Subject: [PATCH 020/304] Standardise content type handling in MSC3089
 createFile() and createNewVersion() (#2014)

* Provide cross platform compatible versions of createFile() and createNewVersion()

The exist implementations are deprecated as they only work in a browser and support a different type of contents from MatrixClient.uploadContent()

* Fix MSC3089 content upload meta data in NodeJS runtime

* Break unstable createFile() and createNewVersion() instead of deprecating

Test using NodeJS types instead of mocked browser Blob

* chore: remove incorrect comment

+Changes in [15.2.0-rc.1](https://github.com/matrix-org/matrix-js-sdk/releases/tag/v15.2.0-rc.1) (2021-11-30)
+============================================================================================================
+
+## ✨ Features
+ * Remove support for `ArrayBuffer` in unstable MSC3089 `createFile()` and `createNewVersion()` and instead use same content types as handled by `MatrixClient.uploadContent()`. This enables support for Node.js. ([\#2014](https://github.com/matrix-org/matrix-js-sdk/pull/2014)).
+ * Support for password-based backup on Node.js ([\#2021](https://github.com/matrix-org/matrix-js-sdk/pull/2021)).
+ * Add optional force parameter when ensuring Olm sessions ([\#2027](https://github.com/matrix-org/matrix-js-sdk/pull/2027)).
+
+## 🐛 Bug Fixes

+Changes in [15.2.0](https://github.com/matrix-org/matrix-js-sdk/releases/tag/v15.2.0) (2021-12-06)
+==================================================================================================
+
+## ✨ Features
+ * Remove support for `ArrayBuffer` in unstable MSC3089 `createFile()` and `createNewVersion()` and instead use same content types as handled by `MatrixClient.uploadContent()`. This enables support for Node.js. ([\#2014](https://github.com/matrix-org/matrix-js-sdk/pull/2014)).
+ * Support for password-based backup on Node.js ([\#2021](https://github.com/matrix-org/matrix-js-sdk/pull/2021)).
+ * Add optional force parameter when ensuring Olm sessions ([\#2027](https://github.com/matrix-org/matrix-js-sdk/pull/2027)).
+
+## 🐛 Bug Fixes
+ * Fix call upgrades ([\#2024](https://github.com/matrix-org/matrix-js-sdk/pull/2024)). Contributed by @SimonBrandner.

+Changes in [15.4.0-rc.1](https://github.com/matrix-org/matrix-js-sdk/releases/tag/v15.4.0-rc.1) (2022-01-11)
+============================================================================================================
+
+## ✨ Features
+ * Don't consider alt_aliases when calculating room name ([\#2094](https://github.com/matrix-org/matrix-js-sdk/pull/2094)). Fixes vector-im/element-web#13887.
+ * Load room history if necessary when searching for MSC3089 getFileEvent() ([\#2066](https://github.com/matrix-org/matrix-js-sdk/pull/2066)).
+ * Add support for MSC3030 `/timestamp_to_event` ([\#2072](https://github.com/matrix-org/matrix-js-sdk/pull/2072)).
+
+## 🐛 Bug Fixes
+ * Stop encrypting redactions as it isn't spec compliant ([\#2098](https://github.com/matrix-org/matrix-js-sdk/pull/2098)). Fixes vector-im/element-web#20460.
+ * Fix more function typings relating to key backup ([\#2086](https://github.com/matrix-org/matrix-js-sdk/pull/2086)).
+ * Fix timeline search in MSC3089 getFileEvent() ([\#2085](https://github.com/matrix-org/matrix-js-sdk/pull/2085)).
+ * Set a `deviceId` for VoIP example and use `const`/`let` ([\#2090](https://github.com/matrix-org/matrix-js-sdk/pull/2090)). Fixes #2083. Contributed by @SimonBrandner.
+ * Fix incorrect TS return type for secret storage and key backup functions ([\#2082](https://github.com/matrix-org/matrix-js-sdk/pull/2082)).
+

+==================================================================================================
+
+## ✨ Features
+ * Don't consider alt_aliases when calculating room name ([\#2094](https://github.com/matrix-org/matrix-js-sdk/pull/2094)). Fixes vector-im/element-web#13887.
+ * Load room history if necessary when searching for MSC3089 getFileEvent() ([\#2066](https://github.com/matrix-org/matrix-js-sdk/pull/2066)).
+ * Add support for MSC3030 `/timestamp_to_event` ([\#2072](https://github.com/matrix-org/matrix-js-sdk/pull/2072)).
+
+## 🐛 Bug Fixes
+ * Stop encrypting redactions as it isn't spec compliant ([\#2098](https://github.com/matrix-org/matrix-js-sdk/pull/2098)). Fixes vector-im/element-web#20460.
+ * Fix more function typings relating to key backup ([\#2086](https://github.com/matrix-org/matrix-js-sdk/pull/2086)).
+ * Fix timeline search in MSC3089 getFileEvent() ([\#2085](https://github.com/matrix-org/matrix-js-sdk/pull/2085)).
+ * Set a `deviceId` for VoIP example and use `const`/`let` ([\#2090](https://github.com/matrix-org/matrix-js-sdk/pull/2090)). Fixes #2083. Contributed by @SimonBrandner.
+ * Fix incorrect TS return type for secret storage and key backup functions ([\#2082](https://github.com/matrix-org/matrix-js-sdk/pull/2082)).

