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](96e9afe625))
* 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](ea26e9a98b))
This was reported by [Quentin Gliech](https://sandhose.fr/).
Adds an option, `bind_new_user_emails_to_sydent`, which uses Sydent's [internal bind api](https://github.com/matrix-org/sydent#internal-bind-and-unbind-api) to automatically bind email addresses of users immediately after they register.
This is quite enterprise-specific, but could be generally useful to multiple organizations. This aims to solve the problem of requiring users to verify their email twice when using the functionality of an identity server in a corporate deployment - where both the homeserver and identity server are controlled. It does with while eliminating the need for the `account_threepid_delegates.email` option, which historically has been a very complicated option to reason about.
