-Synapse 1.49.0 (2021-12-14)
-===========================
-
-No significant changes since version 1.49.0rc1.
-
-
-Support for Ubuntu 21.04 ends next month on the 20th of January
----------------------------------------------------------------
-
-For users of Ubuntu 21.04 (Hirsute Hippo), please be aware that [upstream support for this version of Ubuntu will end next month][Ubuntu2104EOL].
-We will stop producing packages for Ubuntu 21.04 after upstream support ends.
-
-[Ubuntu2104EOL]: https://lists.ubuntu.com/archives/ubuntu-announce/2021-December/000275.html
-
-
-The wiki has been migrated to the documentation website
--------------------------------------------------------
-
-We've decided to move the existing, somewhat stagnant pages from the GitHub wiki
-to the [documentation website](https://matrix-org.github.io/synapse/latest/).
-
-This was done for two reasons. The first was to ensure that changes are checked by
-multiple authors before being committed (everyone makes mistakes!) and the second
-was visibility of the documentation. Not everyone knows that Synapse has some very
-useful information hidden away in its GitHub wiki pages. Bringing them to the
-documentation website should help with visibility, as well as keep all Synapse documentation
-in one, easily-searchable location.
-
-Note that contributions to the documentation website happen through [GitHub pull
-requests](https://github.com/matrix-org/synapse/pulls). Please visit [#synapse-dev:matrix.org](https://matrix.to/#/#synapse-dev:matrix.org)
-if you need help with the process!

-Synapse 1.49.0rc1 (2021-12-07)
-==============================
-
-Features
---------
-
-- Add [MSC3030](https://github.com/matrix-org/matrix-doc/pull/3030) experimental client and federation API endpoints to get the closest event to a given timestamp. ([\#9445](https://github.com/matrix-org/synapse/issues/9445))
-- Include bundled relation aggregations during a limited `/sync` request and `/relations` request, per [MSC2675](https://github.com/matrix-org/matrix-doc/pull/2675). ([\#11284](https://github.com/matrix-org/synapse/issues/11284), [\#11478](https://github.com/matrix-org/synapse/issues/11478))
-- Add plugin support for controlling database background updates. ([\#11306](https://github.com/matrix-org/synapse/issues/11306), [\#11475](https://github.com/matrix-org/synapse/issues/11475), [\#11479](https://github.com/matrix-org/synapse/issues/11479))
-- Support the stable API endpoints for [MSC2946](https://github.com/matrix-org/matrix-doc/pull/2946): the room `/hierarchy` endpoint. ([\#11329](https://github.com/matrix-org/synapse/issues/11329))
-- Add admin API to get some information about federation status with remote servers. ([\#11407](https://github.com/matrix-org/synapse/issues/11407))
-- Support expiry of refresh tokens and expiry of the overall session when refresh tokens are in use. ([\#11425](https://github.com/matrix-org/synapse/issues/11425))
-- Stabilise support for [MSC2918](https://github.com/matrix-org/matrix-doc/blob/main/proposals/2918-refreshtokens.md#msc2918-refresh-tokens) refresh tokens as they have now been merged into the Matrix specification. ([\#11435](https://github.com/matrix-org/synapse/issues/11435), [\#11522](https://github.com/matrix-org/synapse/issues/11522))
-- Update [MSC2918 refresh token](https://github.com/matrix-org/matrix-doc/blob/main/proposals/2918-refreshtokens.md#msc2918-refresh-tokens) support to confirm with the latest revision: accept the `refresh_tokens` parameter in the request body rather than in the URL parameters. ([\#11430](https://github.com/matrix-org/synapse/issues/11430))
-- Support configuring the lifetime of non-refreshable access tokens separately to refreshable access tokens. ([\#11445](https://github.com/matrix-org/synapse/issues/11445))
-- Expose `synapse_homeserver` and `synapse_worker` commands as entry points to run Synapse's main process and worker processes, respectively. Contributed by @Ma27. ([\#11449](https://github.com/matrix-org/synapse/issues/11449))
-- `synctl stop` will now wait for Synapse to exit before returning. ([\#11459](https://github.com/matrix-org/synapse/issues/11459), [\#11490](https://github.com/matrix-org/synapse/issues/11490))
-- Extend the "delete room" admin api to work correctly on rooms which have previously been partially deleted. ([\#11523](https://github.com/matrix-org/synapse/issues/11523))
-- Add support for the `/_matrix/client/v3/login/sso/redirect/{idpId}` API from Matrix v1.1. This endpoint was overlooked when support for v3 endpoints was added in Synapse 1.48.0rc1. ([\#11451](https://github.com/matrix-org/synapse/issues/11451))
-
-
-Bugfixes
---------
-
-- Fix using [MSC2716](https://github.com/matrix-org/matrix-doc/pull/2716) batch sending in combination with event persistence workers. Contributed by @tulir at Beeper. ([\#11220](https://github.com/matrix-org/synapse/issues/11220))
-- Fix a long-standing bug where all requests that read events from the database could get stuck as a result of losing the database connection, properly this time. Also fix a race condition introduced in the previous insufficient fix in Synapse 1.47.0. ([\#11376](https://github.com/matrix-org/synapse/issues/11376))
-- The `/send_join` response now includes the stable `event` field instead of the unstable field from [MSC3083](https://github.com/matrix-org/matrix-doc/pull/3083). ([\#11413](https://github.com/matrix-org/synapse/issues/11413))
-- Fix a bug introduced in Synapse 1.47.0 where `send_join` could fail due to an outdated `ijson` version. ([\#11439](https://github.com/matrix-org/synapse/issues/11439), [\#11441](https://github.com/matrix-org/synapse/issues/11441), [\#11460](https://github.com/matrix-org/synapse/issues/11460))
-- Fix a bug introduced in Synapse 1.36.0 which could cause problems fetching event-signing keys from trusted key servers. ([\#11440](https://github.com/matrix-org/synapse/issues/11440))
-- Fix a bug introduced in Synapse 1.47.1 where the media repository would fail to work if the media store path contained any symbolic links. ([\#11446](https://github.com/matrix-org/synapse/issues/11446))
-- Fix an `LruCache` corruption bug, introduced in Synapse 1.38.0, that would cause certain requests to fail until the next Synapse restart. ([\#11454](https://github.com/matrix-org/synapse/issues/11454))
-- Fix a long-standing bug where invites from ignored users were included in incremental syncs. ([\#11511](https://github.com/matrix-org/synapse/issues/11511))
-- Fix a regression in Synapse 1.48.0 where presence workers would not clear their presence updates over replication on shutdown. ([\#11518](https://github.com/matrix-org/synapse/issues/11518))
-- Fix a regression in Synapse 1.48.0 where the module API's `looping_background_call` method would spam errors to the logs when given a non-async function. ([\#11524](https://github.com/matrix-org/synapse/issues/11524))
-
-
-Updates to the Docker image
----------------------------
-

