    Synapse 1.20.0rc1 (2020-09-08)
==============================

Removal warning
---------------

Some older clients used a [disallowed character](https://matrix.org/docs/spec/client_server/r0.6.1#post-matrix-client-r0-register-email-requesttoken) (`:`) 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](https://github.com/matrix-org/synapse/issues/6766).

Features
--------

- Add an endpoint to query your shared rooms with another user as an implementation of [MSC2666](https://github.com/matrix-org/matrix-doc/pull/2666). ([\#7785](https://github.com/matrix-org/synapse/issues/7785))
- Iteratively encode JSON to avoid blocking the reactor. ([\#8013](https://github.com/matrix-org/synapse/issues/8013), [\#8116](https://github.com/matrix-org/synapse/issues/8116))
- Add support for shadow-banning users (ignoring any message send requests). ([\#8034](https://github.com/matrix-org/synapse/issues/8034), [\#8092](https://github.com/matrix-org/synapse/issues/8092), [\#8095](https://github.com/matrix-org/synapse/issues/8095), [\#8142](https://github.com/matrix-org/synapse/issues/8142), [\#8152](https://github.com/matrix-org/synapse/issues/8152), [\#8157](https://github.com/matrix-org/synapse/issues/8157), [\#8158](https://github.com/matrix-org/synapse/issues/8158), [\#8176](https://github.com/matrix-org/synapse/issues/8176))

    Synapse 1.18.0 (2020-07-30)
===========================

Deprecation Warnings
--------------------

From 10th August 2020, we will no longer publish Docker images with the `-py3` tag suffix. The images tagged with the `-py3` suffix have been identical to the non-suffixed tags since release 0.99.0, and the suffix is obsolete.

On 10th August, we will remove the `latest-py3` tag. Existing per-release tags (such as `v1.18.0-py3`) will not be removed, but no new `-py3` tags will be added.

Scripts relying on the `-py3` suffix will need to be updated.

When setting up worker processes, we now recommend the use of a Redis server for replication. The old direct TCP connection method is deprecated and will be removed in a future release. See [docs/workers.md](https://github.com/matrix-org/synapse/blob/release-v1.18.0/docs/workers.md) for more details.

Improved Documentation

    Synapse 1.15.2 (2020-07-02)
===========================

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
-----------------

* A malicious homeserver could force Synapse to reset the state in a room to a
  small subset of the correct state. This affects all Synapse deployments which
  federate with untrusted servers. ([96e9afe6](https://github.com/matrix-org/synapse/commit/96e9afe62500310977dc3cbc99a8d16d3d2fa15c))
* HTML pages served via Synapse were vulnerable to clickjacking attacks. This
  predominantly affects homeservers with single-sign-on enabled, but all server
  administrators are encouraged to upgrade. ([ea26e9a9](https://github.com/matrix-org/synapse/commit/ea26e9a98b0541fc886a1cb826a38352b7599dbe))
