Synapse 1.92.3 (2023-09-18)

This is again a security update targeted at mitigating CVE-2023-4863. It turns out that libwebp is bundled statically in Pillow wheels so we need to update this dependency instead of libwebp package at the OS level.

Unlike what was advertised in 1.92.2 changelog this release also impacts PyPI wheels and Debian packages from matrix.org.

We encourage admins to upgrade as soon as possible.

Internal Changes

Pillow 10.0.1 is now mandatory because of libwebp CVE-2023-4863, since Pillow provides libwebp in the wheels. (#16347)

Updates to locked dependencies

Bump pillow from 10.0.0 to 10.0.1. (#16344)

Synapse 1.92.2 (2023-09-15)

This is a Docker-only update to mitigate CVE-2023-4863, a critical vulnerability in libwebp. Server admins not using Docker should ensure that their libwebp is up to date (if installed). We encourage admins to upgrade as soon as possible.

Updates to the Docker image

Update docker image to use Debian bookworm as the base. (#16324)

Synapse 1.92.1 (2023-09-12)

Security advisory

The following issues are fixed in 1.85.0 (and RCs).

GHSA-26c5-ppr8-f33p / CVE-2023-32682 — Low Severity

It may be possible for a deactivated user to login when using uncommon configurations.
GHSA-98px-6486-j7qc / CVE-2023-32683 — Low Severity

A discovered oEmbed or image URL can bypass the url_preview_url_blacklist setting potentially allowing server side request forgery or bypassing network policies. Impact is limited to IP addresses allowed by the url_preview_ip_range_blacklist setting (by default this only allows public IPs).

See the advisories for more details. If you have any questions, email security@matrix.org.

Synapse 1.84.1 (2023-05-26)

This patch release fixes a major issue with homeservers that do not have an instance_map defined but which do use workers. If you have already upgraded to Synapse 1.84.0 and your homeserver is working normally, then there is no need to update to this patch release.

Bugfixes

Fix a bug introduced in Synapse v1.84.0 where workers do not start up when no instance_map was provided. (#15672)

Internal Changes

Add dch and notify-send to the development Nix flake so that the release script can be used. (#15673)

Synapse 1.84.0 (2023-05-23)

The worker_replication_* configuration settings have been deprecated in favour of configuring the main process consistently with other instances in the instance_map. The deprecated settings will be removed in Synapse v1.88.0, but changing your configuration in advance is recommended. See the upgrade notes for more information.

Bugfixes

Fix a bug introduced in Synapse 1.84.0rc1 where errors during startup were not reported correctly on Python < 3.10. (#15599)

Synapse 1.81.0 (2023-04-11)

Synapse now attempts the versioned appservice paths before falling back to the legacy paths. Usage of the legacy routes should be considered deprecated.

Additionally, Synapse has supported sending the application service access token via the Authorization header since v1.70.0. For backwards compatibility it is also sent as the access_token query parameter. This is insecure and should be considered deprecated.

A future version of Synapse (v1.88.0 or later) will remove support for legacy application service routes and query parameter authorization.

No significant changes since 1.81.0rc2.

Synapse 1.76.0 (2023-01-31)

The 1.76 release is the first to enable faster joins (MSC3706 and MSC3902) by default. Admins can opt-out: see the upgrade notes for more details.

The upgrade from 1.75 to 1.76 changes the account data replication streams in a backwards-incompatible manner. Server operators running a multi-worker deployment should consult the upgrade notes.

Those who are poetry installing from source using our lockfile should ensure their poetry version is 1.3.2 or higher; see upgrade notes.

Notes on faster joins

The faster joins project sees the most benefit when joining a room with a large number of members (joined or historical). We expect it to be particularly useful for joining large public rooms like the Matrix HQ or Synapse Admins rooms.

After a faster join, Synapse considers that room "partially joined". In this state, you should be able to

read incoming messages;
see incoming state changes, e.g. room topic changes; and
send messages, if the room is unencrypted.

Synapse has to spend more effort to complete the join in the background. Once this finishes, you will be able to

send messages, if the room is in encrypted;
retrieve room history from before your join, if permitted by the room settings; and
access the full list of room members.

Improved Documentation

Describe the ideas and the internal machinery behind faster joins. (#14677)

Faster joins: allow non-lazy-loading ("eager") syncs to complete after a partial join by omitting partial state rooms until they become fully stated. (#14870)
