+* *(federation)* Added implementation of server name resolution and a basic
+  client for making federation requests.
+* *(crypto/ssss)* Changed recovery key/passphrase verify functions to take the
+  key ID as a parameter to ensure it's correctly set even if the key metadata
+  wasn't fetched via `GetKeyData`.
+* *(format/mdext)* Added goldmark extensions for single-character bold, italic
+  and strikethrough parsing (as in `*foo*` -> **foo**, `_foo_` -> _foo_ and
+  `~foo~` -> ~~foo~~)
+* *(format)* Changed `RenderMarkdown` et al to always include `m.mentions` in
+  returned content. The mention list is filled with matrix.to URLs from the
+  input by default.

+
+### beta.1 (2024-06-16)
+
+* *(bridgev2)* Added experimental high-level bridge framework.
+* *(hicli)* Added experimental high-level client framework.
+* **Slightly breaking changes**
+  * *(crypto)* Added room ID and first known index parameters to
+    `SessionReceived` callback.
+  * *(crypto)* Changed `ImportRoomKeyFromBackup` to return the imported
+    session.
+  * *(client)* Added `error` parameter to `ResponseHook`.
+  * *(client)* Changed `Download` to return entire response instead of just an
+    `io.Reader`.
+* *(crypto)* Changed initial olm device sharing to save keys before sharing to
+  ensure keys aren't accidentally regenerated in case the request fails.
+* *(crypto)* Changed `EncryptMegolmEvent` and `ShareGroupSession` to return
+  more errors instead of only logging and ignoring them.
+* *(crypto)* Added option to completely disable megolm ratchet tracking.
+  * The tracking is meant for bots and bridges which may want to delete old
+    keys, but for normal clients it's just unnecessary overhead.
+* *(crypto)* Changed Megolm session storage methods in `Store` to not take
+  sender key as parameter.
+  * This causes a breaking change to the layout of the `MemoryStore` struct.
+    Using MemoryStore in production is not recommended.
+* *(crypto)* Changed `DecryptMegolmEvent` to copy `m.relates_to` in the raw
+  content too instead of only in the parsed struct.
+* *(crypto)* Exported function to parse megolm message index from raw
+  ciphertext bytes.
+* *(crypto/sqlstore)* Fixed schema of `crypto_secrets` table to include
+  account ID.
+* *(crypto/verificationhelper)* Fixed more bugs.
+* *(client)* Added `UpdateRequestOnRetry` hook which is called immediately
+  before retrying a normal HTTP request.
+* *(client)* Added support for MSC3916 media download endpoint.
+  * Support is automatically detected from spec versions. The `SpecVersions`
+    property can either be filled manually, or `Versions` can be called to
+    automatically populate the field with the response.
+* *(event)* Added constants for known room versions.
+
+## v0.18.1 (2024-04-16)
+
+* *(format)* Added a `context.Context` field to HTMLParser's Context struct.
+* *(bridge)* Added support for handling join rules, knocks, invites and bans
+  (thanks to [@maltee1] in [#193] and [#204]).
+* *(crypto)* Changed forwarded room key handling to only accept keys with a
+  lower first known index than the existing session if there is one.
+* *(crypto)* Changed key backup restore to assume own device list is up to date
+  to avoid re-requesting device list for every deleted device that has signed
+  key backup.
+* *(crypto)* Fixed memory cache not being invalidated when storing own
+  cross-signing keys

+[#204]: https://github.com/mautrix/go/pull/204
+
+## v0.18.0 (2024-03-16)
+
+* **Breaking change *(client, bridge, appservice)*** Dropped support for
+  maulogger. Only zerolog loggers are now provided by default.
+* *(bridge)* Fixed upload size limit not having a default if the server
+  returned no value.
+* *(synapseadmin)* Added wrappers for some room and user admin APIs.
+  (thanks to [@grvn-ht] in [#181]).
+* *(crypto/verificationhelper)* Fixed bugs.
+* *(crypto)* Fixed key backup uploading doing too much base64.
+* *(crypto)* Changed `EncryptMegolmEvent` to return an error if persisting the
+  megolm session fails. This ensures that database errors won't cause messages
+  to be sent with duplicate indexes.
+* *(crypto)* Changed `GetOrRequestSecret` to use a callback instead of returning
+  the value directly. This allows validating the value in order to ignore
+  invalid secrets.
+* *(id)* Added `ParseCommonIdentifier` function to parse any Matrix identifier
+  in the [Common Identifier Format].
+* *(federation)* Added simple key server that passes the federation tester.
+

