-directory. This documentation is intended primarily for sysadmins running their
-own Synapse instance, as well as developers interacting externally with
-Synapse. [docs/dev](docs/dev) exists primarily to house documentation for
-Synapse developers. [docs/admin_api](docs/admin_api) houses documentation
-regarding Synapse's Admin API, which is used mostly by sysadmins and external
-service developers.

-New files added to both folders should be written in [Github-Flavoured
-Markdown](https://guides.github.com/features/mastering-markdown/), and attempts
-should be made to migrate existing documents to markdown where possible.

-Upgrading to v1.26.0
-====================
-
-Rolling back to v1.25.0 after a failed upgrade
-----------------------------------------------
-
-v1.26.0 includes a lot of large changes. If something problematic occurs, you
-may want to roll-back to a previous version of Synapse. Because v1.26.0 also
-includes a new database schema version, reverting that version is also required
-alongside the generic rollback instructions mentioned above. In short, to roll
-back to v1.25.0 you need to:
-
-1. Stop the server
-2. Decrease the schema version in the database:
-
-   .. code:: sql
-
-      UPDATE schema_version SET version = 58;
-
-3. Delete the ignored users & chain cover data:
-
-   .. code:: sql
-
-      DROP TABLE IF EXISTS ignored_users;
-      UPDATE rooms SET has_auth_chain_index = false;
-
-   For PostgreSQL run:
-
-   .. code:: sql
-
-      TRUNCATE event_auth_chain_links;
-      TRUNCATE event_auth_chains;
-
-   For SQLite run:
-
-   .. code:: sql
-
-      DELETE FROM event_auth_chain_links;
-      DELETE FROM event_auth_chains;
-
-4. Mark the deltas as not run (so they will re-run on upgrade).
-
-   .. code:: sql
-
-      DELETE FROM applied_schema_deltas WHERE version = 59 AND file = "59/01ignored_user.py";
-      DELETE FROM applied_schema_deltas WHERE version = 59 AND file = "59/06chain_cover_index.sql";
-
-5. Downgrade Synapse by following the instructions for your installation method
-   in the "Rolling back to older versions" section above.
-
-Upgrading to v1.25.0
-====================
-
-Last release supporting Python 3.5
-----------------------------------
-
-This is the last release of Synapse which guarantees support with Python 3.5,
-which passed its upstream End of Life date several months ago.
-
-We will attempt to maintain support through March 2021, but without guarantees.
-
-In the future, Synapse will follow upstream schedules for ending support of
-older versions of Python and PostgreSQL. Please upgrade to at least Python 3.6
-and PostgreSQL 9.6 as soon as possible.
-
-Blacklisting IP ranges
-----------------------
-
-Synapse v1.25.0 includes new settings, ``ip_range_blacklist`` and
-``ip_range_whitelist``, for controlling outgoing requests from Synapse for federation,
-identity servers, push, and for checking key validity for third-party invite events.
-The previous setting, ``federation_ip_range_blacklist``, is deprecated. The new
-``ip_range_blacklist`` defaults to private IP ranges if it is not defined.
-
-If you have never customised ``federation_ip_range_blacklist`` it is recommended
-that you remove that setting.
-
-If you have customised ``federation_ip_range_blacklist`` you should update the
-setting name to ``ip_range_blacklist``.
-
-If you have a custom push server that is reached via private IP space you may
-need to customise ``ip_range_blacklist`` or ``ip_range_whitelist``.
-
-Upgrading to v1.24.0
-====================
-
-Custom OpenID Connect mapping provider breaking change
-------------------------------------------------------
-
-This release allows the OpenID Connect mapping provider to perform normalisation
-of the localpart of the Matrix ID. This allows for the mapping provider to
-specify different algorithms, instead of the [default way](https://matrix.org/docs/spec/appendices#mapping-from-other-character-sets).
-
-If your Synapse configuration uses a custom mapping provider
-(`oidc_config.user_mapping_provider.module` is specified and not equal to
-`synapse.handlers.oidc_handler.JinjaOidcMappingProvider`) then you *must* ensure
-that `map_user_attributes` of the mapping provider performs some normalisation
-of the `localpart` returned. To match previous behaviour you can use the
-`map_username_to_mxid_localpart` function provided by Synapse. An example is
-shown below:
-
-.. code-block:: python
-
-  from synapse.types import map_username_to_mxid_localpart
-
-  class MyMappingProvider:
-      def map_user_attributes(self, userinfo, token):
-          # ... your custom logic ...
-          sso_user_id = ...
-          localpart = map_username_to_mxid_localpart(sso_user_id)
-
-          return {"localpart": localpart}
-
-Removal historical Synapse Admin API 
-------------------------------------
-
-Historically, the Synapse Admin API has been accessible under:
-
-* ``/_matrix/client/api/v1/admin``
-* ``/_matrix/client/unstable/admin``
-* ``/_matrix/client/r0/admin``
-* ``/_synapse/admin/v1``
-
-The endpoints with ``/_matrix/client/*`` prefixes have been removed as of v1.24.0.
-The Admin API is now only accessible under:
-
-* ``/_synapse/admin/v1``
-
-The only exception is the `/admin/whois` endpoint, which is
-`also available via the client-server API <https://matrix.org/docs/spec/client_server/r0.6.1#get-matrix-client-r0-admin-whois-userid>`_.
-
-The deprecation of the old endpoints was announced with Synapse 1.20.0 (released
-on 2020-09-22) and makes it easier for homeserver admins to lock down external
-access to the Admin API endpoints.
-
-Upgrading to v1.23.0
-====================
-
-Structured logging configuration breaking changes
--------------------------------------------------
-
-This release deprecates use of the ``structured: true`` logging configuration for
-structured logging. If your logging configuration contains ``structured: true``
-then it should be modified based on the `structured logging documentation
-<https://github.com/matrix-org/synapse/blob/master/docs/structured_logging.md>`_.
-
-The ``structured`` and ``drains`` logging options are now deprecated and should
-be replaced by standard logging configuration of ``handlers`` and ``formatters``.
-
-A future will release of Synapse will make using ``structured: true`` an error.
-
