@@ -0,0 +1,995 @@
+# v0.14.2 (2023-09-19)
+
+* **Security:** Updated Pillow to 10.0.1.
+* Added support for double puppeting with arbitrary `as_token`s.
+  See [docs](https://docs.mau.fi/bridges/general/double-puppeting.html#appservice-method-new) for more info.
+* Added support for sending webm and tgs files as stickers.
+* Updated to Telegram API layer 161.
+* Fixed cached usernames for Telegram users being cleared incorrectly, leading
+  to mentions not being bridged as usernames.
+* Fixed reaction bridging failing if the server running the bridge was rebooted
+  less than 12 hours ago.
+
+# v0.14.1 (2023-06-26)
+
+### Added
+* Added option to delete megolm sessions that were received before the
+  automatic ratcheting options were introduced.
+* Added config option to use IPv6 for Telegram connection
+  (thanks to [@exciler] in [#920]).
+
+### Improved
+* Dropped support for Python 3.8.
+* Updated Docker image to Alpine 3.18.
+* Added timeout for forward backfills to prevent it from getting stuck
+  permanently.
+
+### Fixed
+* Fixed `bridge.filter.users` config option not being read correctly.
+* Fixed proxy support to use python-socks instead of pysocks.
+
+[@exciler]: https://github.com/exciler
+[#920]: https://github.com/mautrix/telegram/pull/920
+
+# v0.14.0 (2023-05-26)
+
+### Added
+* Added fallback messages for calls and premium gifts.
+* Added options to automatically ratchet/delete megolm sessions to minimize
+  access to old messages.
+* Added option to not set room name/avatar even in encrypted rooms.
+* Implemented appservice pinging using MSC2659.
+* Added option to disable or filter bridging direct chats
+  (thanks to [@Steffo99] in [#892]).
+* Added options to specify different limits for forward and catchup backfilling
+  depending on chat type.
+
+### Improved
+* Improved handling logouts and certain connection errors.
+* Changed reaction bridging to preserve timestamps.
+* Disabled creating portals for DMs that don't have any messages when
+  `sync_direct_chats` is enabled.
+
+### Fixed
+* Fixed syncing mute status when portal is created through incoming message
+  rather than in startup sync.
+* Fixed bridge incorrectly trusting member list and kicking users when
+  supergroup has member list hidden.
+* Fixed sending messages after creating groups from Matrix using relaybot
+  instead of puppet (thanks to [@maltee1] in [#902]).

+
+# 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.
+
+[MSC2716]: https://github.com/matrix-org/matrix-spec-proposals/pull/2716
+[@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]).
+
+[MSC2530]: https://github.com/matrix-org/matrix-spec-proposals/pull/2530
+[@cynhr]: https://github.com/cynhr
+[#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).
+
+[lottieconverter r0.2]: https://github.com/sot-tech/LottieConverter/releases/tag/r0.2

+
+# 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`.
+* Editing encrypted messages will no longer add an asterisk on Telegram.
+* Matrix typing notifications won't be echoed back for double puppeted users anymore.
+* `AuthKeyDuplicatedError` is now handled properly instead of making the user
+  get stuck.
+* Fixed `public_portals` setting not being respected on room creation.
+
+# 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.
+* Command to update about section in Telegram profile info
+  (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]).

+
+# v0.9.0 (2020-11-17)
+
+* Fixed cleaning unidentified rooms.
+
+## rc3 (2020-11-12)
+
+### Added
+* Added retrying message sending if server returns 502.
+
+### Fixed
+* Fixed Matrix → Telegram name mentions.
+* Fixed some bugs with replies.
+
+## rc2 (2020-11-06)
+
+### Improved
+* Ephemeral event handling should be faster by not checking the database for
+  user existence.
+* Using the register command now sends a link to the Telegram terms of service.
+* The `bridge_connected` metric is now only set for users who are logged in.
+
+### 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
+* Support for logging in by scanning a QR code from another Telegram client.
+* 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.
+* Support for receiving ephemeral events pushed directly with [MSC2409]
+  (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.

+* Possibly fixed infinite loop of avatar changes when using double puppeting.
+
+## rc3 (2020-05-22)
+
+* Moved private information to trace log level.
+* Added `private_chat_portal_meta` option. This is implicitly enabled when
+  encryption is enabled, it was only added as an option for instances with
+  encryption disabled.
+* 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]).
+* Fixed bug handling `ChatForbidden` when syncing chats.
+
+[@davidmehren]: https://github.com/davidmehren

+
+## rc2 (2020-01-25)
+

+* Ignored `ChatForbidden` when syncing chats that was causing the sync to fail.
+* Fixed DB migration causing some incorrect values to be left behind.
+
+## rc1 (2019-11-30)
+
+### Important changes
+* Dropped Python 3.5 compatibility.
+* Moved docker registry to [dock.mau.dev](https://mau.dev/tulir/mautrix-telegram/container_registry).
+
+### Added
+* 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.

+* 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
+    downloading the whole file into memory.
+  * File transfers use multiple connections to telegram servers to transfer faster.
+  * Parallel and streamed file transfers can be enabled in the
+    [config](https://github.com/mautrix/telegram/blob/v0.7.0-rc1/example-config.yaml#L166-L169).

+### 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.

+
+* Fixed vulnerability in event handling.
+

+* Fixed some database problems.
+* 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

+## rc3 (2019-02-16)

+## 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.
+* Logging out if a portal had been deleted/unbridged.
+
+# v0.2.0 (2018-06-08)
+
+* No changes since rc6.

+
+## rc3 (2018-05-25)

+  * Optional HQ gif/video thumbnails using moviepy.
+  * Option to send bot messages as `m.notice`
+* Improved deduplication
+  * Matrix file uploads are now reused if the same Telegram file (e.g. a sticker) is sent multiple times
+  * Room metadata changes and other non-message actions are now deduplicated
+* Improved formatting bridging
+* Improved Telegram user display name handling in cases where one or more users have set custom display names for other users.
+* Fixed Alembic setup and removed automatic database generation.
+* Fixed outgoing message deduplication in cases where message is sent to other clients before responding to the sender.
+* Moved mautrix-appservice-python to separate repository.
+* Switched to telethon-session-sqlalchemy to have the session databases in the main database.
+* Switched license from GPLv3 to AGPLv3
+* Probably a bunch of other stuff I forgot