+[#181]: https://github.com/mautrix/go/pull/181
+[Common Identifier Format]: https://spec.matrix.org/v1.9/appendices/#common-identifier-format
+
+### beta.1 (2024-02-16)
+
+* Bumped minimum Go version to 1.21.
+* *(bridge)* Bumped minimum Matrix spec version to v1.4.
+* **Breaking change *(crypto)*** Deleted old half-broken interactive
+  verification code and replaced it with a new `verificationhelper`.
+  * The new verification helper is still experimental.
+  * Both QR and emoji verification are supported (in theory).
+* *(crypto)* Added support for server-side key backup.
+* *(crypto)* Added support for receiving and sending secrets like cross-signing
+  private keys via secret sharing.
+* *(crypto)* Added support for tracking which devices megolm sessions were
+  initially shared to, and allowing re-sharing the keys to those sessions.
+* *(client)* Changed cross-signing key upload method to accept a callback for
+  user-interactive auth instead of only hardcoding password support.
+* *(appservice)* Dropped support for legacy non-prefixed appservice paths
+  (e.g. `/transactions` instead of `/_matrix/app/v1/transactions`).
+* *(appservice)* Dropped support for legacy `access_token` authorization in
+  appservice endpoints.
+* *(bridge)* Fixed `RawArgs` field in command events of command state callbacks.
+* *(appservice)* Added `CreateFull` helper function for creating an `AppService`
+  instance with all the mandatory fields set.
+
+## v0.17.0 (2024-01-16)
+
+* **Breaking change *(bridge)*** Added raw event to portal membership handling
+  functions.
+* **Breaking change *(everything)*** Added context parameters to all functions
+  (started by [@recht] in [#144]).
+* **Breaking change *(client)*** Moved event source from sync event handler
+  function parameters to the `Mautrix.EventSource` field inside the event
+  struct.
+* **Breaking change *(client)*** Moved `EventSource` to `event.Source`.
+* *(client)* Removed deprecated `OldEventIgnorer`. The non-deprecated version
+  (`Client.DontProcessOldEvents`) is still available.
+* *(crypto)* Added experimental pure Go Olm implementation to replace libolm
+  (thanks to [@DerLukas15] in [#106]).
+  * You can use the `goolm` build tag to the new implementation.
+* *(bridge)* Added context parameter for bridge command events.
+* *(bridge)* Added method to allow custom validation for the entire config.
+* *(client)* Changed default syncer to not drop unknown events.
+  * The syncer will still drop known events if parsing the content fails.
+  * The behavior can be changed by changing the `ParseErrorHandler` function.
+* *(crypto)* Fixed some places using math/rand instead of crypto/rand.