Subject: [PATCH 090/304] Move polls to events-sdk, and invent a
 RelatedRelations type (#2102)

* Move polls handling to events-sdk & invent a multi-relation handler

Polls are now fully handled by the events-sdk instead of by the js-sdk.

The multi-relation handler (RelatedRelations) is primarily meant to handle unstable & stable support in polls when it becomes stable.

* update events-sdk for polls

* Update events-sdk for polls bugfix

* Update events-sdk for maintenance

The 'Replaced' error code is handled specially (for better or worse)
so was leaving the capture feeds open. Use the 'transfer' hangup
reason which is what we should be using anyway (and were, on the line

Subject: [PATCH 152/304] Fix bug where calls could break if rejected from
 somewhere else (#2189)

* Fix bug where calls could ignore new events of rejected from somewhere else

When callEventHandler passed a reject event to the call object, it assumed
that always caused the call to end and deleted it from the list, so it
never got any more events. The point of a reject is that it doesn't
end the call if it's already been picked up though. This only removes
the call if it's actually ended.

* Use ts-expect-error

Subject: [PATCH 158/304] Fix bug with ine-way audio after a transfer (#2193)

Seems chrome at least will give you a disabled audio track if you
already had another user media audio track and disabled it, so make
sure our tracks are enabled when we add them. We already did this
on one code path but it didn't get moved over when a new code path
was added.

+/**
+ * Beacon info events are state events.
+ * We have two requirements for these events:
+ * 1. they can only be written by their owner
+ * 2. a user can have an arbitrary number of beacon_info events
+ *
+ * 1. is achieved by setting the state_key to the owners mxid.
+ * Event keys in room state are a combination of `type` + `state_key`.
+ * To achieve an arbitrary number of only owner-writable state events
+ * we introduce a variable suffix to the event type
+ *
+ * Eg
+ * {
+ *      "type": "m.beacon_info.@matthew:matrix.org.1",
+ *      "state_key": "@matthew:matrix.org",
+ *      "content": {
+ *          "m.beacon_info": {
+ *              "description": "The Matthew Tracker",
+ *              "timeout": 86400000,
+ *          },
+ *          // more content as described below
+ *      }
+ * },
+ * {
+ *      "type": "m.beacon_info.@matthew:matrix.org.2",
+ *      "state_key": "@matthew:matrix.org",
+ *      "content": {
+ *          "m.beacon_info": {
+ *              "description": "Another different Matthew tracker",

+Changes in [16.0.0](https://github.com/matrix-org/matrix-js-sdk/releases/tag/v16.0.0) (2022-03-15)
+==================================================================================================
+
+## 🚨 BREAKING CHANGES
+ * Improve typing around event emitter handlers ([\#2180](https://github.com/matrix-org/matrix-js-sdk/pull/2180)).
+
+## ✨ Features
+ * Fix defer not supporting resolving with a Promise<T> ([\#2216](https://github.com/matrix-org/matrix-js-sdk/pull/2216)).
+ * add LocationAssetType enum ([\#2214](https://github.com/matrix-org/matrix-js-sdk/pull/2214)).
+ * Support for mid-call devices changes ([\#2154](https://github.com/matrix-org/matrix-js-sdk/pull/2154)). Contributed by @SimonBrandner.
+ * Add new room state emit RoomStateEvent.Update for lower-frequency hits ([\#2192](https://github.com/matrix-org/matrix-js-sdk/pull/2192)).
+
+## 🐛 Bug Fixes
+ * Fix wrong event_id being sent for m.in_reply_to of threads ([\#2213](https://github.com/matrix-org/matrix-js-sdk/pull/2213)).
+ * Fix wrongly asserting that PushRule::conditions is non-null ([\#2217](https://github.com/matrix-org/matrix-js-sdk/pull/2217)).
+ * Make createThread more resilient when missing rootEvent ([\#2207](https://github.com/matrix-org/matrix-js-sdk/pull/2207)). Fixes vector-im/element-web#21130.
+ * Fix bug with the /hierarchy API sending invalid requests ([\#2201](https://github.com/matrix-org/matrix-js-sdk/pull/2201)). Fixes vector-im/element-web#21170.
+ * fix relation sender filter ([\#2196](https://github.com/matrix-org/matrix-js-sdk/pull/2196)). Fixes vector-im/element-web#20877.
+ * Fix bug with one-way audio after a transfer ([\#2193](https://github.com/matrix-org/matrix-js-sdk/pull/2193)).

