+Deprecation Policy for Platform Dependencies
+============================================
+
+Synapse has a number of platform dependencies, including Python and PostgreSQL.
+This document outlines the policy towards which versions we support, and when we
+drop support for versions in the future.
+
+
+Policy
+------
+
+Synapse follows the upstream support life cycles for Python and PostgreSQL,
+i.e. when a version reaches End of Life Synapse will withdraw support for that
+version in future releases.
+
+Details on the upstream support life cycles for Python and PostgreSQL are
+documented at https://endoflife.date/python and
+https://endoflife.date/postgresql.
+
+
+Context
+-------
+
+It is important for system admins to have a clear understanding of the platform
+requirements of Synapse and its deprecation policies so that they can
+effectively plan upgrading their infrastructure ahead of time. This is
+especially important in contexts where upgrading the infrastructure requires
+auditing and approval from a security team, or where otherwise upgrading is a
+long process.
+
+By following the upstream support life cycles Synapse can ensure that its
+dependencies continue to get security patches, while not requiring system admins
+to constantly update their platform dependencies to the latest versions.

+# Presence Router Module
+
+Synapse supports configuring a module that can specify additional users
+(local or remote) to should receive certain presence updates from local
+users.
+
+Note that routing presence via Application Service transactions is not
+currently supported.
+
+The presence routing module is implemented as a Python class, which will
+be imported by the running Synapse.
+
+## Python Presence Router Class
+
+The Python class is instantiated with two objects:
+
+* A configuration object of some type (see below).
+* An instance of `synapse.module_api.ModuleApi`.
+
+It then implements methods related to presence routing.
+
+Note that one method of `ModuleApi` that may be useful is:
+
+```python
+async def ModuleApi.send_local_online_presence_to(users: Iterable[str]) -> None
+```
+
+which can be given a list of local or remote MXIDs to broadcast known, online user
+presence to (for those users that the receiving user is considered interested in). 
+It does not include state for users who are currently offline, and it can only be
+called on workers that support sending federation.
+
+### Module structure
+
+Below is a list of possible methods that can be implemented, and whether they are
+required.
+
+#### `parse_config`
+
+```python
+def parse_config(config_dict: dict) -> Any
+```
+
+**Required.** A static method that is passed a dictionary of config options, and
+  should return a validated config object. This method is described further in
+  [Configuration](#configuration).
+
+#### `get_users_for_states`
+
+```python
+async def get_users_for_states(
+    self,
+    state_updates: Iterable[UserPresenceState],
+) -> Dict[str, Set[UserPresenceState]]:
+```
+
+**Required.** An asynchronous method that is passed an iterable of user presence
+state. This method can determine whether a given presence update should be sent to certain
+users. It does this by returning a dictionary with keys representing local or remote
+Matrix User IDs, and values being a python set
+of `synapse.handlers.presence.UserPresenceState` instances.
+
+Synapse will then attempt to send the specified presence updates to each user when
+possible.
+
+#### `get_interested_users`
+
+```python
+async def get_interested_users(self, user_id: str) -> Union[Set[str], str]
+```
+
+**Required.** An asynchronous method that is passed a single Matrix User ID. This
+method is expected to return the users that the passed in user may be interested in the
+presence of. Returned users may be local or remote. The presence routed as a result of
+what this method returns is sent in addition to the updates already sent between users
+that share a room together. Presence updates are deduplicated.
+
+This method should return a python set of Matrix User IDs, or the object
+`synapse.events.presence_router.PresenceRouter.ALL_USERS` to indicate that the passed
+user should receive presence information for *all* known users.
+
+For clarity, if the user `@alice:example.org` is passed to this method, and the Set
+`{"@bob:example.com", "@charlie:somewhere.org"}` is returned, this signifies that Alice
+should receive presence updates sent by Bob and Charlie, regardless of whether these
+users share a room.
+
+### Example
+
+Below is an example implementation of a presence router class.
+
+```python
+from typing import Dict, Iterable, Set, Union
+from synapse.events.presence_router import PresenceRouter
+from synapse.handlers.presence import UserPresenceState

+            return PresenceRouter.ALL_USERS
+
+        return set()
+```
+
+#### A note on `get_users_for_states` and `get_interested_users`
+
+Both of these methods are effectively two different sides of the same coin. The logic
+regarding which users should receive updates for other users should be the same 
+between them.
+
+`get_users_for_states` is called when presence updates come in from either federation 
+or local users, and is used to either direct local presence to remote users, or to
+wake up the sync streams of local users to collect remote presence.
+
+In contrast, `get_interested_users` is used to determine the users that presence should
+be fetched for when a local user is syncing. This presence is then retrieved, before
+being fed through `get_users_for_states` once again, with only the syncing user's
+routing information pulled from the resulting dictionary.
+
+Their routing logic should thus line up, else you may run into unintended behaviour.
+
+## Configuration
+
+Once you've crafted your module and installed it into the same Python environment as
+Synapse, amend your homeserver config file with the following.
+
+```yaml
+presence:
+  routing_module:
+    module: my_module.ExamplePresenceRouter
+    config:
+      # Any configuration options for your module. The below is an example.
+      # of setting options for ExamplePresenceRouter.
+      always_send_to_users: ["@presence_gobbler:example.org"]
+      blacklisted_users:
+        - "@alice:example.com"
+        - "@bob:example.com"
+      ...
+```
+
+The contents of `config` will be passed as a Python dictionary to the static
+`parse_config` method of your class. The object returned by this method will
+then be passed to the `__init__` method of your module as `config`.