+
+## v0.16.2 (2023-11-16)
+
+* *(event)* Added `Redacts` field to `RedactionEventContent` for room v11+.
+* *(event)* Added `ReverseTextToHTML` which reverses the changes made by
+  `TextToHTML` (i.e. unescapes HTML characters and replaces `<br/>` with `\n`).
+* *(bridge)* Added global zerologger to ensure all logs go through the bridge
+  logger.
+* *(bridge)* Changed encryption error messages to be sent in a thread if the
+  message that failed to decrypt was in a thread.
+
+## v0.16.1 (2023-09-16)
+
+* **Breaking change *(id)*** Updated user ID localpart encoding to not encode
+  `+` as per [MSC4009].
+* *(bridge)* Added bridge utility to handle double puppeting logins.
+  * The utility supports automatic logins with all three current methods
+    (shared secret, legacy appservice, new appservice).
+* *(appservice)* Added warning logs and timeout on appservice event handling.
+  * Defaults to warning after 30 seconds and timeout 15 minutes after that.
+  * Timeouts can be adjusted or disabled by setting `ExecSync` variables in the
+    `EventProcessor`.
+* *(crypto/olm)* Added `PkDecryption` wrapper.
+
+[MSC4009]: https://github.com/matrix-org/matrix-spec-proposals/pull/4009
+
+## v0.16.0 (2023-08-16)
+
+* Bumped minimum Go version to 1.20.
+* **Breaking change *(util)*** Moved package to [go.mau.fi/util](https://go.mau.fi/util/)
+* *(event)* Removed MSC2716 `historical` field in the `m.room.power_levels`
+  event content struct.
+* *(bridge)* Added `--version-json` flag to print bridge version info as JSON.
+* *(appservice)* Added option to use custom transaction handler for websocket mode.
+
+## v0.15.4 (2023-07-16)
+
+* *(client)* Deprecated MSC2716 methods and added new Beeper-specific batch
+  send methods, as upstream MSC2716 support has been abandoned.
+* *(client)* Added proper error handling and automatic retries to media
+  downloads.
+* *(crypto, bridge)* Added option to remove all keys that were received before
+  the automatic ratcheting was implemented (in v0.15.1).
+* *(dbutil)* Added `JSON` utility for writing/reading arbitrary JSON objects to
+  the db conveniently without manually de/serializing.
+
+## v0.15.3 (2023-06-16)
+
+* *(synapseadmin)* Added wrappers for some Synapse admin API endpoints.
+* *(pushrules)* Implemented new `event_property_is` and `event_property_contains`
+  push rule condition kinds as per MSC3758 and MSC3966.
+* *(bridge)* Moved websocket code from mautrix-imessage to enable all bridges
+  to use appservice websockets easily.
+* *(bridge)* Added retrying for appservice pings.
+* *(types)* Removed unstable field for MSC3952 (intentional mentions).
+* *(client)* Deprecated `OldEventIgnorer` and added `Client.DontProcessOldEvents`
+  to replace it.
+* *(client)* Added `MoveInviteState` sync handler for moving state events in
+  the invite section of sync inside the invite event itself.
+* *(crypto)* Added option to not rotate keys when devices change.
+* *(crypto)* Added additional duplicate message index check if decryption fails
+  because the keys had been ratcheted forward.
+* *(client)* Stabilized support for asynchronous uploads.
+  * `UnstableCreateMXC` and `UnstableUploadAsync` were renamed to `CreateMXC`
+    and `UploadAsync` respectively.
+* *(util/dbutil)* Added option to use a separate database connection pool for
+  read-only transactions.
+  * This is mostly meant for SQLite and it enables read-only transactions that
+    don't lock the database, even when normal transactions are configured to
+    acquire a write lock immediately.
+* *(util/dbutil)* Enabled caller info in zerolog by default.
+
+## v0.15.2 (2023-05-16)
+
+* *(client)* Changed member-fetching methods to clear existing member info in
+  state store.
+* *(client)* Added support for inserting mautrix-go commit hash into default
+  user agent at compile time.
+* *(bridge)* Fixed bridge bot intent not having state store set.
+* *(client)* Fixed `RespError` marshaling mutating the `ExtraData` map and
+  potentially causing panics.
+* *(util/dbutil)* Added `DoTxn` method for an easier way to manage database
+  transactions.
+* *(util)* Added a zerolog `CallerMarshalFunc` implementation that includes the
+  function name.
+* *(bridge)* Added error reply to encrypted messages if the bridge isn't
+  configured to do encryption.
+
+## v0.15.1 (2023-04-16)
+
+* *(crypto, bridge)* Added options to automatically ratchet/delete megolm
+  sessions to minimize access to old messages.
+* *(pushrules)* Added method to get entire push rule that matched (instead of
+  only the list of actions).
+* *(pushrules)* Deprecated `NotifySpecified` as there's no reason to read it.
+* *(crypto)* Changed `max_age` column in `crypto_megolm_inbound_session` table
+  to be milliseconds instead of nanoseconds.
+* *(util)* Added method for iterating `RingBuffer`.
+* *(crypto/cryptohelper)* Changed decryption errors to request session from all
+  own devices in addition to the sender, instead of only asking the sender.
+* *(sqlstatestore)* Fixed `FindSharedRooms` throwing an error when using from
+  a non-bridge context.
+* *(client)* Optimized `AccountDataSyncStore` to not resend save requests if
+  the sync token didn't change.
+* *(types)* Added `Clone()` method for `PowerLevelEventContent`.
+
+## v0.15.0 (2023-03-16)
+
+### beta.3 (2023-03-15)
+
+* **Breaking change *(appservice)*** Removed `Load()` and `AppService.Init()`
+  functions. The struct should just be created with `Create()` and the relevant
+  fields should be filled manually.
+* **Breaking change *(appservice)*** Removed public `HomeserverURL` field and
+  replaced it with a `SetHomeserverURL` method.
+* *(appservice)* Added support for unix sockets for homeserver URL and
+  appservice HTTP server.
+* *(client)* Changed request logging to log durations as floats instead of
+  strings (using zerolog's `Dur()`, so the exact output can be configured).
