validate_event_for_room_version and check_auth_rules_for_event both take a dedicated room_version parameter, which is redundant because it is the same as event.room_version.

Apart from simplifying the interface, this also means we can get rid of a few store.get_room_version calls.

The parameter was added in #4482 (though the code has evolved a lot since then), but it's been redundant since #6875 gave events their own room version property.

Should be reviewable commit-by-commit.

I'm guessing something else earlier will reject the event when we attempt to create it? (So this code essentially is dead code.)

sorry, I meant to say that. Yes, indeed.

LGTM! Not sure what's up with complement failures though.

EventAuthTestCase: build events for the right room version
2959184 
In practice, when we run the auth rules, all of the events have the right room
version. Let's stop building Room V1 events for these tests and use the right
version.

Remove room_version param from validate_event_for_room_version
68be42f 
Instead, use the `room_version` property of the event we're validating.

The `room_version` was originally added as a parameter somewhere around #4482,
but really it's been redundant since #6875 added a `room_version` field to `EventBase`.

It's now implied by the room_version property on the event.

Synapse 1.62.0 (2022-07-05)
===========================

No significant changes since 1.62.0rc3.

Authors of spam-checker plugins should consult the [upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.62/docs/upgrade.md#upgrading-to-v1620) to learn about the enriched signatures for spam checker callbacks, which are supported with this release of Synapse.

Synapse 1.62.0rc3 (2022-07-04)
==============================

Bugfixes
--------

- Update the version of the [ldap3 plugin](https://github.com/matrix-org/matrix-synapse-ldap3/) included in the `matrixdotorg/synapse` DockerHub images and the Debian packages hosted on `packages.matrix.org` to 0.2.1. This fixes [a bug](matrix-org/matrix-synapse-ldap3#163) with usernames containing uppercase characters. ([\matrix-org#13156](matrix-org#13156))
- Fix a bug introduced in Synapse 1.62.0rc1 affecting unread counts for users on small servers. ([\matrix-org#13168](matrix-org#13168))

Synapse 1.62.0rc2 (2022-07-01)
==============================

Bugfixes
--------

- Fix unread counts for users on large servers. Introduced in v1.62.0rc1. ([\matrix-org#13140](matrix-org#13140))
- Fix DB performance when deleting old push notifications. Introduced in v1.62.0rc1. ([\matrix-org#13141](matrix-org#13141))

Synapse 1.62.0rc1 (2022-06-28)
==============================

Features
--------

- Port the spam-checker API callbacks to a new, richer API. This is part of an ongoing change to let spam-checker modules inform users of the reason their event or operation is rejected. ([\matrix-org#12857](matrix-org#12857), [\matrix-org#13047](matrix-org#13047))
- Allow server admins to customise the response of the `/.well-known/matrix/client` endpoint. ([\matrix-org#13035](matrix-org#13035))
- Add metrics measuring the CPU and DB time spent in state resolution. ([\matrix-org#13036](matrix-org#13036))
- Speed up fetching of device list changes in `/sync` and `/keys/changes`. ([\matrix-org#13045](matrix-org#13045), [\matrix-org#13098](matrix-org#13098))
- Improve URL previews for sites which only provide Twitter Card metadata, e.g. LWN.net. ([\matrix-org#13056](matrix-org#13056))

Bugfixes
--------

- Update [MSC3786](matrix-org/matrix-spec-proposals#3786) implementation to check `state_key`. ([\matrix-org#12939](matrix-org#12939))
- Fix a bug introduced in Synapse 1.58 where Synapse would not report full version information when installed from a git checkout. This is a best-effort affair and not guaranteed to be stable. ([\matrix-org#12973](matrix-org#12973))
- Fix a bug introduced in Synapse 1.60 where Synapse would fail to start if the `sqlite3` module was not available. ([\matrix-org#12979](matrix-org#12979))
- Fix a bug where non-standard information was required when requesting the `/hierarchy` API over federation. Introduced
  in Synapse v1.41.0. ([\matrix-org#12991](matrix-org#12991))
- Fix a long-standing bug which meant that rate limiting was not restrictive enough in some cases. ([\matrix-org#13018](matrix-org#13018))
- Fix a bug introduced in Synapse 1.58 where profile requests for a malformed user ID would ccause an internal error. Synapse now returns 400 Bad Request in this situation. ([\matrix-org#13041](matrix-org#13041))
- Fix some inconsistencies in the event authentication code. ([\matrix-org#13087](matrix-org#13087), [\matrix-org#13088](matrix-org#13088))
- Fix a long-standing bug where room directory requests would cause an internal server error if given a malformed room alias. ([\matrix-org#13106](matrix-org#13106))

