In line with our [deprecation policy](https://github.com/element-hq/synapse/blob/develop/docs/deprecation_policy.md), we've dropped
support for PostgreSQL 13, as it is no longer supported upstream.
This release of Synapse requires PostgreSQL 14+.

- Fixes docker image creation in the release workflow.

- Support multiple config files in `register_new_matrix_user`. ([\#18784](https://github.com/element-hq/synapse/issues/18784))
- Remove authentication from `POST /_matrix/client/v1/delayed_events`, and allow calling this endpoint with the update action to take (`send`/`cancel`/`restart`) in the request path instead of the body. ([\#19152](https://github.com/element-hq/synapse/issues/19152))

- Fixed a longstanding bug where background updates were only run on the `main` database. ([\#19181](https://github.com/element-hq/synapse/issues/19181))
- Fixed a bug introduced in v1.142.0 preventing subpaths in MAS endpoints from working. ([\#19186](https://github.com/element-hq/synapse/issues/19186))
- Fix the SQLite-to-PostgreSQL migration script to correctly migrate a boolean column in the `delayed_events` table. ([\#19155](https://github.com/element-hq/synapse/issues/19155))

- Improve documentation around streams, particularly ID generators and adding new streams. ([\#18943](https://github.com/element-hq/synapse/issues/18943))

- Remove support for PostgreSQL 13. ([\#19170](https://github.com/element-hq/synapse/issues/19170))

- Provide additional servers with federation room directory results. ([\#18970](https://github.com/element-hq/synapse/issues/18970))
- Add a shortcut return when there are no events to purge. ([\#19093](https://github.com/element-hq/synapse/issues/19093))
- Write union types as `X | Y` where possible, as per PEP 604, added in Python 3.10. ([\#19111](https://github.com/element-hq/synapse/issues/19111))
- Reduce cardinality of `synapse_storage_events_persisted_events_sep_total` metric by removing `origin_entity` label. This also separates out events sent by local application services by changing the `origin_type` for such events to `application_service`. The `type` field also only tracks common event types, and anything else is bucketed under `*other*`.

    - Fixes docker image creation in the release workflow.

  • v1.143.0rc1

    f5bf02ef · 1.143.0rc1 · 
    In line with our [deprecation policy](https://github.com/element-hq/synapse/blob/develop/docs/deprecation_policy.md), we've dropped
support for PostgreSQL 13, as it is no longer supported upstream.
This release of Synapse requires PostgreSQL 14+.

- Support multiple config files in `register_new_matrix_user`. ([\#18784](https://github.com/element-hq/synapse/issues/18784))
- Remove authentication from `POST /_matrix/client/v1/delayed_events`, and allow calling this endpoint with the update action to take (`send`/`cancel`/`restart`) in the request path instead of the body. ([\#19152](https://github.com/element-hq/synapse/issues/19152))

- Fixed a longstanding bug where background updates were only run on the `main` database. ([\#19181](https://github.com/element-hq/synapse/issues/19181))
- Fixed a bug introduced in v1.142.0 preventing subpaths in MAS endpoints from working. ([\#19186](https://github.com/element-hq/synapse/issues/19186))
- Fix the SQLite-to-PostgreSQL migration script to correctly migrate a boolean column in the `delayed_events` table. ([\#19155](https://github.com/element-hq/synapse/issues/19155))

- Improve documentation around streams, particularly ID generators and adding new streams. ([\#18943](https://github.com/element-hq/synapse/issues/18943))

- Remove support for PostgreSQL 13. ([\#19170](https://github.com/element-hq/synapse/issues/19170))

- Provide additional servers with federation room directory results. ([\#18970](https://github.com/element-hq/synapse/issues/18970))

- Write union types as `X | Y` where possible, as per PEP 604, added in Python 3.10. ([\#19111](https://github.com/element-hq/synapse/issues/19111))
- Reduce cardinality of `synapse_storage_events_persisted_events_sep_total` metric by removing `origin_entity` label. This also separates out events sent by local application services by changing the `origin_type` for such events to `application_service`. The `type` field also only tracks common event types, and anything else is bucketed under `*other*`. ([\#19133](https://github.com/element-hq/synapse/issues/19133), [\#19168](https://github.com/element-hq/synapse/issues/19168))

  • v1.142.1

    46efbae4 · 1.142.1 · 
    - Fixed a bug introduced in v1.142.0 preventing subpaths in MAS endpoints from working. ([\#19186](https://github.com/element-hq/synapse/issues/19186))

  • v1.142.0

    8feb862f · 1.142.0 · 
    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).

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.

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!

- Properly stop building wheels for Python 3.9 and free-threaded CPython. ([\#19154](https://github.com/element-hq/synapse/issues/19154))

- 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))

- 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))

- Manually skip building Python 3.9 wheels, to prevent errors in the release workflow. ([\#19119](https://github.com/element-hq/synapse/issues/19119))

- Add support for Python 3.14. ([\#19055](https://github.com/element-hq/synapse/issues/19055), [\#19134](https://github.com/element-hq/synapse/issues/19134))
- Add an [Admin API](https://element-hq.github.io/synapse/latest/usage/administration/admin_api/index.html)
  to allow an admin to fetch the space/room hierarchy for a given space. ([\#19021](https://github.com/element-hq/synapse/issues/19021))

- Fix a bug introduced in 1.111.0 where failed attempts to download authenticated remote media would not be handled correctly. ([\#19062](https://github.com/element-hq/synapse/issues/19062))
- 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))

- Update the link to the Debian oldstable package for SQLite. ([\#19047](https://github.com/element-hq/synapse/issues/19047))
- Point out additional Redis configuration options available in the worker docs. Contributed by @servisbryce. ([\#19073](https://github.com/element-hq/synapse/issues/19073))
- Update the list of Debian releases that the downstream Debian package is maintained for. ([\#19100](https://github.com/element-hq/synapse/issues/19100))
- Add [a page](https://element-hq.github.io/synapse/latest/development/internal_documentation/release_notes_review_checklist.html) to the documentation describing the steps the Synapse team takes to review the release notes before publishing them.

- Remove logcontext problems caused by awaiting raw `deferLater(...)`. ([\#19058](https://github.com/element-hq/synapse/issues/19058))
- Prevent duplicate logging setup when running multiple Synapse instances. ([\#19067](https://github.com/element-hq/synapse/issues/19067))
- Be mindful of other logging context filters in 3rd-party code and avoid overwriting log record fields unless we know the log record is relevant to Synapse. ([\#19068](https://github.com/element-hq/synapse/issues/19068))
- Update pydantic to v2. ([\#19071](https://github.com/element-hq/synapse/issues/19071))
