Like #14974 but for element-hq/element-web#11070 - without this the Server header is not accessible to Web browser clients

Pull Request Checklist

  • Pull request is based on the develop branch
  • Pull request includes a changelog file. The entry should:
    • Be a short description of your change which makes sense to users. "Fixed a bug that prevented receiving messages from other servers." instead of "Moved X method from EventStore to EventWorkerStore.".
    • Use markdown where necessary, mostly for code blocks.
    • End with either a period (.) or an exclamation mark (!).
    • Start with a capital letter.
    • Feel free to credit yourself, by adding a sentence "Contributed by @github_username." or "Contributed by [Your Name]." to the end of the entry.
  • Pull request includes a sign off
  • Code style is correct
    (run the linters)

Seems sane. https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Server advises:

Warning: Avoid overly-detailed Server values, as they can reveal information that may make it (slightly) easier for attackers to exploit known security holes.

AFAICS the server header is set here https://github.com/matrix-org/synapse/blob/develop/synapse/http/site.py#L274

to the Synapse version, which we already expose1.

Footnotes

  1. Tracing it through (look for listen_http call sites), the version is VERSION defined in check_dependencies.py (and not SYNAPSE_VERSION defined in synapse.util --- why are there two? ↩

@t3chguy any particular reason for keeping this in draft? Shout if you want to land this as-is. (I haven't tested this but I can't see anything else that we did differently for the Trace-ID header.

This release
 - raises the minimum supported version of Python to 3.8, as Python 3.7 is now [end-of-life](https://devguide.python.org/versions/), and
 - removes deprecated config options related to worker deployment.

See [the upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.88/docs/upgrade.md#upgrading-to-v1880) for more information.

- Revert "Stop writing to column `user_id` of tables `profiles` and `user_filters`", which was introduced in Synapse 1.88.0rc1. ([\matrix-org#15953](matrix-org#15953))

- Add `not_user_type` param to the [list accounts admin API](https://matrix-org.github.io/synapse/v1.88/admin_api/user_admin_api.html#list-accounts). ([\matrix-org#15844](matrix-org#15844))

- Pin `pydantic` to `^=1.7.4` to avoid backwards-incompatible API changes from the 2.0.0 release.
  Contributed by @PaarthShah. ([\matrix-org#15862](matrix-org#15862))
- Correctly resize thumbnails with pillow version >=10. ([\matrix-org#15876](matrix-org#15876))

- Fixed header levels on the [Admin API "Users"](https://matrix-org.github.io/synapse/v1.87/admin_api/user_admin_api.html) documentation page. Contributed by @sumnerevans at @beeper. ([\matrix-org#15852](matrix-org#15852))
- Remove deprecated `worker_replication_host`, `worker_replication_http_port` and `worker_replication_http_tls` configuration options. ([\matrix-org#15872](matrix-org#15872))

- **Remove deprecated `worker_replication_host`, `worker_replication_http_port` and `worker_replication_http_tls` configuration options.** See the [upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.88/docs/upgrade.md#removal-of-worker_replication_-settings) for more details. ([\matrix-org#15860](matrix-org#15860))

- Add foreign key constraint to `event_forward_extremities`. ([\matrix-org#15751](matrix-org#15751), [\matrix-org#15907](matrix-org#15907))
- Add read/write style cross-worker locks. ([\matrix-org#15782](matrix-org#15782))
- Stop writing to column `user_id` of tables `profiles` and `user_filters`. ([\matrix-org#15787](matrix-org#15787))

- Add a timeout that aborts any Postgres statement taking more than 1 hour. ([\matrix-org#15853](matrix-org#15853))
- Fix the `devenv up` configuration which was ignoring the config overrides. ([\matrix-org#15854](matrix-org#15854))
- Optimised cleanup of old entries in `device_lists_stream`. ([\matrix-org#15861](matrix-org#15861))
- Update the Matrix clients link in the _It works! Synapse is running_ landing page. ([\matrix-org#15874](matrix-org#15874))