Improved Documentation
----------------------

- Add documentation for how to configure Synapse with Workers using Docker Compose. Includes example worker config and docker-compose.yaml. Contributed by @Thumbscrew. ([\matrix-org#12737](matrix-org#12737))
- Ensure the [Poetry cheat sheet](https://matrix-org.github.io/synapse/develop/development/dependencies.html) is available in the online documentation. ([\matrix-org#13022](matrix-org#13022))
- Mention removed community/group worker endpoints in upgrade.md. Contributed by @olmari. ([\matrix-org#13023](matrix-org#13023))
- Add instructions for running Complement with `gotestfmt`-formatted output locally. ([\matrix-org#13073](matrix-org#13073))
- Update OpenTracing docs to reference the configuration manual rather than the configuration file. ([\matrix-org#13076](matrix-org#13076))
- Update information on downstream Debian packages. ([\matrix-org#13095](matrix-org#13095))
- Remove documentation for the Delete Group Admin API which no longer exists. ([\matrix-org#13112](matrix-org#13112))

Deprecations and Removals
-------------------------

- Remove the unspecced `DELETE /directory/list/room/{roomId}` endpoint, which hid rooms from the [public room directory](https://spec.matrix.org/v1.3/client-server-api/#listing-rooms). Instead, `PUT` to the same URL with a visibility of `"private"`. ([\matrix-org#13123](matrix-org#13123))

Internal Changes
----------------

- Add tests for cancellation of `GET /rooms/$room_id/members` and `GET /rooms/$room_id/state` requests. ([\matrix-org#12674](matrix-org#12674))
- Report login failures due to unknown third party identifiers in the same way as failures due to invalid passwords. This prevents an attacker from using the error response to determine if the identifier exists. Contributed by Daniel Aloni. ([\matrix-org#12738](matrix-org#12738))
- Merge the Complement testing Docker images into a single, multi-purpose image. ([\matrix-org#12881](matrix-org#12881), [\matrix-org#13075](matrix-org#13075))
- Simplify the database schema for `event_edges`. ([\matrix-org#12893](matrix-org#12893))

- Add `Cross-Origin-Resource-Policy: cross-origin` header to content repository's thumbnail and download endpoints. ([\matrix-org#12944](matrix-org#12944))
- Replace noop background updates with `DELETE` delta. ([\matrix-org#12954](matrix-org#12954), [\matrix-org#13050](matrix-org#13050))
- Use lower isolation level when inserting read receipts to avoid serialization errors. Contributed by Nick @ Beeper. ([\matrix-org#12957](matrix-org#12957))
- Reduce the amount of state we pull from the DB. ([\matrix-org#12963](matrix-org#12963))
- Enable testing against PostgreSQL databases in Complement CI. ([\matrix-org#12965](matrix-org#12965), [\matrix-org#13034](matrix-org#13034))
- Fix an inaccurate comment. ([\matrix-org#12969](matrix-org#12969))
- Remove the `delete_device` method and always call `delete_devices`. ([\matrix-org#12970](matrix-org#12970))
- Use a GitHub form for issues rather than a hard-to-read, easy-to-ignore template. ([\matrix-org#12982](matrix-org#12982))

- Faster joins: add issue links to the TODO comments in the code. ([\matrix-org#13004](matrix-org#13004))
- Reduce DB usage of `/sync` when a large number of unread messages have recently been sent in a room. ([\matrix-org#13005](matrix-org#13005), [\matrix-org#13096](matrix-org#13096), [\matrix-org#13118](matrix-org#13118))
- Replaced usage of PyJWT with methods from Authlib in `org.matrix.login.jwt`. Contributed by Hannes Lerchl. ([\matrix-org#13011](matrix-org#13011))
