Toggle v1.57.1's commit message
Synapse 1.57.1 (2022-04-20)

===========================

This is a patch release that only affects the Docker image. It is only of interest to administrators using [the LDAP module][LDAPModule] to authenticate their users.
If you have already upgraded to Synapse 1.57.0 without problem, then you have no need to upgrade to this patch release.

[LDAPModule]: https://github.com/matrix-org/matrix-synapse-ldap3

Updates to the Docker image
---------------------------

- Include version 0.2.0 of the Synapse LDAP Auth Provider module in the Docker image. This matches the version that was present in the Docker image for Synapse v1.56.0. ([\matrix-org#12512](matrix-org#12512))

v1.57.0

Toggle v1.57.0's commit message
Synapse 1.57.0 (2022-04-19)

===========================

This version includes a [change](matrix-org#12209) to the way transaction IDs are managed for application services. If your deployment uses a dedicated worker for application service traffic, **it must be stopped** when the database is upgraded (which normally happens when the main process is upgraded), to ensure the change is made safely without any risk of reusing transaction IDs.

See the [upgrade notes](https://github.com/matrix-org/synapse/blob/v1.57.0rc1/docs/upgrade.md#upgrading-to-v1570) for more details.

No significant changes since 1.57.0rc1.

Synapse 1.57.0rc1 (2022-04-12)
==============================

Features
--------

- Send device list changes to application services as specified by [MSC3202](matrix-org/matrix-spec-proposals#3202), using unstable prefixes. The `msc3202_transaction_extensions` experimental homeserver config option must be enabled and `org.matrix.msc3202: true` must be present in the application service registration file for device list changes to be sent. The "left" field is currently always empty. ([\matrix-org#11881](matrix-org#11881))
- Optimise fetching large quantities of missing room state over federation. ([\matrix-org#12040](matrix-org#12040))
- Offload the `update_client_ip` background job from the main process to the background worker, when using Redis-based replication. ([\matrix-org#12251](matrix-org#12251))
- Move `update_client_ip` background job from the main process to the background worker. ([\matrix-org#12252](matrix-org#12252))
- Add a module callback to react to new 3PID (email address, phone number) associations. ([\matrix-org#12302](matrix-org#12302))
- Add a configuration option to remove a specific set of rooms from sync responses. ([\matrix-org#12310](matrix-org#12310))
- Add a module callback to react to account data changes. ([\matrix-org#12327](matrix-org#12327))
- Allow setting user admin status using the module API. Contributed by Famedly. ([\matrix-org#12341](matrix-org#12341))
- Reduce overhead of restarting synchrotrons. ([\matrix-org#12367](matrix-org#12367), [\matrix-org#12372](matrix-org#12372))
- Update `/messages` to use historic pagination tokens if no `from` query parameter is given. ([\matrix-org#12370](matrix-org#12370))
- Add a module API for reading and writing global account data. ([\matrix-org#12391](matrix-org#12391))
- Support the stable `v1` endpoint for `/relations`, per [MSC2675](matrix-org/matrix-spec-proposals#2675). ([\matrix-org#12403](matrix-org#12403))
- Include bundled aggregations in search results
  ([MSC3666](matrix-org/matrix-spec-proposals#3666)). ([\matrix-org#12436](matrix-org#12436))

Bugfixes
--------

- Fix a long-standing bug where events from ignored users were still considered for bundled aggregations. ([\matrix-org#12235](matrix-org#12235), [\matrix-org#12338](matrix-org#12338))
- Fix non-member state events not resolving for historical events when used in [MSC2716](matrix-org/matrix-spec-proposals#2716) `/batch_send` `state_events_at_start`. ([\matrix-org#12329](matrix-org#12329))
- Fix a long-standing bug affecting URL previews that would generate a 500 response instead of a 403 if the previewed URL includes a port that isn't allowed by the relevant blacklist. ([\matrix-org#12333](matrix-org#12333))
- Default to `private` room visibility rather than `public` when a client does not specify one, according to spec. ([\matrix-org#12350](matrix-org#12350))
- Fix a spec compliance issue where requests to the `/publicRooms` federation API would specify `limit` as a string. ([\matrix-org#12364](matrix-org#12364), [\matrix-org#12410](matrix-org#12410))
- Fix a bug introduced in Synapse 1.49.0 which caused the `synapse_event_persisted_position` metric to have invalid values. ([\matrix-org#12390](matrix-org#12390))

