* Tue Sep 21 2021 Marcus Rueckert <>
  - Update to 1.43.0
    This release drops support for the deprecated, unstable API for
    MSC2858, as well as the undocumented experimental.msc2858_enabled
    config option. Client authors should update their clients to use
    the stable API, available since Synapse 1.30.
    - Features
    - Allow room creators to send historical events specified by
      MSC2716 in existing room versions. (#10566)
    - Add config option to use non-default manhole password and
      keys. (#10643)
    - Skip final GC at shutdown to improve restart performance.
    - Allow configuration of the oEmbed URLs used for URL previews.
      (#10714, #10759)
    - Prefer room version 9 for restricted rooms per the room
      version capabilities API. (#10772)
    - Bugfixes
    - Added opentracing logging to help debug #9424. (#10828)
    - Fix a long-standing bug where room avatars were not included
      in email notifications. (#10658)
    - Fix a bug where the ordering algorithm was skipping the
      origin_server_ts step in the spaces summary resulting in
      unstable room orderings. (#10730)
    - Fix edge case when persisting events into a room where there
      are multiple events we previously hadn't calculated auth
      chains for (and hadn't marked as needing to be calculated).
    - Fix a bug which prevented calls to /createRoom that included
      the room_alias_name parameter from being handled by worker
      processes. (#10757)
    - Fix a bug which prevented user registration via SSO to
      require consent tracking for SSO mapping providers that don't
      prompt for Matrix ID selection. Contributed by @AndrewFerr.
    - Only return the stripped state events for the
      events in a room for the spaces summary from MSC2946.
    - Properly handle room upgrades of spaces. (#10774)
    - Fix a bug which generated invalid homeserver config when the
      frontend_proxy worker type was passed to the Synapse
      Worker-based Complement image. (#10783)
    - Improved Documentation
    - Minor fix to the media_repository developer documentation.
      Contributed by @cuttingedge1109. (#10556)

      has been deprecated since Synapse 1.35. Client authors should
      update their clients to use the stable API introduced in
      Synapse 1.30 if they have not already done so. (#10693)
    - Internal Changes
    - Add OpenTracing logging to help debug stuck messages (as
      described by issue #9424). (#10704)

  - Update to 1.41.1 (boo#1190037 boo#1190038)
    Due to the two security issues highlighted below, server
    administrators are encouraged to update Synapse. We are not aware
    of these vulnerabilities being exploited in the wild.
    - Security advisory
      The following issues are fixed in v1.41.1.
    - GHSA-3x4c-pq33-4w3q / CVE-2021-39164: Enumerating a private
      room's list of members and their display names.
      If an unauthorized user both knows the Room ID of a private
      room and that room's history visibility is set to shared,
      then they may be able to enumerate the room's members,
      including their display names.
      The unauthorized user must be on the same homeserver as a
      user who is a member of the target room.
      Fixed by 52c7a51cf.
    - GHSA-jj53-8fmw-f2w2 / CVE-2021-39163: Disclosing a private
      room's name, avatar, topic, and number of members.
      If an unauthorized user knows the Room ID of a private room,
      then its name, avatar, topic, and number of members may be
      disclosed through Group / Community features.
      The unauthorized user must be on the same homeserver as a
      user who is a member of the target room, and their homeserver
      must allow non-administrators to create groups
      (enable_group_creation in the Synapse configuration; off by
      Fixed by cb35df940a, #10723.

  - Update to 1.37.1
    This release resolves issues (such as #9490) where one busy room
    could cause head-of-line blocking, starving Synapse from
    processing events in other rooms, and causing all federated
    traffic to fall behind. Synapse 1.37.1 processes inbound
    federation traffic asynchronously, ensuring that one busy room
    won't impact others. Please upgrade to Synapse 1.37.1 as soon as
    possible, in order to increase resilience to other traffic
    - Features
    - Handle inbound events from federation asynchronously.
      (#10269, #10272)
* Tue Jun 29 2021 Marcus Rueckert <>
  - Update to 1.37.0
    This release deprecates the current spam checker interface. See
    the upgrade notes for more information on how to update to the
    new generic module interface.
    This release also removes support for fetching and renewing TLS
    certificates using the ACME v1 protocol, which has been fully
    decommissioned by Let's Encrypt on June 1st 2021. Admins
    previously using this feature should use a reverse proxy to
    handle TLS termination, or use an external ACME client (such as
    certbot) to retrieve a certificate and key and provide them to
    Synapse using the tls_certificate_path and tls_private_key_path
    configuration settings.

