-Synapse 1.81.0 (2023-04-11)
-===========================
-
-Synapse now attempts the versioned appservice paths before falling back to the
-[legacy paths](https://spec.matrix.org/v1.6/application-service-api/#legacy-routes).
-Usage of the legacy routes should be considered deprecated.
-
-Additionally, Synapse has supported sending the application service access token
-via [the `Authorization` header](https://spec.matrix.org/v1.6/application-service-api/#authorization)
-since v1.70.0. For backwards compatibility it is *also* sent as the `access_token`
-query parameter. This is insecure and should be considered deprecated.
-
-A future version of Synapse (v1.88.0 or later) will remove support for legacy
-application service routes and query parameter authorization.
-
-
-No significant changes since 1.81.0rc2.

-## Caching
-
-_Added in Synapse 1.74.0._
-
-Modules can leverage Synapse's caching tools to manage their own cached functions. This
-can be helpful for modules that need to repeatedly request the same data from the database
-or a remote service.
-
-Functions that need to be wrapped with a cache need to be decorated with a `@cached()`
-decorator (which can be imported from `synapse.module_api`) and registered with the
-[`ModuleApi.register_cached_function`](https://github.com/matrix-org/synapse/blob/release-v1.77/synapse/module_api/__init__.py#L888)
-API when initialising the module. If the module needs to invalidate an entry in a cache,
-it needs to use the [`ModuleApi.invalidate_cache`](https://github.com/matrix-org/synapse/blob/release-v1.77/synapse/module_api/__init__.py#L904)
-API, with the function to invalidate the cache of and the key(s) of the entry to
-invalidate.
-
-Below is an example of a simple module using a cached function:
-
-```python
-from typing import Any
-from synapse.module_api import cached, ModuleApi
-
-class MyModule:
-    def __init__(self, config: Any, api: ModuleApi):
-        self.api = api
-        
-        # Register the cached function so Synapse knows how to correctly invalidate

-        
-        # Get the user. Since get_department_for_user is wrapped with a cache,
-        # the return value for this user_id will be cached.
-        department = await self.get_department_for_user(user_id)

-        # Do something with `department`...
-

-        # them in the cache is out of date, so we want to invalidate it.

-"third-party rules" Synapse module callback method in favour of a new module method,
-[`on_add_user_third_party_identifier`](modules/third_party_rules_callbacks.md#on_add_user_third_party_identifier).
-`on_threepid_bind` will be removed in a future version of Synapse. You should check whether any Synapse
-modules in use in your deployment are making use of `on_threepid_bind`, and update them where possible.
-
-The arguments and functionality of the new method are the same.
-
-The justification behind the name change is that the old method's name, `on_threepid_bind`, was
-misleading. A user is considered to "bind" their third-party ID to their Matrix ID only if they
-do so via an [identity server](https://spec.matrix.org/latest/identity-service-api/)
-(so that users on other homeservers may find them). But this method was not called in that case -
-it was only called when a user added a third-party identifier on the local homeserver.