+* *(bridge)* Changed zerolog to use nanosecond precision timestamps.
+* *(crypto)* Added message index to log after encrypting/decrypting megolm
+  events, and when failing to decrypt due to duplicate index.
+* *(sqlstatestore)* Fixed warning log for rooms that don't have encryption
+  enabled.
+
+### beta.2 (2023-03-02)
+
+* *(bridge)* Fixed building with `nocrypto` tag.
+* *(bridge)* Fixed legacy logging config migration not disabling file writer
+  when `file_name_format` was empty.
+* *(bridge)* Added option to require room power level to run commands.
+* *(event)* Added structs for [MSC3952]: Intentional Mentions.
+* *(util/variationselector)* Added `FullyQualify` method to add necessary emoji
+  variation selectors without adding all possible ones.
+
+[MSC3952]: https://github.com/matrix-org/matrix-spec-proposals/pull/3952
+
+### beta.1 (2023-02-24)
+
+* Bumped minimum Go version to 1.19.
+* **Breaking changes**
+  * *(all)* Switched to zerolog for logging.
+    * The `Client` and `Bridge` structs still include a legacy logger for
+      backwards compatibility.
+  * *(client, appservice)* Moved `SQLStateStore` from appservice module to the
+    top-level (client) module.
+  * *(client, appservice)* Removed unused `Typing` map in `SQLStateStore`.
+  * *(client)* Removed unused `SaveRoom` and `LoadRoom` methods in `Storer`.
+  * *(client, appservice)* Removed deprecated `SendVideo` and `SendImage` methods.
+  * *(client)* Replaced `AppServiceUserID` field with `SetAppServiceUserID` boolean.
+    The `UserID` field is used as the value for the query param.
+  * *(crypto)* Renamed `GobStore` to `MemoryStore` and removed the file saving
+    features. The data can still be persisted, but the persistence part must be
+    implemented separately.
+  * *(crypto)* Removed deprecated `DeviceIdentity` alias
+    (renamed to `id.Device` long ago).
+  * *(client)* Removed `Stringifable` interface as it's the same as `fmt.Stringer`.
+* *(client)* Renamed `Storer` interface to `SyncStore`. A type alias exists for
+  backwards-compatibility.
+* *(crypto/cryptohelper)* Added package for a simplified crypto interface for clients.
+* *(example)* Added e2ee support to example using crypto helper.
+* *(client)* Changed default syncer to stop syncing on `M_UNKNOWN_TOKEN` errors.
+
+## v0.14.0 (2023-02-16)
+
+* **Breaking change *(format)*** Refactored the HTML parser `Context` to have
+  more data.
+* *(id)* Fixed escaping path components when forming matrix.to URLs
+  or `matrix:` URIs.
+* *(bridge)* Bumped default timeouts for decrypting incoming messages.
+* *(bridge)* Added `RawArgs` to commands to allow accessing non-split input.
+* *(bridge)* Added `ReplyAdvanced` to commands to allow setting markdown
+  settings.
+* *(event)* Added `notifications` key to `PowerLevelEventContent`.
+* *(event)* Changed `SetEdit` to cut off edit fallback if the message is long.
+* *(util)* Added `SyncMap` as a simple generic wrapper for a map with a mutex.
+* *(util)* Added `ReturnableOnce` as a wrapper for `sync.Once` with a return
+  value.
+
+## v0.13.0 (2023-01-16)
+
+* **Breaking change:** Removed `IsTyping` and `SetTyping` in `appservice.StateStore`
+  and removed the `TypingStateStore` struct implementing those methods.
+* **Breaking change:** Removed legacy fields in Beeper MSS events.
+* Added knocked rooms to sync response structs.
+* Added wrapper for `/timestamp_to_event` endpoint added in Matrix v1.6.
+* Fixed MSC3870 uploads not failing properly after using up the max retry count.
+* Fixed parsing non-positive ordered list start positions in HTML parser.
+
+## v0.12.4 (2022-12-16)
+
+* Added `SendReceipt` to support private read receipts and thread receipts in
+  the same function. `MarkReadWithContent` is now deprecated.
+* Changed media download methods to return errors if the server returns a
+  non-2xx status code.
+* Removed legacy `sql_store_upgrade.Upgrade` method. Using `store.DB.Upgrade()`
+  after `NewSQLCryptoStore(...)` is recommended instead (the bridge module does
+  this automatically).
+* Added missing `suggested` field to `m.space.child` content struct.
+* Added `device_unused_fallback_key_types` to `/sync` response and appservice
+  transaction structs.
+* Changed `ReqSetReadMarkers` to omit empty fields.
+* Changed bridge configs to force `sqlite3-fk-wal` instead of `sqlite3`.
+* Updated bridge helper to close database connection when stopping.
+* Fixed read receipt and account data endpoints sending `null` instead of an
+  empty object as the body when content isn't provided.
+
+## v0.12.3 (2022-11-16)
+
+* **Breaking change:** Added logging for row iteration in the dbutil package.
+  This changes the return type of `Query` methods from `*sql.Rows` to a new
+  `dbutil.Rows` interface.
+* Added flag to disable wrapping database upgrades in a transaction (e.g. to
+  allow setting `PRAGMA`s for advanced table mutations on SQLite).
+* Deprecated `MessageEventContent.GetReplyTo` in favor of directly using
+  `RelatesTo.GetReplyTo`. RelatesTo methods are nil-safe, so checking if
+  RelatesTo is nil is not necessary for using those methods.
+* Added wrapper for space hierarchyendpoint (thanks to [@mgcm] in [#100]).
+* Added bridge config option to handle transactions asynchronously.
+* Added separate channels for to-device events in appservice transaction
+  handler to avoid blocking to-device events behind normal events.
+* Added `RelatesTo.GetNonFallbackReplyTo` utility method to get the reply event
+  ID, unless the reply is a thread fallback.
+* Added `event.TextToHTML` as an utility method to HTML-escape a string and
+  replace newlines with `<br/>`.
+* Added check to bridge encryption helper to make sure the e2ee keys are still
+  on the server. Synapse is known to sometimes lose keys randomly.
+* Changed bridge crypto syncer to crash on `M_UNKNOWN_TOKEN` errors instead of
+  retrying forever pointlessly.
+* Fixed verifying signatures of fallback one-time keys.

