-### 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Simple client rendezvous capability](https://github.com/matrix-org/matrix-spec-proposals/pull/3886), which has been superseded by [MSC4108](https://github.com/matrix-org/matrix-spec-proposals/pull/4108) and therefore closed.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))
-- Bump macOS version used to build wheels during release, as current version used is end-of-life. ([\#17924](https://github.com/element-hq/synapse/issues/17924))
-- Move server event filtering logic to Rust. ([\#17928](https://github.com/element-hq/synapse/issues/17928))
-- Support new package name of PyPI package `python-multipart` 0.0.13 so that distro packagers do not need to work around name conflict with PyPI package `multipart`. ([\#17932](https://github.com/element-hq/synapse/issues/17932))
-- Speed up slow initial sliding syncs on large servers. ([\#17946](https://github.com/element-hq/synapse/issues/17946))

([\#17915](https://github.com/element-hq/synapse/pull/17915))
-
-### Internal Changes
-
-- Remove support for python 3.8. ([\#17908](https://github.com/element-hq/synapse/issues/17908))

 ## Worker Service Examples in Docker Compose
 
 In order to start the Synapse container as a worker, you must specify an `entrypoint` that loads both the `homeserver.yaml` and the configuration for the worker (`synapse-generic-worker-1.yaml` in the example below). You must also include the worker type in the environment variable `SYNAPSE_WORKER` or alternatively pass `-m synapse.app.generic_worker` as part of the `entrypoint` after `"/start.py", "run"`).

-## Authenticated media is now enforced by default
-
-The [`enable_authenticated_media`] configuration option now defaults to true.
-
-This means that clients and remote (federated) homeservers now need to use
-the authenticated media endpoints in order to download media from your
-homeserver.
-
-As an exception, existing media that was stored on the server prior to
-this option changing to `true` will still be accessible over the
-unauthenticated endpoints.
-
-The matrix.org homeserver has already been running with this option enabled
-since September 2024, so most common clients and homeservers should already
-be compatible.
-
-With that said, administrators who wish to disable this feature for broader
-compatibility can still do so by manually configuring

-# 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.

+        # This leads to a lot of CPU load, and we end up getting behind. The solution
+        # currently adopted is as follows:
         #
-        # The current logic is to send receipts out immediately if:
-        #   - the room is "small", i.e. there's only N servers to send receipts
-        #     to, and so sending out the receipts immediately doesn't cause too
-        #     much load; or
-        #   - the receipt is for an event that happened recently, as users
-        #     notice if receipts are delayed when they know other users are
-        #     currently reading the room; or
-        #   - the receipt is being sent to the server that sent the event, so
-        #     that users see receipts for their own receipts quickly.
+        # The first receipt in a given room is sent out immediately, at time T0. Any
+        # further receipts are, in theory, batched up for N seconds, where N is calculated
+        # based on the number of servers in the room to achieve a transaction frequency
+        # of around 50Hz. So, for example, if there were 100 servers in the room, then
+        # N would be 100 / 50Hz = 2 seconds.
         #
-        # For destinations that we should delay sending the receipt to, we queue
-        # the receipts up to be sent in the next transaction, but don't trigger
-        # a new transaction to be sent. We then add the destination to the
-        # `DestinationWakeupQueue`, which will slowly iterate over each
-        # destination and trigger a new transaction to be sent.
+        # Then, after T+N, we flush out any receipts that have accumulated, and restart
+        # the timer to flush out more receipts at T+2N, etc. If no receipts accumulate,
+        # we stop the cycle and go back to the start.
         #
-        # However, in practice, it is often possible to send out delayed
-        # receipts earlier: in particular, if we are sending a transaction to a
-        # given server anyway (for example, because we have a PDU or a RR in
-        # another room to send), then we may as well send out all of the pending
-        # RRs for that server. So it may be that by the time we get to waking up
-        # the destination, we don't actually have any RRs left to send out.
