+## 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.
+
+[MSC3664]: https://github.com/matrix-org/matrix-spec-proposals/pull/3664
+[MSC3862]: https://github.com/matrix-org/matrix-spec-proposals/pull/3862
+[MSC3873]: https://github.com/matrix-org/matrix-spec-proposals/pull/3873
+
+## 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.

+[#44]: https://github.com/mautrix/go/pull/44
+
+## 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.
+
+[#59]: https://github.com/mautrix/go/pull/59
+[#60]: https://github.com/mautrix/go/pull/60
+
+## 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.

+[@qua3k]: https://github.com/qua3k
+
+## 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.
+
+[@ptman]: https://github.com/ptman
+[#48]: https://github.com/mautrix/go/pull/48
+
+## 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`.
+
+[matrix-org/synapse#11265]: https://github.com/matrix-org/synapse/pull/11265
+
+## v0.9.31 (2021-10-27)
+
+* 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 new method for sending custom data with read receipts
+  (not currently a part of the spec).
+
+## v0.9.11 (2021-05-12)
+
+* Improved debug log for unsupported event types.
+* Added VoIP events to GuessClass.
+* Added support for parsing strings in VoIP event version field.
+
+## v0.9.10 (2021-04-29)
+
+* Fixed `format.RenderMarkdown()` still allowing HTML when both `allowHTML`
+  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.

+
+## v0.9.1 (2021-03-11)
+
+* 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`.

+[matrix-org/synapse#9548]: https://github.com/matrix-org/synapse/pull/9548
+
+## v0.8.6 (2021-03-02)
+
+* Added client-side timeout to `mautrix.Client`'s `http.Client`
+  (defaults to 3 minutes).
+* Updated maulogger to fix bug where plaintext file logs wouldn't have newlines.
+
+## v0.8.5 (2021-02-26)
+
+* Fixed potential concurrent map writes in appservice `Client` and `Intent`
+  methods.
+
+## v0.8.4 (2021-02-24)
+
+* Added option to output appservice logs as JSON.
+* Added new methods for validating user ID localparts.
+
+## v0.8.3 (2021-02-21)
+
+* Allowed empty content URIs in parser
+* Added functions for device management endpoints
+  (thanks to [@edwargix] in [#26]).
+
+[@edwargix]: https://github.com/edwargix
+[#26]: https://github.com/mautrix/go/pull/26
+
+## v0.8.2 (2021-02-09)
+
+* Fixed error when removing the user's avatar.
+
+## v0.8.1 (2021-02-09)
+
+* Added AccountDataStore to remove the need for persistent local storage other
+  than the access token (thanks to [@daenney] in [#23]).
+* Added support for receiving appservice transactions over websocket.
+  See <https://github.com/mautrix/wsproxy> for the server-side implementation.
+* Fixed error when removing the room avatar.
+
+[@daenney]: https://github.com/daenney
+[#23]: https://github.com/mautrix/go/pull/23
+
+## v0.8.0 (2020-12-24)
+
+* **Breaking change:** the `RateLimited` field in the `Registration` struct is
+  now a pointer, so that it can be omitted entirely.
+* Merged initial SSSS/cross-signing code by [@nikofil]. Interactive verification
+  doesn't work, but the other things mostly do.
+* Added support for authorization header auth in appservices ([MSC2832]).
+* Added support for receiving ephemeral events directly ([MSC2409]).
+* Fixed `SendReaction()` and other similar methods in the `Client` struct.
+* Fixed crypto cgo code panicking in Go 1.15.3+.
+* Fixed olm session locks sometime getting deadlocked.

+2. License Grants and Conditions
+--------------------------------
+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or

+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+*  Covered Software is provided under this License on an "as is"       *
+*  basis, without warranty of any kind, either expressed, implied, or  *
+*  statutory, including, without limitation, warranties that the       *
+*  Covered Software is free of defects, merchantable, fit for a        *
+*  particular purpose or non-infringing. The entire risk as to the     *
+*  quality and performance of the Covered Software is with You.        *
+*  Should any Covered Software prove defective in any respect, You     *
+*  (not any Contributor) assume the cost of any necessary servicing,   *
+*  repair, or correction. This disclaimer of warranty constitutes an   *
+*  essential part of this License. No use of any Covered Software is   *
+*  authorized under this License except under this disclaimer.         *
+*                                                                      *

+*  Under no circumstances and under no legal theory, whether tort      *
+*  (including negligence), contract, or otherwise, shall any           *
+*  Contributor, or anyone who distributes Covered Software as          *
+*  permitted above, be liable to You for any direct, indirect,         *

+*  including, without limitation, damages for lost profits, loss of    *
+*  goodwill, work stoppage, computer failure or malfunction, or any    *

+************************************************************************
+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or

+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a
+modified version of this License if you rename the license and remove

+# String globbing in Go
+
+[![GoDoc](https://godoc.org/github.com/zyedidia/glob?status.svg)](http://godoc.org/github.com/zyedidia/glob)
+
+This package adds support for globs in Go.
+
+It simply converts glob expressions to regexps. I try to follow the standard defined [here](http://pubs.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_13).
+
+# Example
+
+```go
+package main
+
+import "github.com/zyedidia/glob"
+
+func main() {
+    glob, err := glob.Compile("{*.go,*.c}")
+    if err != nil {
+        // Error
+    }
+
+    glob.Match([]byte("test.c"))   // true
+    glob.Match([]byte("hello.go")) // true
+    glob.Match([]byte("test.d"))   // false
+}
+```
+
+You can call all the same functions on a glob that you can call on a regexp.

+/*
+Package base58 provides an API for working with modified base58 and Base58Check
+encodings.
+
+# Modified Base58 Encoding
+
+Standard base58 encoding is similar to standard base64 encoding except, as the
+name implies, it uses a 58 character alphabet which results in an alphanumeric
+string and allows some characters which are problematic for humans to be
+excluded.  Due to this, there can be various base58 alphabets.
+
+The modified base58 alphabet used by Bitcoin, and hence this package, omits the
+0, O, I, and l characters that look the same in many fonts and are therefore
+hard to humans to distinguish.
+
+# Base58Check Encoding Scheme
+
+The Base58Check encoding scheme is primarily used for Bitcoin addresses at the
+time of this writing, however it can be used to generically encode arbitrary
+byte arrays into human-readable strings along with a version byte that can be
+used to differentiate the same payload.  For Bitcoin addresses, the extra
+version is used to differentiate the network of otherwise identical public keys
+which helps prevent using an address intended for one network on another.
+*/