+[#100]: https://github.com/mautrix/go/pull/100
+
+## v0.12.2 (2022-10-16)
+
+* Added utility method to redact bridge commands.
+* Added thread ID field to read receipts to match Matrix v1.4 changes.
+* Added automatic fetching of media repo config at bridge startup to make it
+  easier for bridges to check homeserver media size limits.
+* Added wrapper for the `/register/available` endpoint.
+* Added custom user agent to all requests mautrix-go makes. The value can be
+  customized by changing the `DefaultUserAgent` variable.
+* Implemented [MSC3664], [MSC3862] and [MSC3873] in the push rule evaluator.
+* Added workaround for potential race conditions in OTK uploads when using
+  appservice encryption ([MSC3202]).
+* Fixed generating registrations to use `.+` instead of `[0-9]+` in the
+  username regex.
+* Fixed panic in megolm session listing methods if the store contains withheld
+  key entries.
+* Fixed missing header in bridge command help messages.

+
+## v0.12.1 (2022-09-16)
+
+* Bumped minimum Go version to 1.18.
+* Added `omitempty` for a bunch of fields in response structs to make them more
+  usable for server implementations.
+* Added `util.RandomToken` to generate GitHub-style access tokens with checksums.
+* Added utilities to call the push gateway API.
+* Added `unread_notifications` and [MSC2654] `unread_count` fields to /sync
+  response structs.
+* Implemented [MSC3870] for uploading and downloading media directly to/from an
+  external media storage like S3.
+* Fixed dbutil database ownership checks on SQLite.
+* Fixed typo in unauthorized encryption key withheld code
+  (`m.unauthorized` -> `m.unauthorised`).
+* Fixed [MSC2409] support to have a separate field for to-device events.
+
+[MSC2654]: https://github.com/matrix-org/matrix-spec-proposals/pull/2654
+[MSC3870]: https://github.com/matrix-org/matrix-spec-proposals/pull/3870
+
+## v0.12.0 (2022-08-16)
+
+* **Breaking change:** Switched `Client.UserTyping` to take a `time.Duration`
+  instead of raw `int64` milliseconds.
+* **Breaking change:** Removed custom reply relation type and switched to using
+  the wire format (nesting in `m.in_reply_to`).
+* Added device ID to appservice OTK count map to match updated [MSC3202].
+  This is also a breaking change, but the previous incorrect behavior wasn't
+  implemented by anything other than mautrix-syncproxy/imessage.
+* (There are probably other breaking changes too).
+* Added database utility and schema upgrade framework
+  * Originally from mautrix-whatsapp, but usable for non-bridges too
+  * Includes connection wrapper to log query durations and mutate queries for
+    SQLite compatibility (replacing `$x` with `?x`).
+* Added bridge utilities similar to mautrix-python. Currently includes:
+  * Crypto helper
+  * Startup flow
+  * Command handling and some standard commands
+  * Double puppeting things
+  * Generic parts of config, basic config validation
+  * Appservice SQL state store
+* Added alternative markdown spoiler parsing extension that doesn't support
+  reasons, but works better otherwise.
+* Added Discord underline markdown parsing extension (`_foo_` -> <u>foo</u>).
+* Added support for parsing spoilers and color tags in the HTML parser.
+* Added support for mutating plain text nodes in the HTML parser.
+* Added room version field to the create room request struct.
+* Added empty JSON object as default request body for all non-GET requests.
+* Added wrapper for `/capabilities` endpoint.
+* Added `omitempty` markers for lots of structs to make the structs easier to
+  use on the server side too.
+* Added support for registering to-device event handlers via the default
+  Syncer's `OnEvent` and `OnEventType` methods.
+* Fixed `CreateEventContent` using the wrong field name for the room version
+  field.
+* Fixed `StopSync` not immediately cancelling the sync loop if it was sleeping
+  after a failed sync.
+* Fixed `GetAvatarURL` always returning the current user's avatar instead of
+  the specified user's avatar (thanks to [@nightmared] in [#83]).
+* Improved request logging and added new log when a request finishes.
+* Crypto store improvements:
+  * Deleted devices are now kept in the database.
+  * Made ValidateMessageIndex atomic.
+* Moved `appservice.RandomString` to the `util` package and made it use
+  `crypto/rand` instead of `math/rand`.
+* Significantly improved cross-signing validation code.
+  * There are now more options for required trust levels,
+    e.g. you can set `SendKeysMinTrust` to `id.TrustStateCrossSignedTOFU`
+    to trust the first cross-signing master key seen and require all devices
+    to be signed by that key.
+  * Trust state of incoming messages is automatically resolved and stored in
+    `evt.Mautrix.TrustState`. This can be used to reject incoming messages from
+    untrusted devices.