 Tests
 -----
-If your PR is a feature (ie. if it's being labelled with the 'T-Enhancement'
-label) then we require that the PR also includes tests. These need to test that
-your feature works as expected and ideally test edge cases too. For the js-sdk
-itself, your tests should generally be unit tests. matrix-react-sdk also uses
-these guidelines, so for that your tests can be unit tests using
-react-test-utils, snapshot tests or screenshot tests.
+Your PR should include tests.
 
-We don't require tests for bug fixes (T-Defect) but strongly encourage regression
-tests for the bug itself wherever possible.
+For new user facing features in `matrix-react-sdk` or `element-web`, you
+must include:
 
-In the future we may formalise this more with a minimum test coverage
-percentage for the diff.
+1. Comprehensive unit tests written in Jest. These are located in `/test`.
+2. "happy path" end-to-end tests.
+   These are located in `/test/end-to-end-tests` in `matrix-react-sdk`, and
+   are run using `element-web`. Ideally, you would also include tests for edge
+   and error cases.
+
+Unit tests are expected even when the feature is in labs. It's good practice
+to write tests alongside the code as it ensures the code is testable from
+the start, and gives you a fast feedback loop while you're developing the
+functionality. End-to-end tests should be added prior to the feature
+leaving labs, but don't have to be present from the start (although it might
+be beneficial to have some running early, so you can test things faster).
+
+For bugs in those repos, your change must include at least one unit test or
+end-to-end test; which is best depends on what sort of test most concisely
+exercises the area.
+
+Changes to `matrix-js-sdk` must be accompanied by unit tests written in Jest.
+These are located in `/spec/`.
+
+When writing unit tests, please aim for a high level of test coverage
+for new code - 80% or greater. If you cannot achieve that, please document
+why it's not possible in your PR.
+
+Tests validate that your change works as intended and also document
+concisely what is being changed. Ideally, your new tests fail
+prior to your change, and succeed once it has been applied. You may
+find this simpler to achieve if you write the tests first.
+
+If you're spiking some code that's experimental and not being used to support
+production features, exceptions can be made to requirements for tests.
+Note that tests will still be required in order to ship the feature, and it's
+strongly encouraged to think about tests early in the process, as adding
+tests later will become progressively more difficult.
+
+If you're not sure how to approach writing tests for your change, ask for help
+in [#element-dev](https://matrix.to/#/#element-dev:matrix.org).

Subject: [PATCH 220/304] Remove groups (#2234)

This API is due for removal in Synapse and has been deprecated for a very long time. People should move away from it soon, but just in case we'll declare this as a breaking change.

There is no impact on sync storage here: we happen to store the data in a way that is backwards-compatible for group-supporting clients, and the code guards against missing data from the stores. So, if someone were to revert, they'd be "safe" (probably lose all their group info, but the app wouldn't crash).

From: Callum Brown <callum@calcuode.com>
Date: Sat, 9 Apr 2022 05:53:57 +0100
Subject: [PATCH 249/304] Stabilise token authenticated registration support
 (#2181)

* Stabilise token authenticated registration support

Token authenticated registration was added to the Matrix specification in v1.2:
https://spec.matrix.org/v1.2/client-server-api/#token-authenticated-registration

Signed-off-by: Callum Brown <callum@calcuode.com>

* Backwards compatibility with unstable auth type

Servers are not yet widely updated with support for the stable
version of the registration token UIA type.
Clients should check if the authentication type is either
`RegistrationToken` or `UnstableRegistrationToken`.

+## ✨ Features
+ * Add MatrixClient.doesServerSupportLogoutDevices() for MSC2457 ([\#2297](https://github.com/matrix-org/matrix-js-sdk/pull/2297)).
+ * Live location sharing - expose room liveBeaconIds ([\#2296](https://github.com/matrix-org/matrix-js-sdk/pull/2296)).
+ * Support for MSC2457 logout_devices param for setPassword() ([\#2285](https://github.com/matrix-org/matrix-js-sdk/pull/2285)).
+ * Stabilise token authenticated registration support ([\#2181](https://github.com/matrix-org/matrix-js-sdk/pull/2181)). Contributed by @govynnus.
+ * Live location sharing - Aggregate beacon locations on beacons ([\#2268](https://github.com/matrix-org/matrix-js-sdk/pull/2268)).
+
+## 🐛 Bug Fixes
+ * Prevent duplicated re-emitter setups in event-mapper ([\#2293](https://github.com/matrix-org/matrix-js-sdk/pull/2293)).
+ * Make self membership less prone to races ([\#2277](https://github.com/matrix-org/matrix-js-sdk/pull/2277)). Fixes vector-im/element-web#21661.

+==============
+
+The preferred method for merging pull requests is squash merging to keep the
+commit history trim, but it is up to the discretion of the team member merging
+the change. When stacking pull requests, you may wish to do the following:
+
+1. Branch from develop to your branch (branch1), push commits onto it and open a pull request
+2. Branch from your base branch (branch1) to your work branch (branch2), push commits and open a pull request configuring the base to be branch1, saying in the description that it is based on your other PR.
+3. Merge the first PR using a merge commit otherwise your stacked PR will need a rebase. Github will automatically adjust the base branch of your other PR to be develop.
