option to include captions in the same message as the media to
implement [MSC2530]. Sending captions the same way is also supported and
enabled by default.
* Added commands to kick or ban relaybot users from Telegram.
* Added support for Telegram's disappearing messages.
* Added support for bridging forwarded messages as forwards on Telegram.
* Forwarding is not allowed in relay mode as the bot wouldn't be able to
specify who sent the message.
* Matrix doesn't have real forwarding (there's no forwarding metadata), so
only messages bridged from Telegram can be forwarded.
* Double puppeted messages from Telegram currently can't be forwarded without
removing the `fi.mau.double_puppet_source` key from the content.
* If forwarding fails (e.g. due to it being blocked in the source chat), the
bridge will automatically fall back to sending it as a normal new message.
* Added options to make encryption more secure.
* The `encryption` -> `verification_levels` config options can be used to
make the bridge require encrypted messages to come from cross-signed
devices, with trust-on-first-use validation of the cross-signing master
key.
* The `encryption` -> `require` option can be used to make the bridge ignore
any unencrypted messages.
* Key rotation settings can be configured with the `encryption` -> `rotation`
config.
### Improved
* Improved handling the bridge user leaving chats on Telegram, and new users
being added on Telegram.
* Improved animated sticker conversion options: added support for animated webp
and added option to convert video stickers (webm) to the specified image
format.
* Audio and video metadata is now bridged properly to Telegram.
* Added database index on Telegram usernames (used when bridging username
@-mentions in messages).
* Changed `/login/send_code` provisioning API to return a proper error when the
phone number is not registered on Telegram.
* The same login code can be used for registering an account, but registering
is not currently supported in the provisioning API.
* Removed `plaintext_highlights` config option (the code using it was already
removed in v0.11.0).
* Enabled appservice ephemeral events by default for new installations.
* Existing bridges can turn it on by enabling `ephemeral_events` and disabling
`sync_with_custom_puppets` in the config, then regenerating the registration
file.
* Updated to API layer 144 so that Telegram would send new message types like
premium stickers to the bridge.
* Updated Docker image to Alpine 3.16 and made it smaller.
### Fixed
* Fixed command prefix in game and poll messages (thanks to [@cynhr] in [#804]).