-
-
-Internal Changes
-----------------

-Synapse 1.47.1 (2021-11-23)
-===========================
-
-This release fixes a security issue in the media store, affecting all prior releases of Synapse. Server administrators are encouraged to update Synapse as soon as possible. We are not aware of these vulnerabilities being exploited in the wild.
-
-Server administrators who are unable to update Synapse may use the workarounds described in the linked GitHub Security Advisory below.
-
-Security advisory
------------------
-
-The following issue is fixed in 1.47.1.
-
-- **[GHSA-3hfw-x7gx-437c](https://github.com/matrix-org/synapse/security/advisories/GHSA-3hfw-x7gx-437c) / [CVE-2021-41281](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-41281): Path traversal when downloading remote media.**
-
-  Synapse instances with the media repository enabled can be tricked into downloading a file from a remote server into an arbitrary directory, potentially outside the media store directory.
-
-  The last two directories and file name of the path are chosen randomly by Synapse and cannot be controlled by an attacker, which limits the impact.
-
-  Homeservers with the media repository disabled are unaffected. Homeservers configured with a federation whitelist are also unaffected.
-
-  Fixed by [91f2bd090](https://github.com/matrix-org/synapse/commit/91f2bd090).

+This is no longer necessary. If you are using a reverse proxy for all of your

-Invoking `trial` as above will use an in-memory SQLite database. This is great for

-in production (and indeed, we have some code paths specific to each database).
-This means that we need to run our unit tests against PostgreSQL too. Our CI does
-this automatically for pull requests and release candidates, but it's sometimes
-useful to reproduce this locally.
-
-To do so, [configure Postgres](../postgres.md) and run `trial` with the

-
-- `SYNAPSE_POSTGRES` to anything nonempty
-- `SYNAPSE_POSTGRES_HOST`
-- `SYNAPSE_POSTGRES_USER`
-- `SYNAPSE_POSTGRES_PASSWORD`
-
-For example:
-
-```shell
-export SYNAPSE_POSTGRES=1
-export SYNAPSE_POSTGRES_HOST=localhost
-export SYNAPSE_POSTGRES_USER=postgres
-export SYNAPSE_POSTGRES_PASSWORD=mydevenvpassword
-trial
-```

-#### Prebuilt container
-
-Since configuring PostgreSQL can be fiddly, we can make use of a pre-made
-Docker container to set up PostgreSQL and run our tests for us. To do so, run
-
-```shell
-scripts-dev/test_postgresql.sh
-```
-
-Any extra arguments to the script will be passed to `tox` and then to `trial`,
-so we can run a specific test in this container with e.g.
-
-```shell
-scripts-dev/test_postgresql.sh tests.replication.test_sharded_event_persister.EventPersisterShardTestCase
-```
-
-The container creates a folder in your Synapse checkout called
-`.tox-pg-container` and uses this as a tox environment. The output of any
-`trial` runs goes into `_trial_temp` in your synapse source directory — the same
-as running `trial` directly on your host machine.

-# Implementing experimental features in Synapse
-
-It can be desirable to implement "experimental" features which are disabled by
-default and must be explicitly enabled via the Synapse configuration. This is
-applicable for features which:
-
-* Are unstable in the Matrix spec (e.g. those defined by an MSC that has not yet been merged).
-* Developers are not confident in their use by general Synapse administrators/users
-  (e.g. a feature is incomplete, buggy, performs poorly, or needs further testing).
-
-Note that this only really applies to features which are expected to be desirable
-to a broad audience. The [module infrastructure](../modules/index.md) should
-instead be investigated for non-standard features.
-
-Guarding experimental features behind configuration flags should help with some
-of the following scenarios:
-
-* Ensure that clients do not assume that unstable features exist (failing
-  gracefully if they do not).
-* Unstable features do not become de-facto standards and can be removed
-  aggressively (since only those who have opted-in will be affected).
-* Ease finding the implementation of unstable features in Synapse (for future
-  removal or stabilization).
-* Ease testing a feature (or removal of feature) due to enabling/disabling without
-  code changes. It also becomes possible to ask for wider testing, if desired.
-
-Experimental configuration flags should be disabled by default (requiring Synapse
-administrators to explicitly opt-in), although there are situations where it makes
-sense (from a product point-of-view) to enable features by default. This is
-expected and not an issue.
-
-It is not a requirement for experimental features to be behind a configuration flag,
-but one should be used if unsure.
-
-New experimental configuration flags should be added under the `experimental`
-configuration key (see the `synapse.config.experimental` file) and either explain
-(briefly) what is being enabled, or include the MSC number.