+## v0.11.1 (2023-01-15)
+
+* Fixed parsing non-positive ordered list start positions in HTML parser
+  (backport of the same fix in v0.13.0).
+
+## v0.11.0 (2022-05-16)
+
+* Bumped minimum Go version to 1.17.
+* Switched from `/r0` to `/v3` paths everywhere.
+  * The new `v3` paths are implemented since Synapse 1.48, Dendrite 0.6.5, and
+    Conduit 0.4.0. Servers older than these are no longer supported.
+* Switched from blackfriday to goldmark for markdown parsing in the `format`
+  module and added spoiler syntax.
+* Added `EncryptInPlace` and `DecryptInPlace` methods for attachment encryption.
+  In most cases the plain/ciphertext is not necessary after en/decryption, so
+  the old `Encrypt` and `Decrypt` are deprecated.
+* Added wrapper for `/rooms/.../aliases`.
+* Added utility for adding/removing emoji variation selectors to match
+  recommendations on reactions in Matrix.
+* Added support for async media uploads ([MSC2246]).
+* Added automatic sleep when receiving 429 error
+  (thanks to [@ownaginatious] in [#44]).
+* Added support for parsing spec version numbers from the `/versions` endpoint.
+* Removed unstable prefixed constant used for appservice login.
+* Fixed URL encoding not working correctly in some cases.

+
+## v0.10.12 (2022-03-16)
+
+* Added option to use a different `Client` to send invites in
+  `IntentAPI.EnsureJoined`.
+* Changed `MessageEventContent` struct to omit empty `msgtype`s in the output
+  JSON, as sticker events shouldn't have that field.
+* Fixed deserializing the `thumbnail_file` field in `FileInfo`.
+* Fixed bug that broke `SQLCryptoStore.FindDeviceByKey`.
+
+## v0.10.11 (2022-02-16)
+
+* Added automatic updating of state store from `IntentAPI` calls.
+* Added option to ignore cache in `IntentAPI.EnsureJoined`.
+* Added `GetURLPreview` as a wrapper for the `/preview_url` media repo endpoint.
+* Moved base58 module inline to avoid pulling in btcd as a dependency.
+
+## v0.10.10 (2022-01-16)
+
+* Added event types and content structs for server ACLs and moderation policy
+  lists (thanks to [@qua3k] in [#59] and [#60]).
+* Added optional parameter to `Client.LeaveRoom` to pass a `reason` field.
+

+
+## v0.10.9 (2022-01-04)
+
+* **Breaking change:** Changed `Messages()` to take a filter as a parameter
+  instead of using the syncer's filter (thanks to [@qua3k] in [#55] and [#56]).
+  * The previous filter behavior was completely broken, as it sent a whole
+    filter instead of just a RoomEventFilter.
+  * Passing `nil` as the filter is fine and will disable filtering
+    (which is equivalent to what it did before with the invalid filter).
+* Added `Context()` wrapper for the `/context` API (thanks to [@qua3k] in [#54]).
+* Added utility for converting media files with ffmpeg.

