+# Synapse 1.142.0 (2025-11-11)
+
+## Dropped support for Python 3.9
+
+This release drops support for Python 3.9, in line with our [dependency
+deprecation
+policy](https://element-hq.github.io/synapse/latest/deprecation_policy.html#platform-dependencies),
+as it is now [end of life](https://endoflife.date/python).
+
+## SQLite 3.40.0+ is now required
+
+The minimum supported SQLite version has been increased from 3.27.0 to 3.40.0.
+
+If you use current versions of the
+[matrixorg/synapse](setup/installation.html#docker-images-and-ansible-playbooks)
+Docker images, no action is required.
+
+
+## Deprecation of MacOS Python wheels
+
+The team has decided to deprecate and eventually stop publishing python wheels
+for MacOS. This is a burden on the team, and we're not aware of any parties
+that use them. Synapse docker images will continue to work on MacOS, as will
+building Synapse from source (though note this requires a Rust compiler).
+
+At present, publishing MacOS Python wheels will continue for the next release
+(1.143.0), but will not be available after that (1.144.0+). If you do make use
+of these wheels downstream, please reach out to us in
+[#synapse-dev:matrix.org](https://matrix.to/#/#synapse-dev:matrix.org). We'd
+love to hear from you!
+
+## Internal Changes
+
+- Properly stop building wheels for Python 3.9 and free-threaded CPython. ([\#19154](https://github.com/element-hq/synapse/issues/19154))
+
+
+
+
+# Synapse 1.142.0rc4 (2025-11-07)
+
+## Bugfixes
+
+- Fix a bug introduced in 1.142.0rc1 where any attempt to configure `matrix_authentication_service.secret_path` would prevent the homeserver from starting up. ([\#19144](https://github.com/element-hq/synapse/issues/19144))
+
+
+
+
+# Synapse 1.142.0rc3 (2025-11-04)
+
+## Internal Changes
+
+- Update release scripts to prevent building wheels for free-threaded Python, as Synapse does not currently support it. ([\#19140](https://github.com/element-hq/synapse/issues/19140))
+
+
+# Synapse 1.142.0rc2 (2025-11-04)
+
+
+## Internal Changes

+- Update the `oidc_session_no_samesite` cookie to have the `Secure` attribute, so the only difference between it and the paired `oidc_session` cookie, is the configuration of the `SameSite` attribute as described in the comments / cookie names. Contributed by @kieranlane. ([\#19079](https://github.com/element-hq/synapse/issues/19079))
+- Fix a bug introduced in 1.140.0 where lost logcontext warnings would be emitted from timeouts in sync and requests made by Synapse itself. ([\#19090](https://github.com/element-hq/synapse/issues/19090))
+- Fix a bug introdued in 1.140.0 where lost logcontext warning were emitted when using `HomeServer.shutdown()`. ([\#19108](https://github.com/element-hq/synapse/issues/19108))

+# Admin Space Hierarchy Endpoint
+
+This API allows an admin to fetch the space/room hierarchy for a given space, 
+returning details about that room and any children the room may have, paginating
+over the space tree in a depth-first manner to locate child rooms. This is
+functionally similar to the [CS Hierarchy](https://spec.matrix.org/v1.16/client-server-api/#get_matrixclientv1roomsroomidhierarchy) endpoint but does not check for
+room membership when returning room summaries.
+
+The endpoint does not query other servers over federation about remote rooms
+that the server has not joined. This is a deliberate trade-off: while this
+means it will leave some holes in the hierarchy that we could otherwise
+sometimes fill in, it significantly improves the endpoint's response time and
+the admin endpoint is designed for managing rooms local to the homeserver
+anyway.
+
+**Parameters**
+
+The following query parameters are available:
+
+* `from` - An optional pagination token, provided when there are more rooms to 
+    return than the limit. 
+* `limit` - Maximum amount of rooms to return. Must be a non-negative integer,
+   defaults to `50`.
+* `max_depth` - The maximum depth in the tree to explore, must be a non-negative
+   integer. 0 would correspond to just the root room, 1 would include just the
+   root room's children, etc.  If not provided will recurse into the space tree without limit.

+# Release notes review checklist
+
+The Synapse release process includes a step to review the changelog before
+publishing it. The following is a list of common points to check for:
+
+1. Check whether any similar entries that can be merged together (make sure to include all mentioned PRs at the end of the line, i.e. (#1234, #1235, ...)).
+2. Link any MSCXXXX lines to the Matrix Spec Change itself: <https://github.com/matrix-org/matrix-spec-proposals/pull/xxxx>.
+3. Wrap any class names, variable names, etc. in back-ticks, if needed.
+4. Hoist any relevant security, deprecation, etc. announcements to the top of this version's changelog for visibility. This includes any announcements in RCs for this release.
+5. Check the upgrade notes for any important announcements, and link to them from the changelog if warranted.
+6. Quickly skim and check that each entry is in the appropriate section.
+7. Entries under the Bugfixes section should ideally state what Synapse version the bug was introduced in. For example: "Fixed a bug introduced in v1.x.y" or if no version can be identified, "Fixed a long-standing bug ...".

+## Cheatsheet for creating a new stream
+
+These rough notes and links may help you to create a new stream and add all the
+necessary registration and event handling.
+
+**Create your stream:**
+- [create a stream class and stream row class](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/replication/tcp/streams/_base.py#L728)
+  - will need an [ID generator](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/storage/databases/main/thread_subscriptions.py#L75)
+    - may need [writer configuration](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/config/workers.py#L177), if there isn't already an obvious source of configuration for which workers should be designated as writers to your new stream.
+      - if adding new writer configuration, add Docker-worker configuration, which lets us configure the writer worker in Complement tests: [[1]](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/docker/configure_workers_and_start.py#L331), [[2]](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/docker/configure_workers_and_start.py#L440)
+- most of the time, you will likely introduce a new datastore class for the concept represented by the new stream, unless there is already an obvious datastore that covers it.
+- consider whether it may make sense to introduce a handler
+
+**Register your stream in:**
+- [`STREAMS_MAP`](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/replication/tcp/streams/__init__.py#L71)
+
+**Advance your stream in:**
+- [`process_replication_position` of your appropriate datastore](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/storage/databases/main/thread_subscriptions.py#L111)
+  - don't forget the super call
+
+**If you're going to do any caching that needs invalidation from new rows:**
+- add invalidations to [`process_replication_rows` of your appropriate datastore](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/storage/databases/main/thread_subscriptions.py#L91)

+
+**For streams to be used in sync:**
+- add a new field to [`StreamToken`](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/types/__init__.py#L1003)

+  - locally on the same worker when completing a write, [e.g. in your handler](https://github.com/element-hq/synapse/blob/4367fb2d078c52959aeca0fe6874539c53e8360d/synapse/handlers/thread_subscriptions.py#L139)