[#804]: https://github.com/mautrix/telegram/pull/804
# v0.11.3 (2022-04-17)
**N.B.** This release drops support for old homeservers which don't support the
new `/v3` API endpoints. Synapse 1.48+, Dendrite 0.6.5+ and Conduit 0.4.0+ are
supported. Legacy `r0` API support can be temporarily re-enabled with `pip install mautrix==0.16.0`.
However, this option will not be available in future releases.
### Added
* Added `list-invite-links` command to list invite links in a chat.
* Added option to use [MSC2246] async media uploads.
* Provisioning API for listing contacts and starting private chats.
### Improved
* Dropped Python 3.7 support.
* Telegram->Matrix message formatter will now replace `t.me/c/chatid/messageid`
style links with a link to the bridged Matrix event (in addition to the
previously supported `t.me/username/messageid` links).
* Updated formatting converter to keep newlines in code blocks as `\n` instead
of converting them to `<br/>`.
* Removed `max_document_size` option. The bridge will now fetch the max size
automatically using the media repo config endpoint.
* Removed redundant `msgtype` field in sticker events sent to Matrix.
* Disabled file logging in Docker image by default.
* If you want to enable it, set the `filename` in the file log handler to a
path that is writable, then add `"file"` back to `logging.root.handlers`.
* Reactions are now marked as read when bridging read receipts from Matrix.
### Fixed
* Fixed `!tg bridge` throwing error if the parameter is not an integer
* Fixed `!tg bridge` failing if the command had been previously run with an
incorrectly prefixed chat ID (e.g. `!tg bridge -1234567` followed by
`!tg bridge -1001234567`).
* Fixed `bridge_matrix_leave` config option not actually being used correctly.
* Fixed public channel mentions always bridging into a user mention on Matrix
rather than a room mention.
* The bridge will now make room mentions if the portal exists and fall back
to user mentions otherwise.
* Fixed newlines being lost in unformatted forwarded messages.
[MSC2246]: https://github.com/matrix-org/matrix-spec-proposals/pull/2246
# v0.11.2 (2022-02-14)
**N.B.** This will be the last release to support Python 3.7. Future versions
will require Python 3.8 or higher. In general, the mautrix bridges will only
support the lowest Python version in the latest Debian or Ubuntu LTS.
### Added
* Added simple fallback message for live location and venue messages from Telegram.
* Added support for `t.me/+code` style invite links in `!tg join`.
* Added support for showing channel profile when users send messages as a channel.
* Added "user joined Telegram" message when Telegram auto-creates a DM chat for
a new user.
### Improved
* Added option for adding a random prefix to relayed user displaynames to help
distinguish them on the Telegram side.
* Improved syncing profile info to room info when using encryption and/or the
`private_chat_profile_meta` config option.
* Removed legacy `community_id` config option.
### Fixed
* Fixed newlines disappearing when bridging channel messages with signatures.
* Fixed login throwing an error if a previous login code expired.
* Fixed bug in v0.11.0 that broke `!tg create`.
# v0.11.1 (2022-01-10)
### Added
* Added support for message reactions.
* Added support for spoiler text.
### Improved
* Support for voice messages.
* Changed color of blue text from Telegram to be more readable on dark themes.
### Fixed
* Fixed syncing contacts throwing an error for new accounts.
* Fixed migrating pre-v0.11 legacy databases if the database schema had been
corrupted (e.g. by using 3rd party tools for SQLite -> Postgres migration).
* Fixed converting animated stickers to webm with >33 FPS.
* Fixed a bug in v0.11.0 that broke mentioning users in groups
(thanks to [@dfuchss] in [#724]).
[@dfuchss]: https://github.com/dfuchss
[#724]: https://github.com/mautrix/telegram/pull/724
# v0.11.0 (2021-12-28)
* Switched from SQLAlchemy to asyncpg/aiosqlite.
* The default database is now Postgres. If using SQLite, make sure you install
the `sqlite` [optional dependency](https://docs.mau.fi/bridges/python/optional-dependencies.html).
* **Alembic is no longer used**, schema migrations happen automatically on startup.
* **The automatic database migration requires you to be on the latest legacy
database version.** If you were running any v0.10.x version, you should be on
the latest version already. Otherwise, update to v0.10.2 first, upgrade the
database with `alembic`, then upgrade to v0.11.0 (or higher).
* Added support for contact messages.
* Added support for Telegram sponsored messages in channels.
* Only applies to broadcast channels with 1000+ members
(as per <https://t.me/durov/172>).
* Only applies if you're using puppeting with a normal user account,
because bots can't get sponsored messages.
* Fixed non-supergroup member sync incorrectly kicking one user from the Matrix
side if there was no limit on the number of members to sync (broke in v0.10.2).
* Updated animated sticker conversion to support [lottieconverter r0.2]
(thanks to [@sot-tech] in [#694]).
* Updated Docker image to Alpine 3.15.
* Formatted all code using [black](https://github.com/psf/black)
and [isort](https://github.com/PyCQA/isort).

# v0.10.2 (2021-11-13)
### Added
* Added extensions when bridging unnamed files from Telegram.
* Added support for custom bridge bot welcome messages
(thanks to [@justinbot] in [#676]).
### Improved
* Improved handling authorization errors if the bridge was logged out remotely.
* Updated room syncer to use existing power levels to find appropriate levels
for admins and normal users instead of hardcoding 50 and 0.
* Updated to Telegram API layer 133 to handle 64-bit user/chat/channel IDs.
* Stopped logging message contents when message handling failed
(thanks to [@justinbot] in [#681]).
* Removed Element iOS compatibility hack from non-sticker files.
* Made `max_initial_member_sync` work for non-supergroups too
(thanks to [@tadzik] in [#680]).
* SQLite is now supported for the crypto database. Pickle is no longer supported.
If you were using pickle, the bridge will create a new e2ee session and store
the data in SQLite this time.
### Fixed
* Fixed generating reply fallbacks to encrypted messages.
* Fixed chat sync failing if the member list contained banned users.

