  Synapse 1.32.2 (2021-04-22)

  🚀 This release includes a fix for a regression introduced in 1.32.0.

  🛠 Bugfixes

  • 🛠 Fix a regression in Synapse 1.32.0 and 1.32.1 which caused LoggingContext errors in plugins. (#9857)

  Synapse 1.32.1 (2021-04-21)

  🚀 This release fixes a regression in Synapse 1.32.0 that caused connected Prometheus instances to become unstable.

  🚀 However, as this release is still subject to the LoggingContext change in 1.32.0, ⬇️ it is recommended to remain on or downgrade to 1.31.0.

  🛠 Bugfixes

  • 🛠 Fix a regression in Synapse 1.32.0 which caused Synapse to report large numbers of Prometheus time series, potentially overwhelming Prometheus instances. (#9854)

  Synapse 1.32.0 (2021-04-20)

  Note: This release introduces a regression that can overwhelm connected Prometheus instances. This issue was not present in ⬇️ 1.32.0rc1. If affected, it is recommended to downgrade to 1.31.0 in the meantime, and follow these instructions 🔊 to clean up any excess writeahead logs.

  Note: This release also mistakenly included a change that may affected Synapse 🌲 modules that import synapse.logging.context.LoggingContext, such as synapse-s3-storage-provider. 🛠 This will be fixed in a later Synapse version.

  Note: This release requires Python 3.6+ and Postgres 9.6+ or SQLite 3.22+.

  This release removes the deprecated GET /_synapse/admin/v1/users/<user_id> admin API. Please use the v2 API instead, which has improved capabilities.

  This release requires Application Services to use type m.login.application_service when registering users via the /_matrix/client/r0/register endpoint to comply with the spec. Please ensure your Application Services are up to date.

  📦 If you are using the packages.matrix.org Debian repository for Synapse packages, ⚡️ note that we have recently updated the expiry date on the gpg signing key. If you see an error similar to The following signatures were invalid: EXPKEYSIG F473DD4473365DE1, you will need to get a fresh copy of the keys. You can do so with:

  sudo wget -O /usr/share/keyrings/matrix-org-archive-keyring.gpg https://packages.matrix.org/debian/matrix-org-archive-keyring.gpg
  

  🛠 Bugfixes

  • 🛠 Fix the log lines of nested logging contexts. Broke in 1.32.0rc1. (#9829)

  Note: This release requires Python 3.6+ and Postgres 9.6+ or SQLite 3.22+.

  This release removes the deprecated GET /_synapse/admin/v1/users/<user_id> admin API. Please use the v2 API instead, which has improved capabilities.

  This release requires Application Services to use type m.login.application_services when registering users via the /_matrix/client/r0/register endpoint to comply with the spec. Please ensure your Application Services are up to date.

  Synapse 1.30.1 (2021-03-26)

  🚀 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.

  0️⃣ Note that Cryptography defaults to bundling its own statically linked copy of OpenSSL, which means that you may not be protected by your operating system's ⚡️ security updates.

  👍 It's also worth noting that Cryptography no longer supports Python 3.5, so 🚀 admins deploying to older environments may not be protected against this or 👍 future vulnerabilities. Synapse will be dropping support for Python 3.5 at the end of March.

  ⚡️ Updates to the Docker image

  • 🐳 Ensure that the docker container has up to date versions of openssl. (#9697)

  Internal Changes

  • Enforce that cryptography dependency is up to date to ensure it has the most recent openssl patches. (#9697)

  Synapse 1.30.0 (2021-03-22)

  🚀 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.

  No significant changes.

  Synapse 1.28.0 (2021-02-25)

  🚀 Note that this release drops support for ARMv7 in the official Docker images, due to repeated problems building for ARMv7 (and the associated maintenance burden this entails).

  📚 This release also 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 the [upgrade notes](docs/upgrade.md) for more details on these changes.

  Internal Changes

  • ⏪ Revert change in v1.28.0rc1 to remove the deprecated SAML endpoint. (#9474)

• v1.28.0.rc1 Changes

  February 19, 2021

  ⚠ 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 /_synapse/admin/v2/users.

  🔋 Features

  • 🆕 New admin API to get the context of an event: /_synapse/admin/rooms/{roomId}/context/{eventId}. (#9150)
  • Further improvements to the user experience of registration via single sign-on. (#9300, #9301)
  • ➕ Add hook to spam checker modules that allow checking file uploads and remote downloads. (#9311)
  • ➕ Add support for receiving OpenID Connect authentication responses via form POSTs rather than GETs. (#9376)
  • ➕ Add the shadow-banning status to the admin API for user info. (#9400)

  🛠 Bugfixes

  • 🛠 Fix bug introduced in Synapse 1.27.0rc1 which meant the "session expired" error page during SSO registration was badly formatted. (#9296)
  • Assert a maximum length for some parameters for spec compliance. (#9321, #9393)
  • 🛠 Fix additional errors when previewing URLs: "AttributeError 'NoneType' object has no attribute 'xpath'" and "ValueError: Unicode strings with encoding declaration are not supported. Please use bytes input or XML fragments without declaration.". (#9333)
  • 🛠 Fix a bug causing Synapse to impose the wrong type constraints on fields when processing responses from appservices to /_matrix/app/v1/thirdparty/user/{protocol}. (#9361)
  • 🛠 Fix bug where Synapse would occasionally stop reconnecting to Redis after the connection was lost. (#9391)
  • 🛠 Fix a long-standing bug when upgrading a room: "TypeError: '>' not supported between instances of 'NoneType' and 'int'". (#9395)
  • Reduce the amount of memory used when generating the URL preview of a file that is larger than the max_spider_size. (#9421)
  • 🛠 Fix a long-standing bug in the deduplication of old presence, resulting in no deduplication. (#9425)
  • The ui_auth.session_timeout config option can now be specified in terms of number of seconds/minutes/etc/. Contributed by Rishabh Arya. (#9426)
  • 🛠 Fix a bug introduced in v1.27.0: "TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType." related to the user directory. (#9428)

  Synapse 1.27.0 (2021-02-16)

  🚀 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) and SAML2 identity providers. If your server is configured to use single sign-on via an OIDC/OAuth2 or SAML2 IdP, you may need to make configuration changes. Please review the [upgrade notes](docs/upgrade.md) 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 the [upgrade notes](docs/upgrade.md) for more details on these changes.
