-# Synapse 1.120.2 (2024-12-03)
-
-This version has building of wheels for macOS disabled.
-It is functionally identical to 1.120.1, which contains multiple security fixes.
-If you are already using 1.120.1, there is no need to upgrade to this version.

-
-# Synapse 1.120.1 (2024-12-03)
-
-This patch release fixes multiple security vulnerabilities, some affecting all prior versions 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.
-
-Administrators who are unable to update Synapse may use the workarounds described in the linked GitHub Security Advisory below.
-
-### Security advisory
-
-The following issues are fixed in 1.120.1.
-
-- [GHSA-rfq8-j7rh-8hf2](https://github.com/element-hq/synapse/security/advisories/GHSA-rfq8-j7rh-8hf2) / [CVE-2024-52805](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-52805): **Unsupported content types can lead to memory exhaustion**
-
-  Synapse instances which have a high `max_upload_size` and which don't have a reverse proxy in front of them that would otherwise limit upload size are affected.
-
-  Fixed by [4b7154c58501b4bf5e1c2d6c11ebef96529f2fdf](https://github.com/element-hq/synapse/commit/4b7154c58501b4bf5e1c2d6c11ebef96529f2fdf).

-
-  Synapse instances can disable dynamic thumbnailing by setting `dynamic_thumbnails` to `false` in the configuration file.
-
-  Fixed by [b64a4e5fbbbf119b6c65aedf0d999b4237d55503](https://github.com/element-hq/synapse/commit/b64a4e5fbbbf119b6c65aedf0d999b4237d55503).

-
-  Non-state events, like messages, are unaffected.
-
-  Synapse instances can disable the Sliding Sync feature by setting `experimental_features.msc3575_enabled` to `false` in the configuration file.

-
-### Bugfixes
-
-- Fix release process to not create duplicate releases. ([\#17970](https://github.com/element-hq/synapse/issues/17970))
-
-
-
-# Synapse 1.120.0 (2024-11-26)
-
-### Bugfixes
-
-- Fix a bug introduced in Synapse v1.120rc1 which would cause the newly-introduced `delete_old_otks` job to fail in worker-mode deployments. ([\#17960](https://github.com/element-hq/synapse/issues/17960))
-
-
-
-
-# Synapse 1.120.0rc1 (2024-11-20)
-
-This release enables the enforcement of authenticated media by default, with exemptions for media that is already present in the
-homeserver's media store.
-
-Most homeservers operating in the public federation will not be impacted by this change, given that
-the large homeserver `matrix.org` enabled this in September 2024 and therefore most clients and servers
-will already have updated as a result.
-
-Some server administrators may still wish to disable this enforcement for the time being, in the interest of compatibility with older clients
-and older federated homeservers.
-See the [upgrade notes](https://element-hq.github.io/synapse/v1.120/upgrade.html#authenticated-media-is-now-enforced-by-default) for more information.
-
-### Features
-
-- Enforce authenticated media by default. Administrators can revert this by configuring `enable_authenticated_media` to `false`. In a future release of Synapse, this option will be removed and become always-on. ([\#17889](https://github.com/element-hq/synapse/issues/17889))
-- Add a one-off task to delete old One-Time Keys, to guard against us having old OTKs in the database that the client has long forgotten about. ([\#17934](https://github.com/element-hq/synapse/issues/17934))
-
-### Improved Documentation
-
-- Clarify the semantics of the `enable_authenticated_media` configuration option. ([\#17913](https://github.com/element-hq/synapse/issues/17913))
-- Add documentation about backing up Synapse. ([\#17931](https://github.com/element-hq/synapse/issues/17931))
-
-### Deprecations and Removals
-
-- Remove support for [MSC3886: Simple client rendezvous capability](https://github.com/matrix-org/matrix-spec-proposals/pull/3886), which has been superseded by [MSC4108](https://github.com/matrix-org/matrix-spec-proposals/pull/4108) and therefore closed. ([\#17638](https://github.com/element-hq/synapse/issues/17638))
-
-### Internal Changes
-
-- Addressed some typos in docs and returned error message for unknown MXC ID. ([\#17865](https://github.com/element-hq/synapse/issues/17865))
-- Unpin the upload release GHA action. ([\#17923](https://github.com/element-hq/synapse/issues/17923))