Synapse 1.56.0 (2022-04-05)

===========================

Synapse will now refuse to start up if open registration is enabled, in order to help mitigate
abuse across the federation. If you would like
to provide registration to anyone, consider adding [email](https://github.com/matrix-org/synapse/blob/8a519f8abc6de772167c2cca101d22ee2052fafc/docs/sample_config.yaml#L1285),
[recaptcha](https://matrix-org.github.io/synapse/v1.56/CAPTCHA_SETUP.html)
or [token-based](https://matrix-org.github.io/synapse/v1.56/usage/administration/admin_api/registration_tokens.html) verification
in order to prevent automated registration from bad actors.
This check can be disabled by setting the `enable_registration_without_verification` option in your
homeserver configuration file to `true`. More details are available in the
[upgrade notes](https://matrix-org.github.io/synapse/v1.56/upgrade.html#open-registration-without-verification-is-now-disabled-by-default).

Synapse will additionally now refuse to start when using PostgreSQL with a non-`C` values for `COLLATE` and `CTYPE`, unless
the config flag `allow_unsafe_locale`, found in the database section of the configuration file, is set to `true`. See the
[upgrade notes](https://matrix-org.github.io/synapse/v1.56/upgrade#change-in-behaviour-for-postgresql-databases-with-unsafe-locale)
for details.

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

- Bump the version of `black` for compatibility with the latest `click` release. ([\matrix-org#12320](matrix-org#12320))

Synapse 1.55.2 (2022-03-24)

===========================

This patch version reverts the earlier fixes from Synapse 1.55.1, which could cause problems in certain deployments, and instead adds a cap to the version of Jinja to be installed. Again, this is to fix an incompatibility with version 3.1.0 of the [Jinja](https://pypi.org/project/Jinja2/) library, and again, deployments of Synapse using the `matrixdotorg/synapse` Docker image or Debian packages from packages.matrix.org are not affected.

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

- Pin Jinja to <3.1.0, as Synapse fails to start with Jinja 3.1.0. ([\matrix-org#12297](matrix-org#12297))
- Revert changes from 1.55.1 as they caused problems with older versions of Jinja ([\matrix-org#12296](matrix-org#12296))

v1.55.1

Synapse 1.55.1 (2022-03-24)

===========================

This is a patch release that fixes an incompatibility with version 3.1.0 of the [Jinja](https://pypi.org/project/Jinja2/) library, released on March 24th, 2022. Deployments of Synapse using the `matrixdotorg/synapse` Docker image or Debian packages from packages.matrix.org are not affected.

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

- Remove uses of the long-deprecated `jinja2.Markup` which would prevent Synapse from starting with Jinja 3.1.0 or above installed. ([\matrix-org#12289](matrix-org#12289))

v1.55.0

Toggle v1.55.0's commit message
Synapse 1.55.0 (2022-03-22)

===========================

This release removes a workaround introduced in Synapse 1.50.0 for Mjolnir compatibility. **This breaks compatibility with Mjolnir 1.3.1 and earlier. ([\matrix-org#11700](matrix-org#11700; Mjolnir users should upgrade Mjolnir before upgrading Synapse to this version.

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

- Tweak copy for default Single Sign-On account details template to better adhere to mobile app store guidelines. ([\matrix-org#12265](matrix-org#12265), [\matrix-org#12260](matrix-org#12260))
