+# (unreleased)
+
+* Added support for message reactions
+* Added support for spoiler text.
+
+# v0.11.0 (unreleased, 2021-12-??)
+
+* 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.
+* 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.

+
+* Added options to bridge archive, pin and mute status from Telegram to Matrix.
+* Added custom fields in Matrix events indicating Telegram gifs.

+
+## 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]).

+* Support for showing the individual slots in :slot_machine: 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.

+
+# 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.

+
+## 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]).

+
+### Added

+  (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.
+

+[#145]: https://github.com/mautrix/telegram/issues/145
+
+## rc4 (2018-05-29)
+
+* ~~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

+  * 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