+## v0.10.8 (2021-12-30)
+
+* Added `OlmSession.Describe()` to wrap `olm_session_describe`.
+* Added trace logs to log olm session descriptions when encrypting/decrypting
+  to-device messages.
+* Added space event types and content structs.
+* Added support for power level content override field in `CreateRoom`.
+* Fixed ordering of olm sessions which would cause an old session to be used in
+  some cases even after a client created a new session.
+
+## v0.10.7 (2021-12-16)
+
+* Changed `Client.RedactEvent` to allow arbitrary fields in redaction request.
+
+## v0.10.5 (2021-12-06)
+
+* Fixed websocket disconnection not clearing all pending requests.
+* Added `OlmMachine.SendRoomKeyRequest` as a more direct way of sending room
+  key requests.
+* Added automatic Olm session recreation if an incoming message fails to decrypt.
+* Changed `Login` to only omit request content from logs if there's a password
+  or token (appservice logins don't have sensitive content).
+
+## v0.10.4 (2021-11-25)
+
+* Added `reason` field to invite and unban requests
+  (thanks to [@ptman] in [#48]).
+* Fixed `AppService.HasWebsocket()` returning `true` even after websocket has
+  disconnected.

+
+## v0.10.3 (2021-11-18)
+
+* Added logs about incoming appservice transactions.
+* Added support for message send checkpoints (as HTTP requests, similar to the
+  bridge state reporting system).
+
+## v0.10.2 (2021-11-15)
+
+* Added utility method for finding the first supported login flow matching any
+  of the given types.
+* Updated registering appservice ghosts to use `inhibit_login` flag to prevent
+  lots of unnecessary access tokens from being created.
+  * If you want to log in as an appservice ghost, you should use [MSC2778]'s
+    appservice login (e.g. like [mautrix-whatsapp does for e2be](https://github.com/mautrix/whatsapp/blob/v0.2.1/crypto.go#L143-L149)).
+
+## v0.10.1 (2021-11-05)
+
+* Removed direct dependency on `pq`
+  * In order to use some more efficient queries on postgres, you must set
+    `crypto.PostgresArrayWrapper = pq.Array` if you want to use both postgres
+    and e2ee.
+* Added temporary hack to ignore state events with the MSC2716 historical flag
+  (to be removed after [matrix-org/synapse#11265] is merged)
+* Added received transaction acknowledgements for websocket appservice
+  transactions.
+* Added automatic fallback to move `prev_content` from top level to the
+  standard location inside `unsigned`.

+* Added `SetEdit` utility function for `MessageEventContent`.
+
+## v0.9.30 (2021-10-26)
+
+* Added wrapper for [MSC2716]'s `/batch_send` endpoint.
+* Added `MarshalJSON` method for `Event` struct to prevent empty unsigned
+  structs from being included in the JSON.
+
+[MSC2716]: https://github.com/matrix-org/matrix-spec-proposals/pull/2716
+
+## v0.9.29 (2021-09-30)
+
+* Added `client.State` method to get full room state.
+* Added bridge info structs and event types ([MSC2346]).
+* Made response handling more customizable.
+* Fixed type of `AuthType` constants.
+
+[MSC2346]: https://github.com/matrix-org/matrix-spec-proposals/pull/2346
+
+## v0.9.28 (2021-09-30)
+
+* Added `X-Mautrix-Process-ID` to appservice websocket headers to help debug
+  issues where multiple instances are connecting to the server at the same time.
+
+## v0.9.27 (2021-09-23)
+
+* Fixed Go 1.14 compatibility (broken in v0.9.25).
+* Added GitHub actions CI to build, test and check formatting on Go 1.14-1.17.
+
+## v0.9.26 (2021-09-21)
+
+* Added default no-op logger to `Client` in order to prevent panic when the
+  application doesn't set a logger.
+
+## v0.9.25 (2021-09-19)
+
+* Disabled logging request JSON for sensitive requests like `/login`,
+  `/register` and other UIA endpoints. Logging can still be enabled by
+  setting `MAUTRIX_LOG_SENSITIVE_CONTENT` to `yes`.
+* Added option to store new homeserver URL from `/login` response well-known data.
+* Added option to stream big sync responses via disk to maybe reduce memory usage.
+* Fixed trailing slashes in homeserver URL breaking all requests.
+
+## v0.9.24 (2021-09-03)
+
+* Added write deadline for appservice websocket connection.
+
+## v0.9.23 (2021-08-31)
+
+* Fixed storing e2ee key withheld events in the SQL store.
+
+## v0.9.22 (2021-08-30)
+
+* Updated appservice handler to cache multiple recent transaction IDs
+  instead of only the most recent one.
+
+## v0.9.21 (2021-08-25)
+
+* Added liveness and readiness endpoints to appservices.
+  * The endpoints are the same as mautrix-python:
+    `/_matrix/mau/live` and `/_matrix/mau/ready`
+  * Liveness always returns 200 and an empty JSON object by default,
+    but it can be turned off by setting `appservice.Live` to `false`.
+  * Readiness defaults to returning 500, and it can be switched to 200
+    by setting `appservice.Ready` to `true`.
+
+## v0.9.20 (2021-08-19)
+
+* Added crypto store migration for converting all `VARCHAR(255)` columns
+  to `TEXT` in Postgres databases.
+
+## v0.9.19 (2021-08-17)
+
+* Fixed HTML parser outputting two newlines after paragraph tags.
+
+## v0.9.18 (2021-08-16)
+
+* Added new `BuildURL` method that does the same as `Client.BuildBaseURL`
+  but without requiring the `Client` instance.
+
+## v0.9.17 (2021-07-25)
+
+* Fixed handling OTK counts and device lists coming in through the appservice
+  transaction websocket.
+* Updated OlmMachine to ignore OTK counts intended for other devices.
+
+## v0.9.15 (2021-07-16)
+
+* Added support for [MSC3202] and the to-device part of [MSC2409] in the
+  appservice package.
+* Added support for sending commands through appservice websocket.
+* Changed error message JSON field name in appservice error responses to
+  conform with standard Matrix errors (`message` -> `error`).