-"""
-The Federation Sender is responsible for sending Persistent Data Units (PDUs)
-and Ephemeral Data Units (EDUs) to other homeservers using
-the `/send` Federation API.
-
-
-## How do PDUs get sent?
-
-The Federation Sender is made aware of new PDUs due to `FederationSender.notify_new_events`.
-When the sender is notified about a newly-persisted PDU that originates from this homeserver
-and is not an out-of-band event, we pass the PDU to the `_PerDestinationQueue` for each
-remote homeserver that is in the room at that point in the DAG.
-
-
-### Per-Destination Queues
-
-There is one `PerDestinationQueue` per 'destination' homeserver.
-The `PerDestinationQueue` maintains the following information about the destination:
-
-- whether the destination is currently in [catch-up mode (see below)](#catch-up-mode);
-- a queue of PDUs to be sent to the destination; and
-- a queue of EDUs to be sent to the destination (not considered in this section).
-
-Upon a new PDU being enqueued, `attempt_new_transaction` is called to start a new
-transaction if there is not already one in progress.
-
-
-### Transactions and the Transaction Transmission Loop
-
-Each federation HTTP request to the `/send` endpoint is referred to as a 'transaction'.
-The body of the HTTP request contains a list of PDUs and EDUs to send to the destination.
-
-The *Transaction Transmission Loop* (`_transaction_transmission_loop`) is responsible
-for emptying the queued PDUs (and EDUs) from a `PerDestinationQueue` by sending
-them to the destination.
-
-There can only be one transaction in flight for a given destination at any time.
-(Other than preventing us from overloading the destination, this also makes it easier to
-reason about because we process events sequentially for each destination.
-This is useful for *Catch-Up Mode*, described later.)
-
-The loop continues so long as there is anything to send. At each iteration of the loop, we:
-
-- dequeue up to 50 PDUs (and up to 100 EDUs).
-- make the `/send` request to the destination homeserver with the dequeued PDUs and EDUs.
-- if successful, make note of the fact that we succeeded in transmitting PDUs up to
-  the given `stream_ordering` of the latest PDU by
-- if unsuccessful, back off from the remote homeserver for some time.
-  If we have been unsuccessful for too long (when the backoff interval grows to exceed 1 hour),
-  the in-memory queues are emptied and we enter [*Catch-Up Mode*, described below](#catch-up-mode).
-
-
-### Catch-Up Mode
-
-When the `PerDestinationQueue` has the catch-up flag set, the *Catch-Up Transmission Loop*
-(`_catch_up_transmission_loop`) is used in lieu of the regular `_transaction_transmission_loop`.
-(Only once the catch-up mode has been exited can the regular tranaction transmission behaviour
-be resumed.)
-
-*Catch-Up Mode*, entered upon Synapse startup or once a homeserver has fallen behind due to
-connection problems, is responsible for sending PDUs that have been missed by the destination
-homeserver. (PDUs can be missed because the `PerDestinationQueue` is volatile — i.e. resets
-on startup — and it does not hold PDUs forever if `/send` requests to the destination fail.)
-
-The catch-up mechanism makes use of the `last_successful_stream_ordering` column in the
-`destinations` table (which gives the `stream_ordering` of the most recent successfully
-sent PDU) and the `stream_ordering` column in the `destination_rooms` table (which gives,
-for each room, the `stream_ordering` of the most recent PDU that needs to be sent to this
-destination).
-
-Each iteration of the loop pulls out 50 `destination_rooms` entries with the oldest
-`stream_ordering`s that are greater than the `last_successful_stream_ordering`.
-In other words, from the set of latest PDUs in each room to be sent to the destination,
-the 50 oldest such PDUs are pulled out.
-
-These PDUs could, in principle, now be directly sent to the destination. However, as an
-optimisation intended to prevent overloading destination homeservers, we instead attempt
-to send the latest forward extremities so long as the destination homeserver is still
-eligible to receive those.
-This reduces load on the destination **in aggregate** because all Synapse homeservers
-will behave according to this principle and therefore avoid sending lots of different PDUs
-at different points in the DAG to a recovering homeserver.
-*This optimisation is not currently valid in rooms which are partial-state on this homeserver,
-since we are unable to determine whether the destination homeserver is eligible to receive
-the latest forward extremities unless this homeserver sent those PDUs — in this case, we
-just send the latest PDUs originating from this server and skip this optimisation.*
-
-Whilst PDUs are sent through this mechanism, the position of `last_successful_stream_ordering`
-is advanced as normal.
-Once there are no longer any rooms containing outstanding PDUs to be sent to the destination
-*that are not already in the `PerDestinationQueue` because they arrived since Catch-Up Mode
-was enabled*, Catch-Up Mode is exited and we return to `_transaction_transmission_loop`.
-
-
-#### A note on failures and back-offs
-
-If a remote server is unreachable over federation, we back off from that server,
-with an exponentially-increasing retry interval.
-Whilst we don't automatically retry after the interval, we prevent making new attempts
-until such time as the back-off has cleared.
-Once the back-off is cleared and a new PDU or EDU arrives for transmission, the transmission
-loop resumes and empties the queue by making federation requests.
-
-If the backoff grows too large (> 1 hour), the in-memory queue is emptied (to prevent
-unbounded growth) and Catch-Up Mode is entered.
-
-It is worth noting that the back-off for a remote server is cleared once an inbound
-request from that remote server is received (see `notify_remote_server_up`).
-At this point, the transaction transmission loop is also started up, to proactively
-send missed PDUs and EDUs to the destination (i.e. you don't need to wait for a new PDU
-or EDU, destined for that destination, to be created in order to send out missed PDUs and
-EDUs).
