Add changelog

I noticed this in some profiling. Basically, we prune the ratelimiters
by copying and iterating over every entry every 60 seconds. Instead,
let's use a wheel timer to track when we should potentially prune a
given key, and then we a) check fewer keys, and b) can run more
frequently. Hopefully this should mean we don't have a large pause
everytime we prune a ratelimiter with lots of keys.

Also fixes a bug where we didn't prune entries that were added via
`record_action` and never subsequently updated. This affected the media
and joins-per-room ratelimiter.

+# Synapse 1.141.0 (2025-10-29)
+
+## 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).
+
+Publishing MacOS Python wheels will continue for the next few releases. 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!
+
+
+## Docker images now based on Debian `trixie` with Python 3.13
+
+The Docker images are now based on Debian `trixie` and use Python 3.13. If you
+are using the Docker images as a base image you may need to e.g. adjust the
+paths you mount any additional Python packages at.
+
+No significant changes since 1.141.0rc2.

+# Synapse 1.140.0 (2025-10-14)
+
+## Compatibility notice for users of `synapse-s3-storage-provider`
+
+Deployments that make use of the
+[synapse-s3-storage-provider](https://github.com/matrix-org/synapse-s3-storage-provider)
+module must upgrade to
+[v1.6.0](https://github.com/matrix-org/synapse-s3-storage-provider/releases/tag/v1.6.0).
+Using older versions of the module with this release of Synapse will prevent
+users from being able to upload or download media.
+
+
+No significant changes since 1.140.0rc1.
+
+
+
+
+# Synapse 1.140.0rc1 (2025-10-10)
+
+## Features
+
+- Add [a new Media Query by ID Admin API](https://element-hq.github.io/synapse/v1.140/admin_api/media_admin_api.html#query-a-piece-of-media-by-id) that allows server admins to query and investigate the metadata of local or cached remote media via
+  the `origin/media_id` identifier found in a [Matrix Content URI](https://spec.matrix.org/v1.14/client-server-api/#matrix-content-mxc-uris). ([\#18911](https://github.com/element-hq/synapse/issues/18911))

+- Add experimental implementation of the `GET /_matrix/client/v1/rtc/transports` endpoint for the latest draft of [MSC4143: MatrixRTC](https://github.com/matrix-org/matrix-spec-proposals/pull/4143). ([\#18967](https://github.com/element-hq/synapse/issues/18967))
+- Expose a `defer_to_threadpool` function in the Synapse Module API that allows modules to run a function on a separate thread in a custom threadpool. ([\#19032](https://github.com/element-hq/synapse/issues/19032))
+
+## Bugfixes

+
+## Deprecations and Removals
+
+- Remove deprecated `LoggingContext.set_current_context`/`LoggingContext.current_context` methods which already have equivalent bare methods in `synapse.logging.context`. ([\#18989](https://github.com/element-hq/synapse/issues/18989))
+- Drop support for unstable field names from the long-accepted [MSC2732](https://github.com/matrix-org/matrix-spec-proposals/pull/2732) (Olm fallback keys) proposal. ([\#18996](https://github.com/element-hq/synapse/issues/18996))
+

+- Reduce overall number of calls to `_get_e2e_cross_signing_signatures_for_devices` by increasing the batch size of devices the query is called with, reducing DB load. ([\#18939](https://github.com/element-hq/synapse/issues/18939))
+- Update error code used when an appservice tries to masquerade as an unknown device using [MSC4326](https://github.com/matrix-org/matrix-spec-proposals/pull/4326). Contributed by @tulir @ Beeper. ([\#18947](https://github.com/element-hq/synapse/issues/18947))
+- Fix `no active span when trying to log` tracing error on startup (when OpenTracing is enabled). ([\#18959](https://github.com/element-hq/synapse/issues/18959))

+- Remove internal `ReplicationUploadKeysForUserRestServlet` as a follow-up to the work in https://github.com/element-hq/synapse/pull/18581 that moved device changes off the main process. ([\#18988](https://github.com/element-hq/synapse/issues/18988))
+- Switch task scheduler from raw logcontext manipulation to using the dedicated logcontext utils. ([\#18990](https://github.com/element-hq/synapse/issues/18990))
+- Remove `MockClock()` in tests. ([\#18992](https://github.com/element-hq/synapse/issues/18992))
+- Switch back to our own custom `LogContextScopeManager` instead of OpenTracing's `ContextVarsScopeManager` which was causing problems when using the experimental `SYNAPSE_ASYNC_IO_REACTOR` option with tracing enabled. ([\#19007](https://github.com/element-hq/synapse/issues/19007))

+# 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 ...".