* Fri Mar 26 2021 Marcus Rueckert <>
  - Update to 1.30.1
    This release is identical to Synapse 1.30.0, with the exception
    of explicitly setting a minimum version of Python's Cryptography
    library to ensure that users of Synapse are protected from the
    recent OpenSSL security advisories, especially CVE-2021-3449.
    - Internal Changes
    - Enforce that `cryptography` dependency is up to date to
      ensure it has the most recent openssl patches. (#9697)
  - Note: we do not bump the cryptography dependency in our package
    as we use the system OpenSSL which gets the fix.
    Add dont-bump-cryptography-with-system-openssl.patch to comment
    out the dependency because otherwise the newer version
    requirement is enforced on startup
* Mon Mar 22 2021 Marcus Rueckert <>
  - Update to 1.30.0
    Note that this release deprecates the ability for appservices to
    call POST /_matrix/client/r0/register without the body parameter
    type. Appservice developers should use a type value of
    m.login.application_service as per the spec. In future releases,
    calling this endpoint with an access token - but without a
    m.login.application_service type - will fail.

      registering and logging in. (#9510, #9511, #9573)
    - Add synapse_federation_last_sent_pdu_time and
      synapse_federation_last_received_pdu_time prometheus metrics,
      which monitor federation delays by reporting the timestamps
      of messages sent and received to a set of remote servers.

      have been removed. They are replaced by
      synapse_federation_last_sent_pdu_time and
      synapse_federation_last_received_pdu_time. (#9540)
    - Registering an Application Service user without using the

  - Update to 1.28.0
    This release fixes the documentation included in v1.27.0 around
    the callback URI for SAML2 identity providers. If your server is
    configured to use single sign-on via a SAML2 IdP, you may need to
    make configuration changes. Please review UPGRADE.rst for more
    details on these changes.
    Removal warning
    - The v1 list accounts API is deprecated and will be removed in a
      future release. This API was undocumented and misleading. It
      can be replaced by the v2 list accounts API, which has been
      available since Synapse 1.7.0 (2019-12-13).
    - Please check if you're using any scripts which use the admin
      API and replace GET /_synapse/admin/v1/users/<user_id> with GET

* Tue Feb 16 2021 Marcus Rueckert <>
  - Update to 1.27.0
    Note that this release includes a change in Synapse to use Redis
    as a cache ─ as well as a pub/sub mechanism ─ if Redis support is
    enabled for workers. No action is needed by server
    administrators, and we do not expect resource usage of the Redis
    instance to change dramatically.
    This release also changes the callback URI for OpenID Connect
    (OIDC) identity providers. If your server is configured to use
    single sign-on via an OIDC/OAuth2 IdP, you may need to make
    configuration changes. Please review UPGRADE.rst for more details
    on these changes.
    This release also changes escaping of variables in the HTML
    templates for SSO or email notifications. If you have customised
    these templates, please review UPGRADE.rst for more details on
    these changes.

