+# 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]).

+
+# 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.

Zsin Skri	ef57f1021c	Revert "Don't send delivery receipts to unencrypted private chat portals. Fixes #483 " This reverts commit `a4595b427d`. Commit `a4595b4` avoids sending delivery receipts to rooms that do not contain the bridge bot. That was necessary as trying to send a read marker would automatically attempt to join the bridge bot to the room. That join without invite would fail, hence #483. But since https://github.com/mautrix/python/commit/f272f16a1d151a1c6612c9349776eda985c8ea3e we no longer attempt to join the sender of read receipts, fixing #483 without necessarily sacrificing the delivery receipt functionality. Thus: - `a4595b4` is no longer necessary, its original purpose is fulfilled by f272f16. - `a4595b4` prevents delivery receipts from working in unencrypted rooms. - This reverts `a4595b4`, thus enabling delivery receipts in unencrypted rooms.	2022-07-17 20:57:17 +02:00

Cy Nhr	50cd878f13	Include command prefix in game and poll messages Game and poll messages send by the bridge to matrix each include a command the receiver might want to run (to play the game or to vote in the poll). But these command suggestions did always include the "!tg" command prefix, even if the command prefix was changed to a different value in the config. That could lead to the bridge ignoring the exact command it suggested earlier. With this commit, these messages contain the correct command prefix as defined in the config so that the command suggestions can be executed by the user without manually correcting the prefix.	2022-06-18 20:23:59 +02:00
