Synapse 1.66.0 (2022-08-31)
===========================

No significant changes since 1.66.0rc2.

This release removes the ability for homeservers to delegate email ownership
verification and password reset confirmation to identity servers. This removal
was originally planned for Synapse 1.64, but was later deferred until now. See
the [upgrade notes](https://matrix-org.github.io/synapse/v1.66/upgrade.html#upgrading-to-v1660) for more details.

Deployments with multiple workers should note that the direct TCP replication
configuration was deprecated in Synapse v1.18.0 and will be removed in Synapse
v1.67.0. In particular, the TCP `replication` [listener](https://matrix-org.github.io/synapse/v1.66/usage/configuration/config_documentation.html#listeners)
type (not to be confused with the `replication` resource on the `http` listener
type) and the `worker_replication_port` config option will be removed .

To migrate to Redis, add the [`redis` config](https://matrix-org.github.io/synapse/v1.66/workers.html#shared-configuration),
then remove the TCP `replication` listener from config of the master and
`worker_replication_port` from worker config. Note that a HTTP listener with a
`replication` resource is still required. See the
[worker documentation](https://matrix-org.github.io/synapse/v1.66/workers.html)
for more details.

Synapse 1.66.0rc2 (2022-08-30)
==============================

Bugfixes
--------

- Fix a bug introduced in Synapse 1.52.0 where sending server notices fails if `max_avatar_size` or `allowed_avatar_mimetypes` is set and not `system_mxid_avatar_url`. ([\matrix-org#13566](matrix-org#13566))

- Add missing links in `user_consent` section of configuration manual. ([\matrix-org#13536](matrix-org#13536))
- Fix the doc and some warnings that were referring to the nonexistent `custom_templates_directory` setting (instead of `custom_template_directory`). ([\matrix-org#13538](matrix-org#13538))

Deprecations and Removals

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.

## Security advisory

The following issue is fixed in 1.62.0.

* [GHSA-jhjh-776m-4765](https://github.com/matrix-org/synapse/security/advisories/GHSA-jhjh-776m-4765) / [CVE-2022-31152](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-31152)

Synapse instances prior to 1.62.0 did not implement the Matrix [event authorization rules](https://spec.matrix.org/v1.3/rooms/v10/#authorization-rules) correctly. An attacker could craft events which would be accepted by Synapse but not a spec-conformant server, potentially causing divergence in the room state between servers.

Homeservers with federation disabled via the [`federation_domain_whitelist`](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#federation_domain_whitelist) config option are unaffected.

Administrators of homeservers with federation enabled are advised to upgrade to v1.62.0 or higher.

Fixed by [#13087](https://github.com/matrix-org/synapse/pull/13087) and [#13088](https://github.com/matrix-org/synapse/pull/13088).