* Wed Jan 13 2021 Marcus Rueckert <>
  - Update to 1.25.0
    Ending Support for Python 3.5 and Postgres 9.5 With this release,
    the Synapse team is announcing a formal deprecation policy for
    our platform dependencies, like Python and PostgreSQL:
    All future releases of Synapse will follow the upstream
    end-of-life schedules.
    Which means:
    This is the last release which guarantees support for Python 3.5.
    We will end support for PostgreSQL 9.5 early next month.  We will
    end support for Python 3.6 and PostgreSQL 9.6 near the end of the
    year.  Crucially, this means we will not produce .deb packages
    for Debian 9 (Stretch) or Ubuntu 16.04 (Xenial) beyond the
    transition period described below.
    The website has convenient summaries of
    the support schedules for projects like Python and PostgreSQL.
    If you are unable to upgrade your environment to a supported
    version of Python or Postgres, we encourage you to consider using
    the Synapse Docker images instead.
    Transition Period We will make a good faith attempt to avoid
    breaking compatibility in all releases through the end of March
    2021. However, critical security vulnerabilities in dependencies
    or other unanticipated circumstances may arise which necessitate
    breaking compatibility earlier.
    We intend to continue producing .deb packages for Debian 9
    (Stretch) and Ubuntu 16.04 (Xenial) through the transition
    Removal warning The old Purge Room API and Shutdown Room API are
    deprecated and will be removed in a future release. They will be
    replaced by the Delete Room APIe
    POST /_synapse/admin/v1/rooms/<room_id>/delete replaces
    POST /_synapse/admin/v1/purge_room and
    POST /_synapse/admin/v1/shutdown_room/<room_id>.

  - Update to 1.24.0
    Due to the two security issues highlighted below, server
    administrators are encouraged to update Synapse. We are not aware
    of these vulnerabilities being exploited in the wild.
    - Security
    - There is a denial of service attack (CVE-2020-26257) against
      the federation APIs in which future events will not be
      correctly sent to other servers over federation. This affects
      all servers that participate in open federation. (Fixed in
    - Synapse may be affected by OpenSSL CVE-2020-1971.

  - Update to 1.23.0
    This release changes the way structured logging is configured.
    See the [upgrade notes](UPGRADE.rst#upgrading-to-v1230) for details.
    Note: We are aware of a trivially exploitable denial of service
    vulnerability in versions of Synapse prior to 1.20.0. Complete
    details will be disclosed on Monday, November 23rd. If you have

      /_synapse/admin/v1/event_reports) into detail and list
      endpoints. This is a breaking change to #8217 which was
      introduced in Synapse v1.21.0. Those who already use this API
      should check their scripts. Contributed by @dklimpel. (#8539)

      synapse_port_db script to fail. (#8386)
    - Fix a bug introduced in v1.20.0 which caused variables to be
      incorrectly escaped in Jinja2 templates. (#8394)
* Fri Sep 18 2020 Marcus Rueckert <>
  - Update to 1.20.0
    - Removal warning
    - Some older clients used a disallowed character (:) in the
      client_secret parameter of various endpoints. The incorrect
      behaviour was allowed for backwards compatibility, but is now
      being removed from Synapse as most users have updated their
      client. Further context can be found at #6766.
    - Historically, the Synapse Admin API has been accessible under
      the prefixes:
      In a future release, we will be dropping support for
      accessing Synapse's Admin API using the /_matrix/client/*
      prefixes. This makes it easier for homeserver admins to lock
      down external access to the Admin API endpoints.
    - Features
    - Add flags to the /versions endpoint for whether new rooms
      default to using E2EE. (#8343)
    - Add an endpoint to query your shared rooms with another user
      as an implementation of MSC2666. (#7785)
    - Iteratively encode JSON to avoid blocking the reactor.
      (#8013, #8116)
    - Add support for shadow-banning users (ignoring any message
      send requests). (#8034, #8092, #8095, #8142, #8152, #8157,
      [#8158], #8176)
    - Use the default template file when its equivalent is not
      found in a custom template directory. (#8037, #8107, #8252)
    - Add unread messages count to sync responses, as specified in
      MSC2654. (#8059, #8254, #8270, #8274)
    - Optimise /federation/v1/user/devices/ API by only returning
      devices with encryption keys. (#8198)

      get past events in a room when there is a malformed event.
    - Fix joining rooms over federation that include malformed
      events.  (#8324)

      related to notifications to misbehave following the
      implementation of unread counts. (#8280)