# v0.10.1 (2021-08-19)
**N.B.** Docker images have moved from `dock.mau.dev/tulir/mautrix-telegram`
to `dock.mau.dev/mautrix/telegram`. New versions are only available at the new
path.
### Added
* Warning when bridging existing room if bridge bot doesn't have redaction
permissions.
* Custom flag to invite events that will be auto-accepted using double puppeting.
* Custom flags for animated stickers (same as what gifs already had).
### Improved
* Updated to Telethon 1.22.
* Updated Docker image to Alpine 3.14.
### Fixed
* Fixed Bridging Matrix location messages with additional flags in `geo_uri`.

# v0.10.0 (2021-06-14)
* Added options to bridge archive, pin and mute status from Telegram to Matrix.
* Added custom fields in Matrix events indicating Telegram gifs.
* Allowed zero-width joiners in displaynames so things like multi-part emoji
would work correctly.
* Fixed Telegram->Matrix typing notifications.
## rc1 (2021-04-05)
### Added
* Support for multiple pins from/to Telegram.
* Option to resolve redirects when joining invite links, for people who use
custom URLs as invite links.

(thanks to [@MadhuranS] in [#599]).
* Own read marker/unread status from Telegram is now synced to Matrix after backfilling.
* Support for showing the individual slots in 🎰 dice rolls from Telegram.
### Improved
* Improved invite link regex to allow joining with less precise invite links.
* Invite links can be customized with the `--uses=<amount>` and
`--expire=<delta>` flags for `!tg invite-link`.
* Read receipts where the target message is unknown will now cause the chat to
be marked as fully read instead of the read receipt event being ignored.
* WebP stickers are now sent as-is without converting to png.
* Default power levels in rooms now allow enabling encryption with PL 50 if
e2be is enabled in config (thanks to [@Rafaeltheraven] in [#550]).
* Updated Docker image to Alpine 3.13 and removed all edge repo stuff.
### Fixed
* Matrix->Telegram location message bridging no longer flips the coordinates.
* Fixed some user displaynames constantly changing between contact/non-contact
names and other similar cases.

### Fixed
* Fixed bug where syncing members sometimes kicked ghosts of users who were
actually still in the chat.
* Fixed sending captions to Telegram with `!tg caption` (broken in rc1).
* Logging out will now delete private chat portals, instead of only kicking the
user and leaving the portal in a broken state.
* Unbridging direct chat portals is now possible.
## rc1 (2020-10-24)
### Breaking changes
* Prometheus metric names are now prefixed with `bridge_`.
* An entrypoint script is no longer automatically generated. This won't affect
most users, as `python -m mautrix_telegram` has been the official way to start
the bridge for a long time.
### Added

* Automatic backfilling of old messages when creating portals.
* Automatic backfilling of missed messages when starting bridge.
* Option to update `m.direct` list when using double puppeting.
* PNG thumbnails for animated stickers when converted to webm.

(requires Synapse 1.22 or higher).
### Improved
* Switched end-to-bridge encryption to mautrix-python instead of a hacky
matrix-nio solution.
* End-to-bridge encryption no longer requires `login_shared_secret`, it uses
[MSC2778] instead (requires Synapse 1.21 or higher).
* The bridge info state event is now updated whenever the chat name or avatar changes.
* Double puppeting is no longer limited to users on the same homeserver as the bridge.
* Delivery receipts are no longer sent in unencrypted private chat portals, as
the bridge bot is usually not present in them.
### Fixed
* File captions are now sent as a separate message like photo captions.
* The relaybot no longer drops Telegram messages with commands.
* Bridging events of a user whose power level is malformed (i.e. a string
instead of an integer) now works.

* Removed avatars are now synced properly from Telegram, instead of leaving the
last known avatar forever.
* Fixed admin detection on Telegram-side relaybot commands
(thanks to [@davidmehren] in [#468]).