+[MSC3202]: https://github.com/matrix-org/matrix-spec-proposals/pull/3202
+
+## v0.9.14 (2021-06-17)
+
+* Added default implementation of `PillConverter` in HTML parser utility.
+
+## v0.9.13 (2021-06-15)
+
+* Added support for parsing and generating encoded matrix.to URLs and `matrix:` URIs ([MSC2312](https://github.com/matrix-org/matrix-doc/pull/2312)).
+* Updated HTML parser to use new URI parser for parsing user/room pills.
+
+## v0.9.12 (2021-05-18)

+* Added VoIP events to GuessClass.
+* Added support for parsing strings in VoIP event version field.
+
+## v0.9.10 (2021-04-29)

+  and `allowMarkdown` are `false`.
+
+## v0.9.9 (2021-04-26)
+
+* Updated appservice `StartWebsocket` to return websocket close info.
+
+## v0.9.8 (2021-04-20)
+
+* Added methods for getting room tags and account data.
+
+## v0.9.7 (2021-04-19)
+
+* **Breaking change (crypto):** `SendEncryptedToDevice` now requires an event
+  type parameter. Previously it only allowed sending events of type
+  `event.ToDeviceForwardedRoomKey`.
+* Added content structs for VoIP events.
+* Added global mutex for Olm decryption
+  (previously it was only used for encryption).
+
+## v0.9.6 (2021-04-15)
+
+* Added option to retry all HTTP requests when encountering a HTTP network
+  error or gateway error response (502/503/504)
+  * Disabled by default, you need to set the `DefaultHTTPRetries` field in
+    the `AppService` or `Client` struct to enable.
+  * Can also be enabled with `FullRequest`s `MaxAttempts` field.
+
+## v0.9.5 (2021-04-06)
+
+* Reverted update of `golang.org/x/sys` which broke Go 1.14 / darwin/arm.
+
+## v0.9.4 (2021-04-06)
+
+* Switched appservices to using shared `http.Client` instance with a in-memory
+  cookie jar.
+
+## v0.9.3 (2021-03-26)
+
+* Made user agent headers easier to configure.
+* Improved logging when receiving weird/unhandled to-device events.
+
+## v0.9.2 (2021-03-15)
+
+* Fixed type of presence state constants (thanks to [@babolivier] in [#30]).
+* Implemented presence state fetching methods (thanks to [@babolivier] in [#29]).
+* Added support for sending and receiving commands via appservice transaction websocket.

+
+* Fixed appservice register request hiding actual errors due to UIA error handling.
+
+## v0.9.0 (2021-03-04)
+
+* **Breaking change (manual API requests):** `MakeFullRequest` now takes a
+  `FullRequest` struct instead of individual parameters. `MakeRequest`'s
+  parameters are unchanged.
+* **Breaking change (manual /sync):** `SyncRequest` now requires a `Context`
+  parameter.
+* **Breaking change (end-to-bridge encryption):**
+  the `uk.half-shot.msc2778.login.application_service` constant used for
+  appservice login ([MSC2778]) was renamed from `AuthTypeAppservice`
+  to `AuthTypeHalfyAppservice`.
+  * The `AuthTypeAppservice` constant now contains `m.login.application_service`,
+    which is currently only used for registrations, but will also be used for
+    login once MSC2778 lands in the spec.
+* Fixed appservice registration requests to include `m.login.application_service`
+  as the `type` (re [matrix-org/synapse#9548]).
+* Added wrapper for `/logout/all`.
