  • v1.71.0
    Synapse 1.71.0 (2022-11-08)
    ===========================
    
    Please note that, as announced in the release notes for Synapse 1.69.0, legacy Prometheus metric names are now disabled by default.
    They will be removed altogether in Synapse 1.73.0.
    If not already done, server administrators should update their dashboards and alerting rules to avoid using the deprecated metric names.
    See the [upgrade notes](https://matrix-org.github.io/synapse/v1.71/upgrade.html#upgrading-to-v1710) for more details.
    
    **Note:** in line with our [deprecation policy](https://matrix-org.github.io/synapse/latest/deprecation_policy.html) for platform dependencies, this will be the last release to support PostgreSQL 10, which reaches upstream end-of-life on November 10th, 2022. Future releases of Synapse will require PostgreSQL 11+.
    
    No significant changes since 1.71.0rc2.

    Synapse 1.67.0 (2022-09-13)
    ===========================
    
    This release removes using the deprecated direct TCP replication configuration
    for workers. Server admins should use Redis instead. See the [upgrade
    notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670).
    
    The minimum version of `poetry` supported for managing source checkouts is now
    1.2.0.
    
    **Notice:** from the next major release (1.68.0) installing Synapse from a source
    checkout will require a recent Rust compiler. Those using packages or
    `pip install matrix-synapse` will not be affected. See the [upgrade
    notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670).
    
    **Notice:** from the next major release (1.68.0), running Synapse with a SQLite
    database will require SQLite version 3.27.0 or higher. (The [current minimum
     version is SQLite 3.22.0](https://github.com/matrix-org/synapse/blob/release-v1.67/synapse/storage/engines/sqlite.py#L69-L78).)
    See [#12983](https://github.com/matrix-org/synapse/issues/12983) and the [upgrade notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670) for more details.
    
    No significant changes since 1.67.0rc1.

    --------
    
    - Fix a bug introduced in Synapse 1.13 where the [List Rooms admin API](https://matrix-org.github.io/synapse/develop/admin_api/rooms.html#list-room-api) would return integers instead of booleans for the `federatable` and `public` fields when using a Sqlite database. ([\#13509](https://github.com/matrix-org/synapse/issues/13509))
    - Fix bug that user cannot `/forget` rooms after the last member has left the room. ([\#13546](https://github.com/matrix-org/synapse/issues/13546))

    - Fix [MSC3030](https://github.com/matrix-org/matrix-spec-proposals/pull/3030) `/timestamp_to_event` endpoint to return the correct next event when the events have the same timestamp. ([\#13658](https://github.com/matrix-org/synapse/issues/13658))
    - Fix bug where we wedge media plugins if clients disconnect early. Introduced in v1.22.0. ([\#13660](https://github.com/matrix-org/synapse/issues/13660))
    - Fix a long-standing bug which meant that keys for unwhitelisted servers were not returned by `/_matrix/key/v2/query`. ([\#13683](https://github.com/matrix-org/synapse/issues/13683))
    - Fix a bug introduced in Synapse v1.20.0 that would cause the unstable unread counts from [MSC2654](https://github.com/matrix-org/matrix-spec-proposals/pull/2654) to be calculated even if the feature is disabled. ([\#13694](https://github.com/matrix-org/synapse/issues/13694))
    
    Updates to the Docker image
    ---------------------------
    
    - Update docker image to use a stable version of poetry. ([\#13688](https://github.com/matrix-org/synapse/issues/13688))
    
    Improved Documentation
    ----------------------
    
    - Improve the description of the ["chain cover index"](https://matrix-org.github.io/synapse/latest/auth_chain_difference_algorithm.html) used internally by Synapse. ([\#13602](https://github.com/matrix-org/synapse/issues/13602))
    - Document how ["monthly active users"](https://matrix-org.github.io/synapse/latest/usage/administration/monthly_active_users.html) is calculated and used. ([\#13617](https://github.com/matrix-org/synapse/issues/13617))

    - Remove unintentional colons from [config manual](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html) headers. ([\#13665](https://github.com/matrix-org/synapse/issues/13665))
    - Update docs to make enabling metrics more clear. ([\#13678](https://github.com/matrix-org/synapse/issues/13678))
    - Clarify `(room_id, event_id)` global uniqueness and how we should scope our database schemas. ([\#13701](https://github.com/matrix-org/synapse/issues/13701))
    
    Deprecations and Removals
    -------------------------
    
    - Drop support for calling `/_matrix/client/v3/rooms/{roomId}/invite` without an `id_access_token`, which was not permitted by the spec. Contributed by @Vetchu. ([\#13241](https://github.com/matrix-org/synapse/issues/13241))

  • v1.67.0rc1
    ec2fe7bb · Fixup changelog ·
    Synapse 1.67.0rc1 (2022-09-06)
    ==============================
    
    This release removes using the deprecated direct TCP replication configuration
    for workers. Server admins should use Redis instead. See the [upgrade
    notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670).
    
    The minimum version of `poetry` supported for managing source checkouts is now
    1.2.0.
    
    Notice: from the next major release (v1.68.0) installing Synapse from a source
    checkout will require a recent Rust compiler. Those using packages or
    `pip install matrix-synapse` will not be affected. See the [upgrade
    notes](https://matrix-org.github.io/synapse/v1.67/upgrade.html#upgrading-to-v1670).
    
    Features
    --------
    
    - Support setting the registration shared secret in a file, via a new `registration_shared_secret_path` configuration option. ([\#13614](https://github.com/matrix-org/synapse/issues/13614))
    - Change the default startup behaviour so that any missing "additional" configuration files (signing key, etc) are generated automatically. ([\#13615](https://github.com/matrix-org/synapse/issues/13615))
    - Improve performance of sending messages in rooms with thousands of local users. ([\#13634](https://github.com/matrix-org/synapse/issues/13634))

  • v1.66.0
    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.

([\#13525](https://github.com/matrix-org/synapse/issues/13525))
    - 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`. ([\#13566](https://github.com/matrix-org/synapse/issues/13566))
    - Fix a bug where the `opentracing.force_tracing_for_users` config option would not apply to [`/sendToDevice`](https://spec.matrix.org/v1.3/client-server-api/#put_matrixclientv3sendtodeviceeventtypetxnid) and [`/keys/upload`](https://spec.matrix.org/v1.3/client-server-api/#post_matrixclientv3keysupload) requests.