-## Redact all the events of a user
-
-This endpoint allows an admin to redact the events of a given user. There are no restrictions on redactions for a 
-local user. By default, we puppet the user who sent the message to redact it themselves. Redactions for non-local users are issued using the admin user, and will fail in rooms where the admin user is not admin/does not have the specified power level to issue redactions. 
-
-The API is 
-```
-POST /_synapse/admin/v1/user/$user_id/redact
-
-{
-  "rooms": ["!roomid1", "!roomid2"]
-}
-```
-If an empty list is provided as the key for `rooms`, all events in all the rooms the user is member of will be redacted, 
-otherwise all the events in the rooms provided in the request will be redacted. 
-
-The API starts redaction process running, and returns immediately with a JSON body with
-a redact id which can be used to query the status of the redaction process:
-
-```json
-{
-    "redact_id": "<opaque id>"
-}
-```
-
-**Parameters**
-
-The following parameters should be set in the URL:
-
-- `user_id` - The fully qualified MXID of the user: for example, `@user:server.com`.
-
-The following JSON body parameter must be provided:

--  `rooms` - A list of rooms to redact the user's events in. If an empty list is provided all events in all rooms
-  the user is a member of will be redacted
-
-_Added in Synapse 1.116.0._
-
-The following JSON body parameters are optional:
-
-- `reason` - Reason the redaction is being requested, ie "spam", "abuse", etc. This will be included in each redaction event, and be visible to users.
-- `limit` - a limit on the number of the user's events to search for ones that can be redacted (events are redacted newest to oldest) in each room, defaults to 1000 if not provided
-
-
-## Check the status of a redaction process
-
-It is possible to query the status of the background task for redacting a user's events.
-The status can be queried up to 24 hours after completion of the task,
-or until Synapse is restarted (whichever happens first).
-
-The API is:
-

-**Response**
-
-The following fields are returned in the JSON response body:
-
-- `status` - string - one of scheduled/active/completed/failed, indicating the status of the redaction job

-# How to back up a Synapse homeserver
-
-It is critical to maintain good backups of your server, to guard against
-hardware failure as well as potential corruption due to bugs or administrator
-error.
-
-This page documents the things you will need to consider backing up as part of
-a Synapse installation.
-
-## Configuration files
-
-Keep a copy of your configuration file (`homeserver.yaml`), as well as any
-auxiliary config files it refers to such as the
-[`log_config`](../configuration/config_documentation.md#log_config) file,
-[`app_service_config_files`](../configuration/config_documentation.md#app_service_config_files).
-Often, all such config files will be kept in a single directory such as
-`/etc/synapse`, which will make this easier.
-
-## Server signing key
-
-Your server has a [signing
-key](../configuration/config_documentation.md#signing_key_path) which it uses
-to sign events and outgoing federation requests. It is easiest to back it up
-with your configuration files, but an alternative is to have Synapse create a
-new signing key if you have to restore.
-
-If you do decide to replace the signing key, you should add the old *public*
-key to
-[`old_signing_keys`](../configuration/config_documentation.md#old_signing_keys).
-
-## Database
-
-Synapse's support for SQLite is only suitable for testing purposes, so for the
-purposes of this document, we'll assume you are using
-[PostgreSQL](../../postgres.md).
-
-A full discussion of backup strategies for PostgreSQL is out of scope for this
-document; see the [PostgreSQL
-documentation](https://www.postgresql.org/docs/current/backup.html) for
-detailed information.
-
-### Synapse-specfic details
-
- * Be very careful not to restore into a database that already has tables
-   present. At best, this will error; at worst, it will lead to subtle database
-   inconsistencies.
-
- * The `e2e_one_time_keys_json` table should **not** be backed up, or if it is
-   backed up, should be
-   [`TRUNCATE`d](https://www.postgresql.org/docs/current/sql-truncate.html)
-   after restoring the database before Synapse is started.
-
-   [Background: restoring the database to an older backup can cause
-   used one-time-keys to be re-issued, causing subsequent [message decryption
-   errors](https://github.com/element-hq/element-meta/issues/2155). Clearing
-   all one-time-keys from the database ensures that this cannot happen, and
-   will prompt clients to generate and upload new one-time-keys.]
-
-### Quick and easy database backup and restore
-
-Typically, the easiest solution is to use `pg_dump` to take a copy of the whole
-database. We recommend `pg_dump`'s custom dump format, as it produces
-significantly smaller backup files.
-
-```shell
-sudo -u postgres pg_dump -Fc --exclude-table-data e2e_one_time_keys_json synapse > synapse.dump
-```
-
-There is no need to stop Postgres or Synapse while `pg_dump` is running: it
-will take a consistent snapshot of the databse.
-
-To restore, you will need to recreate the database as described in [Using
-Postgres](../../postgres.md#set-up-database),
-then load the dump into it with `pg_restore`:
-
-```shell
-sudo -u postgres createdb --encoding=UTF8 --locale=C --template=template0 --owner=synapse_user synapse
-sudo -u postgres pg_restore -d synapse < synapse.dump
-```
-
-(If you forgot to exclude `e2e_one_time_keys_json` during `pg_dump`, remember
-to connect to the new database and `TRUNCATE e2e_one_time_keys_json;` before
-starting Synapse.)
-
-To reiterate: do **not** restore a dump over an existing database.
-
-Again, if you plan to run your homeserver at any sort of production level, we
-recommend studying the PostgreSQL documentation on backup options.
-
-## Media store
-
-Synapse keeps a copy of media uploaded by users, including avatars and message
-attachments, in its [Media
-store](../configuration/config_documentation.md#media-store).
-
-It is a directory on the local disk, containing the following directories:
-
- * `local_content`: this is content uploaded by your local users. As a general
-   rule, you should back this up: it may represent the only copy of those
-   media files anywhere in the federation, and if they are lost, users will
-   see errors when viewing user or room avatars, and messages with attachments.
-
- * `local_thumbnails`: "thumbnails" of images uploaded by your users. If
-   [`dynamic_thumbnails`](../configuration/config_documentation.md#dynamic_thumbnails)
-   is enabled, these will be regenerated if they are removed from the disk, and
-   there is therefore no need to back them up.
-
-   If `dynamic_thumbnails` is *not* enabled (the default): although this can
-   theoretically be regenerated from `local_content`, there is no tooling to do
-   so. We recommend that these are backed up too.
-
- * `remote_content`: this is a cache of content that was uploaded by a user on
-    another server, and has since been requested by a user on your own server.
-
-    Typically there is no need to back up this directory: if a file in this directory
-    is removed, Synapse will attempt to fetch it again from the remote
-    server.
-
- * `remote_thumbnails`: thumbnails of images uploaded by users on other
-    servers. As with `remote_content`, there is normally no need to back this
-    up.
-
- * `url_cache`, `url_cache_thumbnails`: temporary caches of files downloaded
-   by the [URL previews](../../setup/installation.md#url-previews) feature.
-   These do not need to be backed up.