* Support for bridging animated stickers (thanks to [@sot-tech] in [#366]).
* Requires [LottieConverter](https://github.com/sot-tech/LottieConverter),
which is included in the docker image.
* Can be [configured](https://github.com/mautrix/telegram/blob/v0.7.0-rc1/example-config.yaml#L174-L187).

for max length of displayname, with the default being 100.
* Separate [config option](https://github.com/mautrix/telegram/blob/v0.7.0-rc1/example-config.yaml#L232-L238)
for `m.emote` formatting of logged in users.
* Streamed file transfers and parallel telegram file download/upload.
* Files are streamed from telegram servers to the media repo rather than

* Changed default port to 29317.
* Mentions are now marked as read on Telegram when bridging read receipts using
double puppeting.
* Kicking or banning the bridge bot will now unbridge the room.
* Shrinked Docker image from 151mb to 77mb.
### Fixed
* The bridge will no longer crash if one user's startup fails.
* (hopefully) Incorrect peer type being saved into database in some cases.
* File names when bridging to Telegram.
* Alembic config interpolating passwords with `%`.
* A single chat failing to sync preventing any chat from syncing.
* Users logged in as a bot not receiving any messages.
* Username matching being case-sensitive in the database and preventing
telegram->matrix pillifying.
* IndexError if running `!tg set-pl` with no parameters.

separate messages.
## rc4 (2019-03-16)
* Added verbose flag to migration script.

* Removed remaining traces of ORM that might have been the causes of some other
database problems.
* Removed option to use lxml in HTML parsing as it was messing up emoji offset

[#290]: https://github.com/mautrix/telegram/pull/290
## rc3 (2019-02-16)

[#203]: https://github.com/mautrix/telegram/pull/203
## rc1 (2018-08-05)
### Added
* Logging in with a bot
(see [docs](https://docs.mau.fi/bridges/python/telegram/authentication.html#bot-token) for usage).
* You can log in with a personal Telegram bot to appear almost like a real
user without logging in with a real Telegram account.
* Replacing your Telegram account's Matrix puppet with your Matrix account
(see [docs](https://docs.mau.fi/bridges/general/double-puppeting.html) for usage).
* Formatting options for relaybot messages.
* Real displaynames are now supported and enabled by default.
* State events (join/leave/name change) can be independently disabled by
setting the format to a blank string.
* New config sections
* Proper log config, including logging to file (by default)
* Proxy support (requires installing PySocks)
* Separate field for appservice address for homeserver
(useful if using a reverse proxy).
* New permission levels to allow initiating bridges without allowing puppeting
and to allow Telegram puppeting without allowing Matrix puppeting.
* Telematrix import script (see [docs](https://docs.mau.fi/bridges/python/telegram/migrating-from-telematrix.html) for usage).
* Provisioning API (see [docs](https://docs.mau.fi/bridges/python/telegram/provisioning-api.html) for more info).
* DBMS migration script (see [docs](https://docs.mau.fi/bridges/python/telegram/dbms-migration.html) for usage).
### Improved
* Tabs are now replaced with 4 spaces so that Telegram servers wouldn't change
the message.
* Help page now detects your permissions and only shows commands you can use.
* Moved Matrix state cache to the main database. This means that the
`mx-state.json` file is no longer needed and all non-config data is
stored in the main database.
* Better lxml-based HTML parser for Matrix->Telegram formatting bridging.
lxml is still optional, so the old parser is used as fallback if lxml is not
installed.
* Disabled Telegram->Matrix bridging of messages sent by the relaybot.
Can be re-enabled in config if necessary.
### Fixed
* A `ValueError` in some cases when syncing power levels.
* Telegram connections being created for unauthenticated users possibly
triggering spam protection connection delays in the Telegram servers.

* ~~Fixed~~ Added Postgres compatibility.
* Fixed manual bridging (`!tg bridge`) for unauthenticated users.
* Fixed inviting unauthenticated Matrix users from Telegram (via `/invite <mxid>`).
* Changed Alembic to read database path from the config, so editing `alembic.ini`
is no longer necessary. Use `alembic -x config=/path/to/config.yaml ...` to
specify the config path.
## rc3 (2018-05-25)
* Reworked Dockerfile to remove virtualenv and use Alpine packages (thanks to
[@jcgruenhage] in [#142]). This fixes webp->png conversion for stickers.

* Moved mautrix-appservice-python to separate repository.
* Switched to telethon-session-sqlalchemy to have the session databases in the main database.