      messages will be queued for a remote server that has been
      unreachable. (#7864)
    - Fix Re-starting finished log context PUT-nnnn warning when
      event persistence failed. (#8081)
    - Synapse now correctly enforces the valid characters in the
      client_secret parameter used in various endpoints. (#8101)
    - Fix a bug introduced in v1.7.2 impacting message retention
      policies that would allow federated homeservers to dictate a
      retention period that's lower than the configured minimum
      allowed duration in the configuration file. (#8104)
    - Fix a long-standing bug where invalid JSON would be accepted
      by Synapse. (#8106)
    - Fix a bug introduced in Synapse v1.12.0 which could cause
      /sync requests to fail with a 404 if you had a very old
      outstanding room invite. (#8110)
    - Return a proper error code when the rooms of an invalid group
      are requested. (#8129)
    - Fix a bug which could cause a leaked postgres connection if
      synapse was set to daemonize. (#8131)

      provider documentation. (#8111)
    - Updated documentation to note that Synapse does not follow
      HTTP 308 redirects due to an upstream library not supporting
      them. Contributed by Ryan Cole. (#8120)
    - Explain better what GDPR-erased means when deactivating a
      user. (#8189)
    - Internal Changes
    - Blacklist MSC2753 SyTests until it is implemented. (#8285)

    * Bugfixes
    * Fix detection of out of sync remote device lists when receiving events
      from remote users.
    * Fix bug where Synapse fails to process an incoming event over federation
      if the server is missing too much of the event's auth chain.
    * Fix a bug causing Synapse to misinterpret the value off for
      encryption_enabled_by_default_for_room_type in its configuration file(s)

* Tue May 19 2020 Marcus Rueckert <>
  - Update to 1.13.0
    This release brings some potential changes necessary for certain
    configurations of Synapse:
    - If your Synapse is configured to use SSO and have a custom
      sso_redirect_confirm_template_dir configuration option set, you
      will need to duplicate the new sso_auth_confirm.html,
      sso_auth_success.html and sso_account_deactivated.html
      templates into that directory.
    - Synapse plugins using the complete_sso_login method of
      synapse.module_api.ModuleApi should instead switch to the
      async/await version, complete_sso_login_async, which includes
      additional checks. The former version is now deprecated.
    - A bug was introduced in Synapse 1.4.0 which could cause the
      room directory to be incomplete or empty if Synapse was
      upgraded directly from v1.2.1 or earlier, to versions between
      v1.4.0 and v1.12.x.
    Please review UPGRADE.rst for more details on these changes and
    for general upgrade guidance.
    For the complete list of changes please refer to

    but those were not up2date with the actual code.
* Mon Mar 23 2020 Marcus Rueckert <>
  - Update to 1.12.0
    Synapse may be vulnerable to request-smuggling attacks when it is
    used with a reverse-proxy. The vulnerabilties are fixed in
    Twisted 20.3.0, and are described in
    For a good introduction to this class of request-smuggling
    attacks, see
    We are not aware of these vulnerabilities being exploited in the
    wild, and do not believe that they are exploitable with current
    versions of any reverse proxies. Nevertheless, we recommend that
    all Synapse administrators ensure that they have the latest
    versions of the Twisted library to ensure that their installation
    remains secure.
    - Features
    - Changes related to room alias management
    - Publishing/removing a room from the room directory now
      requires the user to have a power level capable of
      modifying the canonical alias, instead of the room aliases.

      which has improved state resolution algorithms and event IDs).
    * The complete removal of "perspectives" support, with all homeservers now
      being required to use valid TLS certificates (there has been a transition

* Fri May 04 2018
  - Update to version v0.28.1:
      Clamp the allowed values of event depth received over federation to be
      [0, 2^63 - 1]. This mitigates an attack where malicious events
      injected with depth = 2^63 - 1 render rooms unusable. Depth is used to
      determine the cosmetic ordering of events within a room, and so the ordering
      of events in such a room will default to using stream_ordering rather than depth
      This is a temporary solution to mitigate abuse in the wild, whilst a long term solution
      is being implemented to improve how the depth parameter is used.
      Full details at
      Pin Twisted to <18.4 until we stop using the private _OpenSSLECCurve API.