 When set to true, all subsequent media uploads will be marked as authenticated, and will not be available over legacy
 unauthenticated media endpoints (`/_matrix/media/(r0|v3|v1)/download` and `/_matrix/media/(r0|v3|v1)/thumbnail`) - requests for authenticated media over these endpoints will result in a 404. All media, including authenticated media, will be available over the authenticated media endpoints `_matrix/client/v1/media/download` and `_matrix/client/v1/media/thumbnail`. Media uploaded prior to setting this option to true will still be available over the legacy endpoints. Note if the setting is switched to false
-after enabling, media marked as authenticated will be available over legacy endpoints. Defaults to true (previously false). In a future release of Synapse, this option will be removed and become always-on.
-
-In all cases, authenticated requests to download media will succeed, but for unauthenticated requests, this
-case-by-case breakdown describes whether media downloads are permitted:
-
-* `enable_authenticated_media = False`:
-  * unauthenticated client or homeserver requesting local media: allowed
-  * unauthenticated client or homeserver requesting remote media: allowed as long as the media is in the cache,
-    or as long as the remote homeserver does not require authentication to retrieve the media
-* `enable_authenticated_media = True`:
-  * unauthenticated client or homeserver requesting local media:
-    allowed if the media was stored on the server whilst `enable_authenticated_media` was `False` (or in a previous Synapse version where this option did not exist);
-    otherwise denied.
-  * unauthenticated client or homeserver requesting remote media: the same as for local media;
-    allowed if the media was stored on the server whilst `enable_authenticated_media` was `False` (or in a previous Synapse version where this option did not exist);
-    otherwise denied.
-
-It is especially notable that media downloaded before this option existed (in older Synapse versions), or whilst this option was set to `False`,
-will perpetually be available over the legacy, unauthenticated endpoint, even after this option is set to `True`.
-This is for backwards compatibility with older clients and homeservers that do not yet support requesting authenticated media;
-those older clients or homeservers will not be cut off from media they can already see.
